+# Exposing Services with Traefik on Docker
+
+This guide will help you expose your services securely through Traefik Proxy using Docker. We'll cover routing HTTP and HTTPS traffic, implementing TLS, adding middlewares, Let's Encrypt integration, and sticky sessions.
+
+## Prerequisites
+
+- Docker and Docker Compose installed
+- Basic understanding of Docker concepts
+- Traefik deployed using the Traefik Docker Setup guide
+
+## Expose Your First HTTP Service
+
+Let's expose a simple HTTP service using the [whoami](https://hub.docker.com/r/traefik/whoami) application. This will demonstrate basic routing to a backend service.
+
+First, create a `docker-compose.yml` file:
+
+```yaml
+services:
+  traefik:
+    image: "traefik:v3.4"
+    container_name: "traefik"
+    restart: unless-stopped
+    security_opt:
+      - no-new-privileges:true
+    networks:
+      - proxy
+    command:
+      - "--providers.docker=true"
+      - "--providers.docker.exposedbydefault=false"
+      - "--providers.docker.network=proxy"
+      - "--entryPoints.web.address=:80"
+    ports:
+      - "80:80"
+      - "8080:8080"
+    volumes:
+      - "/var/run/docker.sock:/var/run/docker.sock:ro"
+
+  whoami:
+    image: "traefik/whoami"
+    restart: unless-stopped
+    networks:
+      - proxy
+    labels:
+      - "traefik.enable=true"
+      - "traefik.http.routers.whoami.rule=Host(`whoami.docker.localhost`)"
+      - "traefik.http.routers.whoami.entrypoints=web"
+
+networks:
+  proxy:
+    name: proxy
+```
+
+Save this as `docker-compose.yml` and start the services:
+
+```bash
+docker compose up -d
+```
+
+### Verify Your Service
+
+Your service is now available at http://whoami.docker.localhost/. Test that it works:
+
+```bash
+curl -H "Host: whoami.docker.localhost" http://localhost/
+```
+
+You should see output similar to:
+
+```bash
+Hostname: whoami
+IP: 127.0.0.1
+IP: ::1
+IP: 172.18.0.3
+IP: fe80::215:5dff:fe00:c9e
+RemoteAddr: 172.18.0.2:55108
+GET / HTTP/1.1
+Host: whoami.docker.localhost
+User-Agent: curl/7.68.0
+Accept: */*
+Accept-Encoding: gzip
+X-Forwarded-For: 172.18.0.1
+X-Forwarded-Host: whoami.docker.localhost
+X-Forwarded-Port: 80
+X-Forwarded-Proto: http
+X-Forwarded-Server: 5789f594e7d5
+X-Real-Ip: 172.18.0.1
+```
+
+This confirms that Traefik is successfully routing requests to your whoami application.
+
+## Add Routing Rules
+
+Now we'll enhance our routing by directing traffic to different services based on [URL paths](../reference/routing-configuration/http/router/rules-and-priority.md#path-pathprefix-and-pathregexp). This is useful for API versioning, frontend/backend separation, or organizing microservices.
+
+Update your `docker-compose.yml` to add another service:
+
+```yaml
+# ...
+
+# New service
+  whoami-api:
+    image: "traefik/whoami"
+    networks:
+      - proxy
+    container_name: "whoami-api"
+    environment:
+      - WHOAMI_NAME=API Service
+    labels:
+      - "traefik.enable=true"
+      # Path-based routing
+      - "traefik.http.routers.whoami-api.rule=Host(`whoami.docker.localhost`) && PathPrefix(`/api`)"
+      - "traefik.http.routers.whoami-api.entrypoints=web"
+```
+
+Apply the changes:
+
+```bash
+docker compose up -d
+```
+
+### Test the Path-Based Routing
+
+Verify that different paths route to different services:
+
+```bash
+# Root path should go to the main whoami service
+curl -H "Host: whoami.docker.localhost" http://localhost/
+
+# /api path should go to the whoami-api service
+curl -H "Host: whoami.docker.localhost" http://localhost/api
+```
+
+For the `/api` requests, you should see the response showing "API Service" in the environment variables section, confirming that your path-based routing is working correctly.
+
+## Enable TLS
+
+Let's secure our service with HTTPS by adding TLS. We'll start with a self-signed certificate for local development.
+
+### Create a Self-Signed Certificate
+
+Generate a self-signed certificate:
+
+```bash
+mkdir -p certs
+openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
+  -keyout certs/local.key -out certs/local.crt \
+  -subj "/CN=*.docker.localhost"
+```
+
+Create a directory for dynamic configuration and add a TLS configuration file:
+
+```bash
+mkdir -p dynamic
+cat > dynamic/tls.yml << EOF
+tls:
+  certificates:
+    - certFile: /certs/local.crt
+      keyFile: /certs/local.key
+EOF
+```
+
+Update your `docker-compose.yml` file with the following changes:
+
+```yaml
+services:
+  traefik:
+    image: "traefik:v3.4"
+    container_name: "traefik"
+    restart: unless-stopped
+    security_opt:

+      - "traefik.http.routers.whoami-api.entrypoints=websecure"
+      # Add the following label
+      - "traefik.http.routers.whoami-api.tls=true"
+
+networks:
+  proxy:
+    name: proxy
+```
+
+Apply the changes:
+
+```bash
+docker compose up -d
+```
+
+Your browser can access https://whoami.docker.localhost/ for the service. You'll need to accept the security warning for the self-signed certificate.
+
+## Add Middlewares
+
+Middlewares allow you to modify requests or responses as they pass through Traefik. Let's add two useful middlewares: [Headers](../reference/routing-configuration/http/middlewares/headers.md) for security and [IP allowlisting](../reference/routing-configuration/http/middlewares/ipallowlist.md) for access control.
+
+Add the following labels to your whoami service in `docker-compose.yml`:
+
+```yaml
+labels:
+  
+  # Secure Headers Middleware
+  - "traefik.http.middlewares.secure-headers.headers.frameDeny=true"
+  - "traefik.http.middlewares.secure-headers.headers.sslRedirect=true"
+  - "traefik.http.middlewares.secure-headers.headers.browserXssFilter=true"
+  - "traefik.http.middlewares.secure-headers.headers.contentTypeNosniff=true"
+  - "traefik.http.middlewares.secure-headers.headers.stsIncludeSubdomains=true"
+  - "traefik.http.middlewares.secure-headers.headers.stsPreload=true"
+  - "traefik.http.middlewares.secure-headers.headers.stsSeconds=31536000"
+  
+  # IP Allowlist Middleware
+  - "traefik.http.middlewares.ip-allowlist.ipallowlist.sourceRange=127.0.0.1/32,192.168.0.0/16,10.0.0.0/8"
+```
+
+Add the same middleware to your whoami-api service:
+
+```yaml
+labels:
+  - "traefik.http.routers.whoami-api.middlewares=secure-headers,ip-allowlist"
+```
+
+Apply the changes:
+
+```bash
+docker compose up -d
+```
+
+### Test the Middlewares
+
+Now let's verify that our middlewares are working correctly:
+
+Test the Secure Headers middleware:
+
+```bash
+curl -k -I -H "Host: whoami.docker.localhost" https://localhost/
+```
+
+In the response headers, you should see security headers set by the middleware:
+
+- `X-Frame-Options: DENY` 
+- `X-Content-Type-Options: nosniff`
+- `X-XSS-Protection: 1; mode=block`
+- `Strict-Transport-Security` with the appropriate settings
+
+Test the IP Allowlist middleware:
+
+If your request comes from an IP that's in the allow list (e.g., 127.0.0.1), it should succeed:
+
+```bash
+curl -k -I -H "Host: whoami.docker.localhost" https://localhost/
+```
+
+If you try to access from an IP not in the allow list, the request will be rejected with a `403` Forbidden response. To simulate this in a local environment, you can modify the middleware configuration temporarily to exclude your IP address, then test again.
+
+## Generate Certificates with Let's Encrypt
+
+Let's Encrypt provides free, automated TLS certificates. Let's configure Traefik to automatically obtain and renew certificates for our services.
+
+Instead of using self-signed certificates, update your existing `docker-compose.yml` file with the following changes:
+
+Add the Let's Encrypt certificate resolver to the Traefik service command section:
+
+```yaml
+command:
+  - "--api.insecure=false"
+  - "--api.dashboard=true"
+  - "--providers.docker=true"
+  - "--providers.docker.exposedbydefault=false"
+  - "--providers.docker.network=proxy"
+  - "--entryPoints.web.address=:80"
+  - "--entryPoints.websecure.address=:443"
+  - "--entryPoints.websecure.http.tls=true"
+  - "--entryPoints.web.http.redirections.entryPoint.to=websecure"
+  - "--entryPoints.web.http.redirections.entryPoint.scheme=https"
+  # Let's Encrypt configuration
+  - "--certificatesresolvers.le.acme.email=your-email@example.com" # replace with your actual email
+  - "--certificatesresolvers.le.acme.storage=/letsencrypt/acme.json"
+  - "--certificatesresolvers.le.acme.httpchallenge.entrypoint=web"
+```
+
+Add a volume for Let's Encrypt certificates:
+
+```yaml
+volumes:
+  # ...Existing volumes...
+  - "./letsencrypt:/letsencrypt"
+```
+
+Update your service labels to use the certificate resolver:
+
+```yaml
+labels:
+  - "traefik.http.routers.whoami.tls.certresolver=le"
+```
+
+Do the same for any other services you want to secure:
+
+```yaml
+labels:
+  - "traefik.http.routers.whoami-api.tls.certresolver=le"
+```
+
+Create a directory for storing Let's Encrypt certificates:
+
+```bash
+mkdir -p letsencrypt
+```
+
+Apply the changes:
+
+```bash
+docker compose up -d
+```
+
+!!! important "Public DNS Required"
+    Let's Encrypt may require a publicly accessible domain to validate domain ownership. For testing with local domains like `whoami.docker.localhost`, the certificate will remain self-signed. In production, replace it with a real domain that has a publicly accessible DNS record pointing to your Traefik instance.
+
+Once the certificate is issued, you can verify it:
+
+```bash
+# Verify the certificate chain
+curl -v https://whoami.docker.localhost/ 2>&1 | grep -i "server certificate"
+```
+
+You should see that your certificate is issued by Let's Encrypt.
+
+## Configure Sticky Sessions
+
+Sticky sessions ensure that a user's requests always go to the same backend server, which is essential for applications that maintain session state. Let's implement sticky sessions for our whoami service.
+
+### First, Add Sticky Session Labels
+
+Add the following labels to your whoami service in the `docker-compose.yml` file:
+
+```yaml
+labels:
+  - "traefik.http.services.whoami.loadbalancer.sticky.cookie=true"
+  - "traefik.http.services.whoami.loadbalancer.sticky.cookie.name=sticky_cookie"
+  - "traefik.http.services.whoami.loadbalancer.sticky.cookie.secure=true"
+  - "traefik.http.services.whoami.loadbalancer.sticky.cookie.httpOnly=true"
+```
+
+Apply the changes:
+
+```bash
+docker compose up -d
+```
+
+### Then, Scale Up the Service
+
+To demonstrate sticky sessions with Docker, use Docker Compose's scale feature:
+
+```bash
+docker compose up -d --scale whoami=3
+```
+
+This creates multiple instances of the whoami service.
+
+!!! important "Scaling After Configuration Changes"
+    If you run `docker compose up -d` after scaling, it will reset the number of whoami instances back to 1. Always scale after applying configuration changes and starting the services.
+
+### Test Sticky Sessions
+
+You can test the sticky sessions by making multiple requests and observing that they all go to the same backend container:
+
+```bash
+# First request - save cookies to a file
+curl -k -c cookies.txt -H "Host: whoami.docker.localhost" https://localhost/
+
+# Subsequent requests - use the cookies
+curl -k -b cookies.txt -H "Host: whoami.docker.localhost" https://localhost/
+curl -k -b cookies.txt -H "Host: whoami.docker.localhost" https://localhost/
+```
+
+Pay attention to the `Hostname` field in each response - it should remain the same across all requests when using the cookie file, confirming that sticky sessions are working.
+
+For comparison, try making requests without the cookie:
+
+```bash
+# Requests without cookies should be load-balanced across different containers
+curl -k -H "Host: whoami.docker.localhost" https://localhost/
+curl -k -H "Host: whoami.docker.localhost" https://localhost/
+```
+
+You should see different `Hostname` values in these responses, as each request is load-balanced to a different container.
+
+!!! important "Browser Testing"
+    When testing in browsers, you need to use the same browser session to maintain the cookie. The cookie is set with `httpOnly` and `secure` flags for security, so it will only be sent over HTTPS connections and won't be accessible via JavaScript.
+
+For more advanced configuration options, see the [reference documentation](../reference/routing-configuration/http/load-balancing/service.md).

+# Exposing Services with Traefik on Docker Swarm
+
+This guide will help you expose your services securely through Traefik Proxy using Docker Swarm. We'll cover routing HTTP and HTTPS traffic, implementing TLS, adding middlewares, Let's Encrypt integration, and sticky sessions.
+
+## Prerequisites
+
+- Docker Swarm cluster initialized
+- Basic understanding of Docker Swarm concepts
+- Traefik deployed using the Traefik Docker Swarm Setup guide
+
+## Expose Your First HTTP Service
+
+Let's expose a simple HTTP service using the [whoami](https://hub.docker.com/r/traefik/whoami) application. This will demonstrate basic routing to a backend service.
+
+First, update your existing `docker-compose.yml` file if you haven't already:
+
+```yaml
+services:
+  whoami:
+    image: traefik/whoami
+    networks:
+      - traefik_proxy
+    deploy:
+      replicas: 3
+      labels:
+        - "traefik.enable=true"
+        - "traefik.http.routers.whoami.rule=Host(`whoami.swarm.localhost`)"
+        - "traefik.http.routers.whoami.entrypoints=web,websecure"
+```
+
+Save this as `docker-compose.yml` and deploy the stack:
+
+```bash
+docker stack deploy -c docker-compose.yml traefik
+```
+
+### Verify Your Service
+
+Your service is now available at http://whoami.swarm.localhost/. Test that it works:
+
+```bash
+curl -H "Host: whoami.swarm.localhost" http://localhost/
+```
+
+You should see output similar to:
+
+```bash
+Hostname: whoami.1.7c8f7tr56q3p949rscxrkp80e
+IP: 127.0.0.1
+IP: ::1
+IP: 10.0.1.8
+IP: fe80::215:5dff:fe00:c9e
+RemoteAddr: 10.0.1.2:45098
+GET / HTTP/1.1
+Host: whoami.swarm.localhost
+User-Agent: curl/7.68.0
+Accept: */*
+Accept-Encoding: gzip
+X-Forwarded-For: 10.0.1.1
+X-Forwarded-Host: whoami.swarm.localhost
+X-Forwarded-Port: 80
+X-Forwarded-Proto: http
+X-Forwarded-Server: 5789f594e7d5
+X-Real-Ip: 10.0.1.1
+```
+
+This confirms that Traefik is successfully routing requests to your whoami application.
+
+## Add Routing Rules
+
+Now we'll enhance our routing by directing traffic to different services based on [URL paths](../reference/routing-configuration/http/router/rules-and-priority.md#path-pathprefix-and-pathregexp). This is useful for API versioning, frontend/backend separation, or organizing microservices.
+
+Update your `docker-compose.yml` to add another service:
+
+```yaml
+# ...
+
+# New service
+  whoami-api:
+    image: traefik/whoami
+    networks:
+      - traefik_proxy
+    environment:
+      - WHOAMI_NAME=API Service
+    deploy:
+      replicas: 2
+      labels:
+        - "traefik.enable=true"
+        # Path-based routing
+        - "traefik.http.routers.whoami-api.rule=Host(`whoami.swarm.localhost`) && PathPrefix(`/api`)"
+        - "traefik.http.routers.whoami-api.entrypoints=web,websecure"
+        - "traefik.http.routers.whoami-api.service=whoami-api-svc"
+        - "traefik.http.services.whoami-api-svc.loadbalancer.server.port=80"
+
+# ...
+```
+
+Apply the changes:
+
+```bash
+docker stack deploy -c docker-compose.yml traefik
+```
+
+### Test the Path-Based Routing
+
+Verify that different paths route to different services:
+
+```bash
+# Root path should go to the main whoami service
+curl -H "Host: whoami.swarm.localhost" http://localhost/
+
+# /api path should go to the whoami-api service
+curl -H "Host: whoami.swarm.localhost" http://localhost/api
+```
+
+For the `/api` requests, you should see the response showing "API Service" in the environment variables section, confirming that your path-based routing is working correctly.
+
+## Enable TLS
+
+Let's secure our service with HTTPS by adding TLS. We'll start with a self-signed certificate for local development.
+
+### Create a Self-Signed Certificate 
+
+Generate a self-signed certificate and dynamic config file to tell Traefik where the cert lives:
+
+```bash
+mkdir -p certs
+
+# key + cert (valid for one year)
+openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
+  -keyout certs/local.key -out certs/local.crt \
+  -subj "/CN=*.swarm.localhost"
+
+# dynamic config that tells Traefik where the cert lives
+cat > certs/tls.yml <<'EOF'
+tls:
+  certificates:
+    - certFile: /certificates/local.crt
+      keyFile:  /certificates/local.key
+EOF
+```
+
+Create a Docker config for the certificate files:
+
+```bash
+docker config create swarm-cert.crt certs/local.crt
+docker config create swarm-cert.key certs/local.key
+docker config create swarm-tls.yml certs/tls.yml
+```
+
+Update your `docker-compose.yml` file with the following changes:
+
+```yaml
+# Add to the Traefik command section:
+command:
+  # ... existing commands ...
+  - "--entryPoints.websecure.address=:443"
+  - "--entryPoints.websecure.http.tls=true"
+  - "--providers.file.directory=/etc/traefik/dynamic"
+```
+
+```yaml
+# Add to the root of your docker-compose.yml file:
+configs:
+  swarm-cert.crt:
+    file: ./certs/local.crt
+  swarm-cert.key:
+    file: ./certs/local.key
+  swarm-tls.yml:
+    file: ./certs/tls.yml
+```
+
+Deploy the stack:
+
+```bash
+docker stack deploy -c docker-compose.yml traefik
+```
+
+Your browser can access https://whoami.swarm.localhost/ for the service. You'll need to accept the security warning for the self-signed certificate.
+
+## Add Middlewares
+
+Middlewares allow you to modify requests or responses as they pass through Traefik. Let's add two useful middlewares: [Headers](../reference/routing-configuration/http/middlewares/headers.md) for security and [IP allowlisting](../reference/routing-configuration/http/middlewares/ipallowlist.md) for access control.
+
+Add the following labels to your whoami service deployment section in `docker-compose.yml`:
+
+```yaml
+deploy:
+  # ... existing configuration ...
+  labels:
+    # ... existing labels ...
+    
+    # Secure Headers Middleware
+    - "traefik.http.middlewares.secure-headers.headers.frameDeny=true"
+    - "traefik.http.middlewares.secure-headers.headers.sslRedirect=true"
+    - "traefik.http.middlewares.secure-headers.headers.browserXssFilter=true"
+    - "traefik.http.middlewares.secure-headers.headers.contentTypeNosniff=true"
+    - "traefik.http.middlewares.secure-headers.headers.stsIncludeSubdomains=true"
+    - "traefik.http.middlewares.secure-headers.headers.stsPreload=true"
+    - "traefik.http.middlewares.secure-headers.headers.stsSeconds=31536000"
+    
+    # IP Allowlist Middleware
+    - "traefik.http.middlewares.ip-allowlist.ipallowlist.sourceRange=127.0.0.1/32,192.168.0.0/16,10.0.0.0/8"
+    
+    # Apply the middlewares
+    - "traefik.http.routers.whoami.middlewares=secure-headers,ip-allowlist"
+```
+
+Add the same middleware to your whoami-api service:
+
+```yaml
+deploy:
+  # ... existing configuration ...
+  labels:
+    # ... existing labels ...
+    - "traefik.http.routers.whoami-api.middlewares=secure-headers,ip-allowlist"
+```
+
+Apply the changes:
+
+```bash
+docker stack deploy -c docker-compose.yml traefik
+```
+
+### Test the Middlewares
+
+Now let's verify that our middlewares are working correctly:
+
+Test the Secure Headers middleware:
+
+```bash
+curl -k -I -H "Host: whoami.swarm.localhost" https://localhost/
+```
+
+In the response headers, you should see security headers set by the middleware:
+
+- `X-Frame-Options: DENY`
+- `X-Content-Type-Options: nosniff`
+- `X-XSS-Protection: 1; mode=block`
+- `Strict-Transport-Security` with the appropriate settings
+
+Test the IP Allowlist middleware:
+
+If your request comes from an IP that's in the allow list (e.g., 127.0.0.1), it should succeed:
+
+```bash
+curl -k -I -H "Host: whoami.swarm.localhost" https://localhost/
+```
+
+If you try to access from an IP not in the allow list, the request will be rejected with a `403` Forbidden response. To simulate this in a local environment, you can modify the middleware configuration temporarily to exclude your IP address, then test again.
+
+## Generate Certificates with Let's Encrypt
+
+Let's Encrypt provides free, automated TLS certificates. Let's configure Traefik to automatically obtain and renew certificates for our services.
+
+Instead of using self-signed certificates, update your existing `docker-compose.yml` file with the following changes:
+
+Add the Let's Encrypt certificate resolver to the Traefik service command section:
+
+```yaml
+command:
+  # ... existing commands ...
+  # Let's Encrypt configuration
+  - "--certificatesresolvers.le.acme.email=your-email@example.com" # replace with your actual email
+  - "--certificatesresolvers.le.acme.storage=/letsencrypt/acme.json"
+  - "--certificatesresolvers.le.acme.httpchallenge.entrypoint=web"
+```
+
+Add a volume for Let's Encrypt certificates:
+
+```yaml
+volumes:
+  # ...Existing volumes...
+  - letsencrypt:/letsencrypt
+```
+
+Update your service labels to use the certificate resolver:
+
+```yaml
+labels:
+  # ... existing labels ...
+  - "traefik.http.routers.whoami.tls.certresolver=le"
+```
+
+Do the same for any other services you want to secure:
+
+```yaml
+labels:
+  # ... existing labels ...
+  - "traefik.http.routers.whoami-api.tls.certresolver=le"
+```
+
+Create a named volume for storing Let's Encrypt certificates by adding to the volumes section:
+
+```yaml
+volumes:
+  # ... existing volumes ...
+  letsencrypt:
+    driver: local
+```
+
+Apply the changes:
+
+```bash
+docker stack deploy -c docker-compose.yml traefik
+```
+
+!!! important "Public DNS Required"
+    Let's Encrypt may require a publicly accessible domain to validate domain ownership. For testing with local domains like `whoami.swarm.localhost`, the certificate will remain self-signed. In production, replace it with a real domain that has a publicly accessible DNS record pointing to your Traefik instance.
+
+Once the certificate is issued, you can verify it:
+
+```bash
+# Verify the certificate chain
+curl -v https://whoami.swarm.localhost/ 2>&1 | grep -i "server certificate"
+```
+
+You should see that your certificate is issued by Let's Encrypt.
+
+## Configure Sticky Sessions
+
+Sticky sessions ensure that a user's requests always go to the same backend server, which is essential for applications that maintain session state. Let's implement sticky sessions for our whoami service.
+
+Docker Swarm already has multiple replicas running; we'll now add sticky session configuration. Update your whoami service in the `docker-compose.yml` file:
+
+### Add Sticky Session Configuration
+
+Add the following labels to your whoami service in the `docker-compose.yml` file:
+
+```yaml
+deploy:
+  # ... existing configuration ...
+  labels:
+    # ... existing labels ...
+    
+    # Sticky Sessions Configuration
+    - "traefik.http.services.whoami.loadbalancer.sticky.cookie=true"
+    - "traefik.http.services.whoami.loadbalancer.sticky.cookie.name=sticky_cookie"
+    - "traefik.http.services.whoami.loadbalancer.sticky.cookie.secure=true"
+    - "traefik.http.services.whoami.loadbalancer.sticky.cookie.httpOnly=true"
+```
+
+Apply the changes:
+
+```bash
+docker stack deploy -c docker-compose.yml traefik
+```
+
+### Test Sticky Sessions
+
+You can test the sticky sessions by making multiple requests and observing that they all go to the same backend container:
+
+```bash
+# First request - save cookies to a file
+curl -k -c cookies.txt -H "Host: whoami.swarm.localhost" https://localhost/
+
+# Subsequent requests - use the cookies
+curl -k -b cookies.txt -H "Host: whoami.swarm.localhost" https://localhost/
+curl -k -b cookies.txt -H "Host: whoami.swarm.localhost" https://localhost/
+```
+
+Pay attention to the `Hostname` field in each response - it should remain the same across all requests when using the cookie file, confirming that sticky sessions are working.
+
+For comparison, try making requests without the cookie:
+
+```bash
+# Requests without cookies should be load-balanced across different containers
+curl -k -H "Host: whoami.swarm.localhost" https://localhost/
+curl -k -H "Host: whoami.swarm.localhost" https://localhost/
+```
+
+You should see different `Hostname` values in these responses, as each request is load-balanced to a different container.
+
+!!! important "Browser Testing"
+    When testing in browsers, you need to use the same browser session to maintain the cookie. The cookie is set with `httpOnly` and `secure` flags for security, so it will only be sent over HTTPS connections and won't be accessible via JavaScript.
+
+For more advanced configuration options, see the [reference documentation](../reference/routing-configuration/http/load-balancing/service.md).
+
+## Conclusion
+
+In this guide, you've learned how to:
+
+- Expose HTTP services through Traefik in Docker Swarm
+- Set up path-based routing to direct traffic to different backend services
+- Secure your services with TLS using self-signed certificates
+- Add security with middlewares like secure headers and IP allow listing
+- Automate certificate management with Let's Encrypt
+- Implement sticky sessions for stateful applications
+
+These fundamental capabilities provide a solid foundation for exposing any application through Traefik Proxy in Docker Swarm. Each of these can be further customized to meet your specific requirements.
+
+### Next Steps
+
+Now that you understand the basics of exposing services with Traefik Proxy, you might want to explore:

+title: Extend Traefik
+description: Extend Traefik with custom plugins using Yaegi and WebAssembly.
+---
+
+# Extend Traefik
+
+Plugins are a powerful feature for extending Traefik with custom features and behaviors. The [Plugin Catalog](https://plugins.traefik.io/) is a software-as-a-service (SaaS) platform that provides an exhaustive list of the existing plugins.
+
+??? note "Plugin Catalog Access"
+    You can reach the [Plugin Catalog](https://plugins.traefik.io/) from the Traefik Dashboard using the `Plugins` menu entry.
+
+## Add a new plugin to a Traefik instance
+
+To add a new plugin to a Traefik instance, you must change that instance's install (static) configuration. Each plugin's **Install** section provides an install (static) configuration example. Many plugins have their own section in the Traefik routing (dynamic) configuration.
+
+!!! danger "Experimental Features"
+    Plugins can change the behavior of Traefik in unforeseen ways. Exercise caution when adding new plugins to production Traefik instances.
+
+To learn more about how to add a new plugin to a Traefik instance, please refer to the [developer documentation](https://plugins.traefik.io/install).
+
+## Plugin Systems
+
+Traefik supports two different plugin systems, each designed for different use cases and developer preferences.
+
+### Yaegi Plugin System
+
+Traefik [Yaegi](https://github.com/traefik/yaegi) plugins are developed using the Go language. It is essentially a Go package. Unlike pre-compiled plugins, Yaegi plugins are executed on the fly by Yaegi, a Go interpreter embedded in Traefik.
+
+This approach eliminates the need for compilation and a complex toolchain, making plugin development as straightforward as creating web browser extensions. Yaegi plugins support both middleware and provider functionality.
+
+#### Key characteristics
+
+- Written in Go language
+- No compilation required
+- Executed by embedded interpreter
+- Supports full Go feature set
+- Hot-reloadable during development
+
+### WebAssembly (WASM) Plugin System
+
+Traefik WASM plugins can be developed using any language that compiles to WebAssembly (WASM). This method is based on [http-wasm](https://http-wasm.io/).
+
+WASM plugins compile to portable binary modules that execute with near-native performance while maintaining security isolation.
+
+#### Key characteristics
+
+- Multi-language support (Go, Rust, C++, etc.)
+- Compiled to WebAssembly binary
+- Near-native performance
+- Strong security isolation
+- Currently supports middleware only
+
+## Build Your Own Plugins
+
+Traefik users can create their own plugins and share them with the community using the [Plugin Catalog](https://plugins.traefik.io/). To learn more about Traefik plugin creation, please refer to the [developer documentation](https://plugins.traefik.io/create).

+
+# Getting Started with Docker and Traefik
+
+Docker is a first-class citizen in Traefik, offering native support for Docker containers and services. 
+Whether you're using Docker Compose or running containers directly, Traefik provides a seamless experience for managing your Docker traffic.
+
+This guide shows you how to:
+
+- Install Traefik using Docker
+- Expose the Traefik dashboard
+- Deploy a sample application
+- Configure basic routing
+
+## Prerequisites
+
+- Docker 
+- Docker Compose (optional)
+
+## Install Traefik
+
+### Using Docker Compose
+
+Create a Docker Compose file. 
+This configuration:
+
+- Exposes ports 80 and 8080. 
+- Enables the Docker provider
+- Configures the dashboard with basic settings. Port 8080 serves the dashboard because we enabled `--api.insecure=true` (development use only)
+- Mounts the Docker socket for container discovery
+
+```yaml
+# docker-compose.yml
+services:
+  traefik:
+    image: traefik:v3.5
+    command:
+      - "--api.insecure=true"
+      - "--providers.docker=true"
+      - "--entrypoints.web.address=:80"
+    ports:
+      - "80:80"
+      - "8080:8080"
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock
+```
+
+Start Traefik:
+
+```bash
+docker-compose up -d
+```
+
+### Using Docker CLI
+
+Alternatively, you can run Traefik directly with Docker. 
+This command:
+
+- Exposes ports 80 and 8080 for web traffic and dashboard access
+- Mounts the configuration file and Docker socket
+- Uses the same configuration as the Docker Compose example
+
+Create a configuration file:
+
+```yaml
+# traefik.yml
+api:
+  insecure: true
+entryPoints:
+  web:
+    address: ":80"
+providers:
+  docker: {}
+```
+
+Start Traefik:
+
+```bash
+docker run -d \
+  -p 80:80 \
+  -p 8080:8080 \
+  -v $PWD/traefik.yml:/etc/traefik/traefik.yml \
+  -v /var/run/docker.sock:/var/run/docker.sock \
+  traefik:v3.5
+```
+
+## Expose the Dashboard
+
+Because we explicitly enabled insecure mode, the [dashboard](../reference/install-configuration/api-dashboard.md) is reachable on port 8080 without authentication. 
+**Do not enable this flag in production**.
+
+You can access the dashboard at:
+
+[http://localhost:8080/dashboard/](http://localhost:8080/dashboard/)
+
+![Traefik Dashboard Screenshot](../assets/img/getting-started/traefik-dashboard.png)
+
+## Deploy a Sample Application
+
+Create a whoami service:
+
+```yaml
+# whoami.yml
+services:
+  whoami:
+    image: traefik/whoami
+    labels:
+      - "traefik.http.routers.whoami.rule=Host(`whoami.localhost`)"
+```
+
+Apply the configuration:
+
+```bash
+docker-compose -f whoami.yml up -d
+```
+
+## Test Your Setup
+
+You can use the following curl command to verify that the application is correctly exposed:
+
+```bash
+curl http://whoami.localhost
+
+Hostname: 068c0a29a8b7
+IP: 127.0.0.1
+IP: ::1
+IP: 192.168.147.3
+RemoteAddr: 192.168.147.2:56006
+GET / HTTP/1.1
+Host: whoami.localhost
+User-Agent: curl/8.7.1
+Accept: */*
+Accept-Encoding: gzip
+X-Forwarded-For: 192.168.147.1
+X-Forwarded-Host: whoami.localhost
+X-Forwarded-Port: 80
+X-Forwarded-Proto: http
+X-Forwarded-Server: 9232cdd4fd6c
+X-Real-Ip: 192.168.147.1
+```
+
+You can also open [http://whoami.localhost](http://whoami.localhost) in a browser to test the application:
+
+![whoami application Screenshot](../assets/img/getting-started/whoami-localhost.png)
+
+If you navigate to the **HTTP Routers** section of the Traefik dashboard, you can see that the `whoami.localhost` route is managed by the Traefik Docker provider:
+
+![Traefik Dashboard HTTP Routers Section Screenshot](../assets/img/getting-started/docker-router.png)
+
+That's it! You've successfully deployed Traefik and configured routing in Docker.

+
+# Getting Started with Kubernetes and Traefik
+
+Kubernetes is a first-class citizen in Traefik, offering native support for Kubernetes resources and the latest Kubernetes standards. 
+Whether you're using Traefik's [IngressRoute CRD](../reference/routing-configuration/kubernetes/crd/http/ingressroute.md), [Ingress](../reference/routing-configuration/kubernetes/ingress.md) or the [Kubernetes Gateway API](../reference/routing-configuration/kubernetes/gateway-api.md), 
+Traefik provides a seamless experience for managing your Kubernetes traffic.
+
+This guide shows you how to:
+
+- Create a Kubernetes cluster using k3d
+- Install Traefik using Helm
+- Expose the Traefik dashboard
+- Deploy a sample application
+- Configure basic routing with IngressRoute and Gateway API
+
+## Prerequisites
+
+- Kubernetes
+- Helm 3
+- kubectl
+- k3d (for local cluster creation)
+
+## Create a Kubernetes Cluster
+
+### Using k3d
+
+Create a cluster with the following command. This command:
+
+- Creates a k3d cluster named "traefik"
+- Maps ports 80, 443, and 8000 to the loadbalancer for accessing services
+- Disables the built-in Traefik ingress controller to avoid conflicts
+
+```bash
+k3d cluster create traefik \
+  --port 80:80@loadbalancer \
+  --port 443:443@loadbalancer \
+  --port 8000:8000@loadbalancer \
+  --k3s-arg "--disable=traefik@server:0"
+```
+
+Configure kubectl:
+
+```bash
+kubectl cluster-info --context k3d-traefik
+```
+
+## Install Traefik
+
+### Using Helm Values File
+
+Add the Traefik Helm repository:
+
+```bash
+helm repo add traefik https://traefik.github.io/charts
+helm repo update
+```
+
+Create a values file. This configuration:
+
+- Maps ports 80 and 443 to the web and websecure [entrypoints](../reference/install-configuration/entrypoints.md)
+- Enables the [dashboard](../reference/install-configuration/api-dashboard.md) with a specific hostname rule
+- Enables the [Kubernetes Gateway API provider](../reference/routing-configuration/kubernetes/gateway-api.md)
+- Allows the Gateway to expose [HTTPRoutes](https://gateway-api.sigs.k8s.io/api-types/httproute/) from all namespaces
+
+```yaml
+# values.yaml
+ingressRoute:
+  dashboard:
+    enabled: true
+    matchRule: Host(`dashboard.localhost`)
+    entryPoints:
+      - web
+providers:
+  kubernetesGateway:
+    enabled: true
+gateway:
+  namespacePolicy: All
+```
+
+!!! info
+    The [KubernetesCRD](../reference/install-configuration/providers/kubernetes/kubernetes-crd.md) provider is enabled by default when using the Helm chart so we don't need to set it in the values file.
+
+Install Traefik:
+
+```bash
+helm install traefik traefik/traefik -f values.yaml --wait
+```
+
+### Using Helm CLI Arguments
+
+Alternatively, you can install Traefik using CLI arguments. This command:
+
+- Maps ports `30000` and `30001` to the web and websecure entrypoints
+- Enables the dashboard with a specific hostname rule
+- Enables the [Kubernetes Gateway API provider](../reference/routing-configuration/kubernetes/gateway-api.md)
+- Allows the Gateway to expose HTTPRoutes from all namespaces
+
+```bash
+helm install traefik traefik/traefik --wait \
+  --set ingressRoute.dashboard.enabled=true \
+  --set ingressRoute.dashboard.matchRule='Host(`dashboard.localhost`)' \
+  --set ingressRoute.dashboard.entryPoints={web} \
+  --set providers.kubernetesGateway.enabled=true \
+  --set gateway.namespacePolicy=All
+```
+
+!!! info
+    The [KubernetesCRD](../reference/install-configuration/providers/kubernetes/kubernetes-crd.md) provider is enabled by default when using the Helm chart so we don't need to set it in the CLI arguments.
+
+When Traefik is installed with the Gateway API provider enabled, it automatically creates a default GatewayClass named **traefik**:
+
+```bash
+kubectl describe GatewayClass traefik
+```
+
+## Expose the Dashboard
+
+The dashboard is exposed with an [IngressRoute](../reference/routing-configuration/kubernetes/crd/http/ingressroute.md) provided by the Chart, as we defined in the helm values during installation. 
+
+Access it at:
+
+[http://dashboard.localhost/dashboard/](http://dashboard.localhost/dashboard/)
+
+![Traefik Dashboard Screenshot](../assets/img/getting-started/traefik-dashboard.png)
+
+## Deploy a Sample Application
+
+Create a deployment:
+
+```yaml
+# whoami.yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: whoami
+spec:
+  replicas: 2
+  selector:
+    matchLabels:
+      app: whoami
+  template:
+    metadata:
+      labels:
+        app: whoami
+    spec:

+        - name: whoami
+          image: traefik/whoami
+          ports:
+            - containerPort: 80
+```
+
+Create a service:
+
+```yaml
+# whoami-service.yaml
+apiVersion: v1
+kind: Service
+metadata:
+  name: whoami
+spec:
+  ports:
+    - port: 80
+  selector:
+    app: whoami
+```
+
+Apply the manifests:
+
+```bash
+kubectl apply -f whoami.yaml
+kubectl apply -f whoami-service.yaml
+```
+
+## Exposing the Application Using an IngressRoute (CRD)
+
+Create an IngressRoute:
+
+```yaml
+# whoami-ingressroute.yaml
+apiVersion: traefik.io/v1alpha1
+kind: IngressRoute
+metadata:
+  name: whoami
+spec:
+  entryPoints:
+    - web
+  routes:
+    - match: Host(`whoami.localhost`)
+      kind: Rule
+      services:
+        - name: whoami
+          port: 80
+```
+
+Apply the manifest:
+
+```bash
+kubectl apply -f whoami-ingressroute.yaml
+```
+
+### Test Your Setup
+
+You can use the following curl command to verify that the application is correctly exposed:
+
+```bash
+curl http://whoami.localhost
+
+Hostname: whoami-76c9859cfc-6v8hh
+IP: 127.0.0.1

+X-Forwarded-Server: traefik-598946cd7-zds59
+X-Real-Ip: 127.0.0.1
+```
+
+You can also visit [http://whoami.localhost](http://whoami.localhost) in a browser to verify that the application is exposed correctly:
+
+![whoami application Screenshot](../assets/img/getting-started/whoami-localhost.png)
+
+## Exposing the Application Using the Gateway API
+
+Traefik supports the Kubernetes Gateway API specification, which provides a more standardized way to configure ingress in Kubernetes.
+When we installed Traefik earlier, we enabled the Gateway API provider. 
+You can verify this in the providers section of the Traefik dashboard.
+
+![Providers Section Screenshot](../assets/img/getting-started/providers.png)
+
+To use the Gateway API:
+
+Install the Gateway API CRDs in your cluster:
+
+```bash
+kubectl apply -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.2.1/standard-install.yaml
+```
+
+Create an HTTPRoute. This configuration:
+
+- Creates an HTTPRoute named "whoami"
+- Attaches it to the default Gateway that Traefik created during installation
+- Configures routing for the hostname "whoami-gatewayapi.localhost"
+- Routes all traffic to the whoami service on port 80
+
+```yaml
+# httproute.yaml
+apiVersion: gateway.networking.k8s.io/v1
+kind: HTTPRoute
+metadata:
+  name: whoami
+spec:
+  parentRefs:
+    - name: traefik-gateway
+  hostnames:
+    - "whoami-gatewayapi.localhost"
+  rules:
+    - matches:
+        - path:
+            type: PathPrefix
+            value: /
+      backendRefs:
+        - name: whoami
+          port: 80
+```
+
+Apply the manifest:
+
+```bash
+kubectl apply -f httproute.yaml
+```
+
+### Test Your Setup
+
+You can use the following curl command to verify that the application is correctly exposed:
+
+```bash
+curl http://whoami-gatewayapi.localhost
+
+Hostname: whoami-76c9859cfc-6v8hh
+IP: 127.0.0.1
+IP: ::1
+IP: 10.42.0.11
+IP: fe80::20ad:eeff:fe44:a63
+RemoteAddr: 10.42.0.9:38280

+X-Forwarded-Proto: http
+X-Forwarded-Server: traefik-598946cd7-zds59
+X-Real-Ip: 127.0.0.1
+```
+
+You can now visit [http://whoami.localhost](http://whoami.localhost) in your browser to verify that the application is exposed correctly:
+
+![whoami application Screenshot](../assets/img/getting-started/whoami-localhost.png)
+
+If you navigate to the **HTTP Routes** section of the traefik dashboard, you can see that the `whoami.localhost` route is managed by the Traefik Kubernetes Gateway API provider:
+
+![Traefik Dashboard HTTP Routes Section Screenshot](../assets/img/getting-started/kubernetes-gateway.png)
+
+That's it! You've successfully deployed Traefik and configured routing in a Kubernetes cluster.

-# Quick Start
-
-A Use Case of Traefik Proxy and Kubernetes
-{: .subtitle }
-
-This guide is an introduction to using Traefik Proxy in a Kubernetes environment.  
-The objective is to learn how to run an application behind a Traefik reverse proxy in Kubernetes.  
-It presents and explains the basic blocks required to start with Traefik such as Ingress Controller, Ingresses, Deployments, static, and dynamic configuration.
-
-## Permissions and Accesses
-
-Traefik uses the Kubernetes API to discover running services.
-
-To use the Kubernetes API, Traefik needs some permissions.
-This [permission mechanism](https://kubernetes.io/docs/reference/access-authn-authz/rbac/) is based on roles defined by the cluster administrator.  
-The role is then bound to an account used by an application, in this case, Traefik Proxy.
-
-The first step is to create the role.
-The [`ClusterRole`](https://kubernetes.io/docs/reference/kubernetes-api/authorization-resources/cluster-role-v1/#ClusterRole) resource enumerates the resources and actions available for the role.
-In a file called `00-role.yml`, put the following `ClusterRole`:
-
-```yaml tab="00-role.yml"
-kind: ClusterRole
-apiVersion: rbac.authorization.k8s.io/v1
-metadata:
-  name: traefik-role
-
-rules:
-  - apiGroups:
-      - ""
-    resources:
-      - services
-      - endpoints
-      - secrets
-    verbs:
-      - get
-      - list
-      - watch
-  - apiGroups:
-      - extensions
-      - networking.k8s.io
-    resources:
-      - ingresses
-      - ingressclasses
-    verbs:
-      - get
-      - list
-      - watch
-  - apiGroups:
-      - extensions
-      - networking.k8s.io
-    resources:
-      - ingresses/status
-    verbs:
-      - update
-```
-
-!!! info "You can find the reference for this file [there](../../reference/dynamic-configuration/kubernetes-crd/#rbac)."
-
-The next step is to create a dedicated service account for Traefik.
-In a file called `00-account.yml`, put the following [`ServiceAccount`](https://kubernetes.io/docs/reference/kubernetes-api/authentication-resources/service-account-v1/#ServiceAccount) resource:
-
-```yaml tab="00-account.yml"
-apiVersion: v1
-kind: ServiceAccount
-metadata:
-  name: traefik-account
-```
-
-And then, bind the role on the account to apply the permissions and rules on the latter. In a file called `01-role-binding.yml`, put the
-following [`ClusterRoleBinding`](https://kubernetes.io/docs/reference/kubernetes-api/authorization-resources/cluster-role-binding-v1/#ClusterRoleBinding) resource:
-
-```yaml tab="01-role-binding.yml"
-kind: ClusterRoleBinding
-apiVersion: rbac.authorization.k8s.io/v1
-metadata:
-  name: traefik-role-binding
-
-roleRef:
-  apiGroup: rbac.authorization.k8s.io
-  kind: ClusterRole
-  name: traefik-role
-subjects:
-  - kind: ServiceAccount
-    name: traefik-account
-    namespace: default # This tutorial uses the "default" K8s namespace.
-```
-
-!!! info "`roleRef` is the Kubernetes reference to the role created in `00-role.yml`."
-
-!!! info "`subjects` is the list of accounts reference."
-
-    In this guide, it only contains the account created in `00-account.yml`
-
-## Deployment and Exposition
-
-!!! info "This section can be managed with the help of the [Traefik Helm chart](../install-traefik/#use-the-helm-chart)."
-
-The [ingress controller](https://traefik.io/glossary/kubernetes-ingress-and-ingress-controller-101/#what-is-a-kubernetes-ingress-controller)
-is a software that runs in the same way as any other application on a cluster.  
-To start Traefik on the Kubernetes cluster,
-a [`Deployment`](https://kubernetes.io/docs/reference/kubernetes-api/workload-resources/deployment-v1/) resource must exist to describe how to configure
-and scale containers horizontally to support larger workloads.
-
-Start by creating a file called `02-traefik.yml` and paste the following `Deployment` resource:
-
-```yaml tab="02-traefik.yml"
-kind: Deployment
-apiVersion: apps/v1
-metadata:
-  name: traefik-deployment
-  labels:
-    app: traefik
-
-spec:
-  replicas: 1
-  selector:
-    matchLabels:
-      app: traefik
-  template:
-    metadata:
-      labels:
-        app: traefik
-    spec:
-      serviceAccountName: traefik-account
-      containers:
-        - name: traefik
-          image: traefik:v2.11
-          args:
-            - --api.insecure
-            - --providers.kubernetesingress
-          ports:
-            - name: web
-              containerPort: 80
-            - name: dashboard
-              containerPort: 8080
-```
-
-The deployment contains an important attribute for customizing Traefik: `args`.  
-These arguments are the static configuration for Traefik.  
-From here, it is possible to enable the dashboard,
-configure entry points,
-select dynamic configuration providers,
-and [more](../reference/static-configuration/cli.md).
-
-In this deployment,
-the static configuration enables the Traefik dashboard,
-and uses Kubernetes native Ingress resources as router definitions to route incoming requests.
-
-!!! info "When there is no entry point in the static configuration"
-
-    Traefik creates a default one called `web` using the port `80` routing HTTP requests.
-
-!!! info "When enabling the [`api.insecure`](../../operations/api/#insecure) mode, Traefik exposes the dashboard on the port `8080`."
-
-A deployment manages scaling and then can create lots of containers, called [Pods](https://kubernetes.io/docs/concepts/workloads/pods/).
-Each Pod is configured following the `spec` field in the deployment.  
-Given that, a Deployment can run multiple Traefik Proxy Pods,
-a piece is required to forward the traffic to any of the instance:
-namely a [`Service`](https://kubernetes.io/docs/reference/kubernetes-api/service-resources/service-v1/#Service).  
-Create a file called `02-traefik-services.yml` and insert the two `Service` resources:
-
-```yaml tab="02-traefik-services.yml"
-apiVersion: v1
-kind: Service
-metadata:
-  name: traefik-dashboard-service
-
-spec:
-  type: LoadBalancer
-  ports:
-    - port: 8080
-      targetPort: dashboard
-  selector:
-    app: traefik
----
-apiVersion: v1
-kind: Service
-metadata:
-  name: traefik-web-service
-
-spec:
-  type: LoadBalancer
-  ports:
-    - targetPort: web
-      port: 80
-  selector:
-    app: traefik
-```
-
-!!! warning "It is possible to expose a service in different ways."
-
-    Depending on your working environment and use case, the `spec.type` might change.  
-    It is strongly recommended to understand the available [service types](https://kubernetes.io/docs/concepts/services-networking/service/#publishing-services-service-types) before proceeding to the next step.
-
-It is now time to apply those files on your cluster to start Traefik.
-
-```shell
-kubectl apply -f 00-role.yml \
-              -f 00-account.yml \
-              -f 01-role-binding.yml \
-              -f 02-traefik.yml \
-              -f 02-traefik-services.yml
-```
-
-## Proxying applications
-
-The only part still missing is the business application behind the reverse proxy.  
-For this guide, we use the example application [traefik/whoami](https://github.com/traefik/whoami),
-but the principles are applicable to any other application.
-
-The `whoami` application is an HTTP server running on port 80 which answers host-related information to the incoming requests.  
-As usual, start by creating a file called `03-whoami.yml` and paste the following `Deployment` resource:
-
-```yaml tab="03-whoami.yml"
-kind: Deployment
-apiVersion: apps/v1
-metadata:
-  name: whoami
-  labels:
-    app: whoami
-
-spec:
-  replicas: 1
-  selector:
-    matchLabels:
-      app: whoami
-  template:
-    metadata:
-      labels:
-        app: whoami
-    spec:
-      containers:
-        - name: whoami
-          image: traefik/whoami
-          ports:
-            - name: web
-              containerPort: 80
-```
-
-And continue by creating the following `Service` resource in a file called `03-whoami-services.yml`:
-
-```yaml tab="03-whoami-services.yml"
-apiVersion: v1
-kind: Service
-metadata:
-  name: whoami
-
-spec:
-  ports:
-    - name: web
-      port: 80
-      targetPort: web
-      
-  selector:
-    app: whoami
-```
-
-Thanks to the Kubernetes API,
-Traefik is notified when an Ingress resource is created, updated, or deleted.  
-This makes the process dynamic.  
-The ingresses are, in a way, the [dynamic configuration](../../providers/kubernetes-ingress/) for Traefik.
-
-!!! tip
-
-    Find more information on [ingress controller](https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/),
-    and [Ingress](https://kubernetes.io/docs/concepts/services-networking/ingress/) in the official Kubernetes documentation.
-
-Create a file called `04-whoami-ingress.yml` and insert the `Ingress` resource:
-
-```yaml tab="04-whoami-ingress.yml"
-apiVersion: networking.k8s.io/v1
-kind: Ingress
-metadata:
-  name: whoami-ingress
-spec:
-  rules:
-  - http:
-      paths:
-      - path: /
-        pathType: Prefix
-        backend:
-          service:
-            name: whoami
-            port:
-              name: web
-```
-
-This `Ingress` configures Traefik to redirect any incoming requests starting with `/` to the `whoami:80` service.
-
-At this point, all the configurations are ready.
-It is time to apply those new files:
-
-```shell
-kubectl apply -f 03-whoami.yml \
-              -f 03-whoami-services.yml \
-              -f 04-whoami-ingress.yml
-```
-
-Now you should be able to access the `whoami` application and the Traefik dashboard.
-Load the dashboard on a web browser: [`http://localhost:8080`](http://localhost:8080).
-
-And now access the `whoami` application:
-
-```shell
-curl -v http://localhost/
-```
-
-!!! question "Going further"
-
-    - [Filter the ingresses](../providers/kubernetes-ingress.md#ingressclass) to use with [IngressClass](https://kubernetes.io/docs/concepts/services-networking/ingress/#ingress-class)
-    - Use [IngressRoute CRD](../providers/kubernetes-crd.md)
-    - Protect [ingresses with TLS](../routing/providers/kubernetes-ingress.md#enabling-tls-via-annotations)

-# Quick Start
-
-A Use Case Using Docker
-{: .subtitle }
-
-![quickstart-diagram](../assets/img/quickstart-diagram.png)
-
-## Launch Traefik With the Docker Provider
-
-Create a `docker-compose.yml` file where you will define a `reverse-proxy` service that uses the official Traefik image:
-
-```yaml
-version: '3'
-
-services:
-  reverse-proxy:
-    # The official v2 Traefik docker image
-    image: traefik:v2.11
-    # Enables the web UI and tells Traefik to listen to docker
-    command: --api.insecure=true --providers.docker
-    ports:
-      # The HTTP port
-      - "80:80"
-      # The Web UI (enabled by --api.insecure=true)
-      - "8080:8080"
-    volumes:
-      # So that Traefik can listen to the Docker events
-      - /var/run/docker.sock:/var/run/docker.sock
-```
-
-**That's it. Now you can launch Traefik!**
-
-Start your `reverse-proxy` with the following command:
-
-```shell
-docker-compose up -d reverse-proxy
-```
-
-You can open a browser and go to `http://localhost:8080/api/rawdata` to see Traefik's API rawdata (you'll go back there once you have launched a service in step 2).
-
-## Traefik Detects New Services and Creates the Route for You
-
-Now that you have a Traefik instance up and running, you will deploy new services.
-
-Edit your `docker-compose.yml` file and add the following at the end of your file.
-
-```yaml
-version: '3'
-
-services:
-
-  ...
-
-  whoami:
-    # A container that exposes an API to show its IP address
-    image: traefik/whoami
-    labels:
-      - "traefik.http.routers.whoami.rule=Host(`whoami.docker.localhost`)"
-```
-
-The above defines `whoami`: a web service that outputs information about the machine it is deployed on (its IP address, host, and others).
-
-Start the `whoami` service with the following command:
-
-```shell
-docker-compose up -d whoami
-```
-
-Go back to your browser (`http://localhost:8080/api/rawdata`) and see that Traefik has automatically detected the new container and updated its own configuration.
-
-When Traefik detects new services, it creates the corresponding routes so you can call them ... _let's see!_  (Here, you're using curl)
-
-```shell
-curl -H Host:whoami.docker.localhost http://127.0.0.1
-```
-
-_Shows the following output:_
-
-```yaml
-Hostname: a656c8ddca6c
-IP: 172.27.0.3
-#...
-```
-
-## More Instances? Traefik Load Balances Them
-
-Run more instances of your `whoami` service with the following command:
-
-```shell
-docker-compose up -d --scale whoami=2
-```
-
-Go back to your browser (`http://localhost:8080/api/rawdata`) and see that Traefik has automatically detected the new instance of the container.
-
-Finally, see that Traefik load-balances between the two instances of your service by running the following command twice:
-
-```shell
-curl -H Host:whoami.docker.localhost http://127.0.0.1
-```
-
-The output will show alternatively one of the following:
-
-```yaml
-Hostname: a656c8ddca6c
-IP: 172.27.0.3
-#...
-```
-
-```yaml
-Hostname: s458f154e1f1
-IP: 172.27.0.4
-# ...
-```
-
-!!! question "Where to Go Next?"
-
-    Now that you have a basic understanding of how Traefik can automatically create the routes to your services and load balance them, it is time to dive into [the documentation](/) and let Traefik work for you!

+# OCSP
+
+Check certificate status and perform OCSP stapling.
+{: .subtitle }
+
+## Overview
+
+### OCSP Stapling
+
+When OCSP is enabled, Traefik checks the status of every certificate in the store that provides an OCSP responder URL,
+including the default certificate, and staples the OCSP response to the TLS handshake.
+The OCSP check is performed when the certificate is loaded,
+and once every hour until it is successful at the halfway point before the update date.
+
+### Caching
+
+Traefik caches the OCSP response as long as the associated certificate is provided by the configuration.
+When a certificate is no longer provided,
+the OCSP response has a 24 hour TTL waiting to be provided again or eventually removed.
+The OCSP response is cached in memory and is not persisted between Traefik restarts.
+
+## Configuration
+
+### General
+
+Enabling OCSP is part of the [static configuration](../getting-started/configuration-overview.md#the-static-configuration).
+It can be defined by using a file (YAML or TOML) or CLI arguments:
+
+```yaml tab="File (YAML)"
+## Static configuration
+ocsp: {}
+```
+
+```toml tab="File (TOML)"
+## Static configuration
+[ocsp]
+```
+
+```bash tab="CLI"
+## Static configuration
+--ocsp=true
+```
+
+### Responder Overrides
+
+The `responderOverrides` option defines the OCSP responder URLs to use instead of the one provided by the certificate.
+This is useful when you want to use a different OCSP responder.
+
+```yaml tab="File (YAML)"
+## Static configuration
+ocsp:
+  responderOverrides:
+    foo: bar
+```
+
+```toml tab="File (TOML)"

+{: .subtitle }
+
+[SPIFFE](https://spiffe.io/docs/latest/spiffe-about/overview/) (Secure Production Identity Framework For Everyone), 
+provides a secure identity in the form of a specially crafted X.509 certificate, 
+to every workload in an environment.
+
+Traefik is able to connect to the Workload API to obtain an x509-SVID used to secure the connection with SPIFFE enabled backends.
+
+## Configuration
+
+### General
+
+Enabling SPIFFE is part of the [static configuration](../getting-started/configuration-overview.md#the-static-configuration).
+It can be defined by using a file (YAML or TOML) or CLI arguments.
+
+### Workload API
+
+The `workloadAPIAddr` configuration defines the address of the SPIFFE [Workload API](https://spiffe.io/docs/latest/spiffe-about/spiffe-concepts/#spiffe-workload-api).
+
+!!! info "Enabling SPIFFE in ServersTransports"
+
+    Enabling SPIFFE does not imply that backend connections are going to use it automatically.
+    Each [ServersTransport](../routing/services/index.md#serverstransport_1) or [TCPServersTransport](../routing/services/index.md#serverstransport_2),
+	that is meant to be secured with SPIFFE,
+	must explicitly enable it (see [SPIFFE with ServersTransport](../routing/services/index.md#spiffe) or [SPIFFE with TCPServersTransport](../routing/services/index.md#spiffe_1)).
+
+!!! warning "SPIFFE can cause Traefik to stall"
+	When using SPIFFE,
+	Traefik will wait for the first SVID to be delivered before starting.
+	If Traefik is hanging when waiting on SPIFFE SVID delivery,
+	please double check that it is correctly registered as workload in your SPIFFE infrastructure.

+Provision TLS certificates for your internal Tailscale services.
+{: .subtitle }
+
+To protect a service with TLS, a certificate from a public Certificate Authority is needed.
+In addition to its vpn role, Tailscale can also [provide certificates](https://tailscale.com/kb/1153/enabling-https/) for the machines in your Tailscale network.
+
+## Certificate resolvers
+
+To obtain a TLS certificate from the Tailscale daemon,
+a Tailscale certificate resolver needs to be configured as below.
+
+!!! info "Referencing a certificate resolver"
+
+    Defining a certificate resolver does not imply that routers are going to use it automatically.
+    Each router or entrypoint that is meant to use the resolver must explicitly [reference](../routing/routers/index.md#certresolver) it.

+certificatesResolvers:
+    myresolver:

+```
+
+```bash tab="CLI"
+--certificatesresolvers.myresolver.tailscale=true
+```
+
+## Domain Definition
+
+A certificate resolver requests certificates for a set of domain names inferred from routers, according to the following:
+
+- If the router has a [`tls.domains`](../routing/routers/index.md#domains) option set,
+  then the certificate resolver derives this router domain name from the `main` option of `tls.domains`.
+
+- Otherwise, the certificate resolver derives the domain name from any `Host()` or `HostSNI()` matchers
+  in the [router's rule](../routing/routers/index.md#rule).
+
+!!! info "Tailscale Domain Format"
+
+    The domain is only taken into account if it is a Tailscale-specific one,
+    i.e. of the form `machine-name.domains-alias.ts.net`.

-# Welcome
+# What is Traefik?
 
 ![Architecture](assets/img/traefik-architecture.png)
 
-Traefik is an [open-source](https://github.com/traefik/traefik) *Edge Router* that makes publishing your services a fun and easy experience. 
-It receives requests on behalf of your system and finds out which components are responsible for handling them. 
+Traefik is an [open-source](https://github.com/traefik/traefik) Application Proxy and the core of the Traefik Hub Runtime Platform.
 
-What sets Traefik apart, besides its many features, is that it automatically discovers the right configuration for your services. 
-The magic happens when Traefik inspects your infrastructure, where it finds relevant information and discovers which service serves which request. 
+If you start with Traefik for service discovery and routing, you can seamlessly add [API management](https://traefik.io/solutions/api-management/), [API gateway](https://traefik.io/solutions/api-gateway/), [AI gateway](https://traefik.io/solutions/ai-gateway/), and [API mocking](https://traefik.io/solutions/api-mocking/) capabilities as needed.
 
-Traefik is natively compliant with every major cluster technology, such as Kubernetes, Docker, Docker Swarm, AWS, Mesos, Marathon, and [the list goes on](providers/overview.md); and can handle many at the same time. (It even works for legacy software running on bare metal.)
+With 3.3 billion downloads and over 55k stars on GitHub, Traefik is used globally across hybrid cloud, multi-cloud, on prem, and bare metal environments running Kuberentes, Docker Swarm, AWS, [the list goes on](https://doc.traefik.io/traefik/reference/install-configuration/providers/overview/).
 
-With Traefik, there is no need to maintain and synchronize a separate configuration file: everything happens automatically, in real time (no restarts, no connection interruptions).
-With Traefik, you spend time developing and deploying new features to your system, not on configuring and maintaining its working state.   
+Here’s how it works—Traefik receives requests on behalf of your system, identifies which components are responsible for handling them, and routes them securely. It automatically discovers the right configuration for your services by inspecting your infrastructure to identify relevant information and which service serves which request.
 
-Developing Traefik, our main goal is to make it effortless to use, and we're sure you'll enjoy it.
+Because everything happens automatically, in real time (no restarts, no connection interruptions), you can focus on developing and deploying new features to your system, instead of configuring and maintaining its working state.
 
--- The Traefik Maintainer Team 
+!!! quote "From the Traefik Maintainer Team" 
+    When developing Traefik, our main goal is to make it easy to use, and we're sure you'll enjoy it.
+
+## Personas
+
+Traefik supports different needs depending on your background. We keep three user personas in mind as we build and organize these docs:
+
+- **Beginners**: You are new to Traefik or new to reverse proxies. You want simple, guided steps to set things up without diving too deep into advanced topics.
+- **DevOps Engineers**: You manage infrastructure or clusters (Docker, Kubernetes, or other orchestrators). You integrate Traefik into your environment and value reliability, performance, and streamlined deployments.
+- **Developers**: You create and deploy applications or APIs. You focus on how to expose your services through Traefik, apply routing rules, and integrate it with your development workflow.
+
+## Core Concepts
+
+Traefik’s main concepts help you understand how requests flow to your services:
+
+- [Entrypoints](./reference/install-configuration/entrypoints.md) are the network entry points into Traefik. They define the port that will receive the packets and whether to listen for TCP or UDP.
+- [Routers](./reference/routing-configuration/http/router/rules-and-priority.md) are in charge of connecting incoming requests to the services that can handle them. In the process, routers may use pieces of [middleware](./reference/routing-configuration/http/middlewares/overview.md) to update the request or act before forwarding the request to the service.
+- [Services](./reference/routing-configuration/http/load-balancing/service.md) are responsible for configuring how to reach the actual services that will eventually handle the incoming requests.
+- [Providers](./reference/install-configuration/providers/overview.md) are infrastructure components, whether orchestrators, container engines, cloud providers, or key-value stores. The idea is that Traefik queries the provider APIs in order to find relevant information about routing, and when Traefik detects a change, it dynamically updates the routes.
+
+These concepts work together to manage your traffic from the moment a request arrives until it reaches your application.
+
+## How to Use the Documentation
+
+- **Navigation**: Each main section focuses on a specific stage of working with Traefik - installing, exposing services, observing, extending & migrating. 
+Use the sidebar to navigate to the section that is most appropriate for your needs.
+- **Practical Examples**: You will see code snippets and configuration examples for different environments (YAML/TOML, Labels, & Tags).
+- **Reference**: When you need to look up technical details, our reference section provides a deep dive into configuration options and key terms.

 Handling Content-Type auto-detection

-The Content-Type middleware - or rather its `autoDetect` option -
-specifies whether to let the `Content-Type` header,
-if it has not been defined by the backend,
-be automatically set to a value derived from the contents of the response.
-
-As a proxy, the default behavior should be to leave the header alone,
-regardless of what the backend did with it.
-However, the historic default was to always auto-detect and set the header if it was not already defined,
-and altering this behavior would be a breaking change which would impact many users.
-
-This middleware exists to enable the correct behavior until at least the default one can be changed in a future version.
+The Content-Type middleware sets the `Content-Type` header value to the media type detected from the response content,
+when it is not set by the backend.
 
 !!! info
 
-    As explained above, for compatibility reasons the default behavior on a router (without this middleware),
-    is still to automatically set the `Content-Type` header.
-    Therefore, given the default value of the `autoDetect` option (false),
-    simply enabling this middleware for a router switches the router's behavior.
-
     The scope of the Content-Type middleware is the MIME type detection done by the core of Traefik (the server part).
     Therefore, it has no effect against any other `Content-Type` header modifications (e.g.: in another middleware such as compress).

+Converting gRPC Web requests to HTTP/2 gRPC requests.
+{: .subtitle }
+
+The GrpcWeb middleware converts gRPC Web requests to HTTP/2 gRPC requests before forwarding them to the backends.
+
+!!! tip
+
+    Please note, that Traefik needs to communicate using gRPC with the backends (h2c or HTTP/2 over TLS).
+    Check out the [gRPC](../../user-guides/grpc.md) user guide for more details.
