 ## Overview
 
-Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services.
-If you want your users to access some of your microservices from the Internet, you will have to use a reverse proxy and configure it using virtual hosts or prefix paths:
+Imagine that you have deployed a bunch of microservices with the help of an orchestrator (like Swarm or Kubernetes) or a service registry (like etcd or consul).
+Now you want users to access these microservices, and you need a reverse proxy.
 
-- domain `api.domain.com` will point the microservice `api` in your private network
-- path `domain.com/web` will point the microservice `web` in your private network
-- domain `backoffice.domain.com` will point the microservices `backoffice` in your private network, load-balancing between your multiple instances
+Traditional reverse-proxies require that you configure _each_ route that will connect paths and subdomains to _each_ microservice. 
+In an environment where you add, remove, kill, upgrade, or scale your services _many_ times a day, the task of keeping the routes up to date becomes tedious. 
 
-Microservices are often deployed in dynamic environments where services are added, removed, killed, upgraded or scaled many times a day.
+**This is when Træfik can help you!**
 
-Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.
+Træfik listens to your service registry/orchestrator API and instantly generates the routes so your microservices are connected to the outside world -- without further intervention from your part. 
 
-Here enters Træfik.
+**Run Træfik and let it do the work for you!** 
+_(But if you'd rather configure some of your routes manually, Træfik supports that too!)_
 
 ![Architecture](docs/img/architecture.png)
 
-Træfik can listen to your service registry/orchestrator API, and knows each time a microservice is added, removed, killed or upgraded, and can generate its configuration automatically.
-Routes to your services will be created instantly.
-
-Run it and forget it!

-- The simple way: grab the latest binary from the [releases](https://github.com/containous/traefik/releases) page and just run it with the [sample configuration file](https://raw.githubusercontent.com/containous/traefik/master/traefik.sample.toml):
-
-```shell
-./traefik --configFile=traefik.toml
-```
-
-- Use the tiny Docker image and just run it with the [sample configuration file](https://raw.githubusercontent.com/containous/traefik/master/traefik.sample.toml):
-
-```shell
-docker run -d -p 8080:8080 -p 80:80 -v $PWD/traefik.toml:/etc/traefik/traefik.toml traefik

-## Release cycle
-
-- Release: We try to release a new version every 2 months
-  - i.e.: 1.3.0, 1.4.0, 1.5.0
-- Release candidate: we do RC (1.**x**.0-rc**y**) before the final release (1.**x**.0)
-  - i.e.: 1.1.0-rc1 -> 1.1.0-rc2 -> 1.1.0-rc3 -> 1.1.0-rc4 -> 1.1.0
-- Bug-fixes: For each version we release bug fixes
-  - i.e.: 1.1.1, 1.1.2, 1.1.3
-  - those versions contain only bug-fixes
-  - no additional features are delivered in those versions
-- Each version is supported until the next one is released
-  - i.e.: 1.1.x will be supported until 1.2.0 is out
-- We use [Semantic Versioning](http://semver.org/)

+## Wildcard certificates
+
+[ACME V2](https://community.letsencrypt.org/t/acme-v2-and-wildcard-certificate-support-is-live/55579) allows wildcard certificate support.
+However, this feature needs a specific configuration.
+
+### DNS-01 Challenge
+
+As described in [Let's Encrypt post](https://community.letsencrypt.org/t/staging-endpoint-for-acme-v2/49605), wildcard certificates can only be generated through a `DNS-01` Challenge.
+This challenge is linked to the Træfik option `acme.dnsChallenge`.
+
+```toml
+[acme]
+# ...
+[acme.dnsChallenge]
+  provider = "digitalocean"
+  delayBeforeCheck = 0
+# ...
+```
+
+For more information about this option, please refer to the [dnsChallenge section](/configuration/acme/#dnschallenge).
+
+### Wildcard domain
+
+Wildcard domains can currently be provided only by to the `acme.domains` option.
+
+```toml
+[acme]
+# ...
+[[acme.domains]]
+  main = "*.local1.com"
+  sans = ["local1.com"]
+[[acme.domains]]
+  main = "*.local2.com"
+# ...
+```
+
+For more information about this option, please refer to the [domains section](/configuration/acme/#domains).
+
+### Limitations
+
+Let's Encrypt wildcard support have some limitations to take into account :
+
+- Wildcard domain can not be a SAN (alternative domain),
+- Wildcard domain on a wildcard domain is forbidden (for example `*.*.local.com`),
+- A DNS-01 Challenge is executed for each domain (CN and SANs), DNS provider can not manage correctly this behavior as explained in the [DNS provider support section](/configuration/acme/#dns-provider-support)
+
+
+### DNS provider support
+
+All DNS providers allow creating ACME wildcard certificates.
+However, many troubles can appear for wildcard domains with SANs.
+
+If a wildcard domain is defined with it root domain as SAN, as described below, 2 DNS-01 Challenges will be executed.
+
+```toml
+[acme]
+# ...
+[[acme.domains]]
+  main = "*.local1.com"
+  sans = ["local1.com"]
+# ...
+```
+
+When a DNS-01 Challenge is done, Let's Encrypt checks if a TXT record is created with a given name and a given value.
+When a certificate is generated for a wildcard domain is defined with it root domain as SAN, the requested TXT record name for both the wildcard domain and the root domain is the same.
+
+The [DNS RFC](https://community.letsencrypt.org/t/wildcard-issuance-two-txt-records-for-the-same-name/54528/2) allows this behavior.
+But all DNS providers keep TXT records values in a cache with a TTL.
+In function of the parameters given by the Træfik ACME client library ([LEGO](https://github.com/xenolf/lego)), the TXT record TTL can be superior to challenge Timeout.
+In that event, the DNS-01 Challenge will not work correctly.
+ 
+[LEGO](https://github.com/xenolf/lego) will involve in the way to be adapted to all of DNS providers.
+Meanwhile, the table described below contains all the DNS providers supported by Træfik and indicates if they allow generating certificates for a wildcard domain and its root domain.
+Do not hesitate to complete it.

+## ACME V2 migration
+
+During migration from ACME V1 to ACME V2 with a storage file, a backup is created with the content of the ACME V1 file.
+To obtain the name of the backup file, Træfik concatenates the option `acme.storage` and the suffix `.bak`.
+
+For example : if `acme.storage` value is `/etc/traefik/acme/acme.json`, the backup file will be named `/etc/traefik/acme/acme.json.bak`.
+
+!!! note
+    When Træfik is launched in a container, do not forget to create a volume of the parent folder to get the backup file on the host.
+    Otherwise, the backup file will be deleted when the container will be stopped and Træfik will not generate it again.

 ### Examples
 
 If you want that Træfik uses Consul tags correctly you need to defined them like that:
-```json
+
+```js
 traefik.enable=true
 traefik.tags=api
 traefik.tags=external
 ```
 
 If the prefix defined in Træfik configuration is `bla`, tags need to be defined like that:
-```json
+
+```js
 bla.enable=true
 bla.tags=api
 bla.tags=external
-```
+```

+[1] `traefik.docker.network`:
+If a container is linked to several networks, be sure to set the proper network name (you can check with `docker inspect <container_id>`) otherwise it will randomly pick one (depending on how docker is returning them).
+For instance when deploying docker `stack` from compose files, the compose defined networks will be prefixed with the `stack` name.
+Or if your service references external network use it's name instead.

-### On Service
+### On containers with Multiple Ports (segment labels)
 
-Services labels can be used for overriding default behaviour
+Segment labels are used to define routes to a container exposing multiple ports.
+A segment is a group of labels that apply to a port exposed by a container.
+You can define as many segments as ports exposed in a container.
+
+Segment labels override the default behavior.

 ## Annotations
 
 ### General annotations
 
 The following general annotations are applicable on the Ingress object:
 
-- `traefik.frontend.rule.type: PathPrefixStrip`
-    Override the default frontend rule type. Default: `PathPrefix`.
-- `traefik.frontend.priority: "3"`
-    Override the default frontend rule priority.
-- `traefik.frontend.redirect.entryPoint: https`:
-    Enables Redirect to another entryPoint for that frontend (e.g. HTTPS).
-- `traefik.frontend.redirect.regex: ^http://localhost/(.*)`:
-    Redirect to another URL for that frontend. Must be set with `traefik.frontend.redirect.replacement`.
-- `traefik.frontend.redirect.replacement: http://mydomain/$1`:
-    Redirect to another URL for that frontend. Must be set with `traefik.frontend.redirect.regex`.
-- `traefik.frontend.entryPoints: http,https`
-    Override the default frontend endpoints.
-- `traefik.frontend.passTLSCert: true`
-    Override the default frontend PassTLSCert value. Default: `false`.
-- `ingress.kubernetes.io/rewrite-target: /users`
-    Replaces each matched Ingress path with the specified one, and adds the old path to the `X-Replaced-Path` header.
-- `ingress.kubernetes.io/whitelist-source-range: "1.2.3.0/24, fe80::/16"`
-    A comma-separated list of IP ranges permitted for access. all source IPs are permitted if the list is empty or a single range is ill-formatted.

 ### Authentication
 
 Is possible to add additional authentication annotations to the Ingress object.
 The source of the authentication is a Secret object that contains the credentials.
 
-- `ingress.kubernetes.io/auth-type`: `basic`
-    Contains the authentication type. The only permitted type is `basic`.
-- `ingress.kubernetes.io/auth-secret`: `mysecret`
-    Contains the username and password with access to the paths defined in the Ingress object.

+### Applications with Multiple Ports (segment labels)
+
+Segment labels are used to define routes to an application exposing multiple ports.
+A segment is a group of labels that apply to a port exposed by an application.
+You can define as many segments as ports exposed in an application.
+
+Segment labels override the default behavior.

+### On containers with Multiple Ports (segment labels)
+
+Segment labels are used to define routes to a container exposing multiple ports.
+A segment is a group of labels that apply to a port exposed by a container.
+You can define as many segments as ports exposed in a container.
+
+Segment labels override the default behavior.

-### Log Rotation
-
-Traefik will close and reopen its log files, assuming they're configured, on receipt of a USR1 signal.
-This allows the logs to be rotated and processed by an external program, such as `logrotate`.
-
-!!! note
-    This does not work on Windows due to the lack of USR signals.

+By enabling this, Træfik will read the entire request into memory (possibly buffering large requests into disk) and will reject requests that are over a specified limit.

+## Traefik Logs
+
+By default the Traefik log is written to stdout in text format.
+
+To write the logs into a log file specify the `filePath`:
+```toml
+[traefikLog]
+  filePath = "/path/to/traefik.log"
+```
+
+To write JSON format logs, specify `json` as the format:
+```toml
+[traefikLog]
+  filePath = "/path/to/traefik.log"
+  format   = "json"
+```
+
+
+Deprecated way (before 1.4):
+
+!!! danger "DEPRECATED"
+    `traefikLogsFile` is deprecated, use [traefikLog](/configuration/logs/#traefik-logs) instead.
+
+```toml
+# Traefik logs file
+# If not defined, logs to stdout
+#
+# DEPRECATED - see [traefikLog] lower down
+# In case both traefikLogsFile and traefikLog.filePath are specified, the latter will take precedence.
+# Optional
+#
+traefikLogsFile = "log/traefik.log"
+```
+
+To customize the log level:
+```toml
+# Log level
+#
+# Optional
+# Default: "ERROR"
+#
+# Accepted values, in order of severity: "DEBUG", "INFO", "WARN", "ERROR", "FATAL", "PANIC"
+# Messages at and above the selected level will be logged.
+#
+logLevel = "ERROR"
+```
+
+
+## Access Logs
+
+Access logs are written when `[accessLog]` is defined.
+By default it will write to stdout and produce logs in the textual Common Log Format (CLF), extended with additional fields.
+
+To enable access logs using the default settings just add the `[accessLog]` entry:
+```toml
+[accessLog]
+```
+
+To write the logs into a log file specify the `filePath`:
+```toml
+[accessLog]
+filePath = "/path/to/access.log"
+```
+
+To write JSON format logs, specify `json` as the format:
+```toml
+[accessLog]
+filePath = "/path/to/access.log"
+format = "json"
+```
+
+To filter logs you can specify a set of filters which are logically "OR-connected". Thus, specifying multiple filters will keep more access logs than specifying only one:
+```toml
+[accessLog]
+filePath = "/path/to/access.log"
+format = "json"
+
+  [accessLog.filters]
+
+  # statusCodes keep access logs with status codes in the specified range
+  #
+  # Optional
+  # Default: []
+  #
+  statusCodes = ["200", "300-302"]
+
+  # retryAttempts keep access logs when at least one retry happened
+  #
+  # Optional
+  # Default: false
+  #
+  retryAttempts = true
+```
+
+To customize logs format:
+```toml
+[accessLog]
+filePath = "/path/to/access.log"
+format = "json"
+
+  [accessLog.filters]
+
+  # statusCodes keep only access logs with status codes in the specified range

+## Log Rotation
+
+Traefik will close and reopen its log files, assuming they're configured, on receipt of a USR1 signal.
+This allows the logs to be rotated and processed by an external program, such as `logrotate`.
+
+!!! note
+    This does not work on Windows due to the lack of USR signals.

-Træfik (pronounced like _traffic_) is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease.
-It supports several backends ([Docker](https://www.docker.com/), [Swarm mode](https://docs.docker.com/engine/swarm/), [Kubernetes](https://kubernetes.io), [Marathon](https://mesosphere.github.io/marathon/), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Rancher](https://rancher.com), [Amazon ECS](https://aws.amazon.com/ecs), and a lot more) to manage its configuration automatically and dynamically.
+Træfik is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy.
+Træfik integrates with your existing infrastructure components ([Docker](https://www.docker.com/), [Swarm mode](https://docs.docker.com/engine/swarm/), [Kubernetes](https://kubernetes.io), [Marathon](https://mesosphere.github.io/marathon/), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Rancher](https://rancher.com), [Amazon ECS](https://aws.amazon.com/ecs), ...) and configures itself automatically and dynamically.
+Telling Træfik where your orchestrator is could be the _only_ configuration step you need to do.
 
 ## Overview
 
-Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services.
-If you want your users to access some of your microservices from the Internet, you will have to use a reverse proxy and configure it using virtual hosts or prefix paths:
+Imagine that you have deployed a bunch of microservices with the help of an orchestrator (like Swarm or Kubernetes) or a service registry (like etcd or consul).
+Now you want users to access these microservices, and you need a reverse proxy.
 
-- domain `api.domain.com` will point the microservice `api` in your private network
-- path `domain.com/web` will point the microservice `web` in your private network
-- domain `backoffice.domain.com` will point the microservices `backoffice` in your private network, load-balancing between your multiple instances
+Traditional reverse-proxies require that you configure _each_ route that will connect paths and subdomains to _each_ microservice. In an environment where you add, remove, kill, upgrade, or scale your services _many_ times a day, the task of keeping the routes up to date becomes tedious. 
 
-Microservices are often deployed in dynamic environments where services are added, removed, killed, upgraded or scaled many times a day.
+**This is when Træfik can help you!**
 
-Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.
+Træfik listens to your service registry/orchestrator API and instantly generates the routes so your microservices are connected to the outside world -- without further intervention from your part. 
 
-Here enters Træfik.
+**Run Træfik and let it do the work for you!** 
+_(But if you'd rather configure some of your routes manually, Træfik supports that too!)_
 
 ![Architecture](img/architecture.png)
 
-Træfik can listen to your service registry/orchestrator API, and knows each time a microservice is added, removed, killed or upgraded, and can generate its configuration automatically.
-Routes to your services will be created instantly.
-
-Run it and forget it!

+## The Træfik Quickstart (Using Docker)
 
-## Quickstart
+In this quickstart, we'll use [Docker compose](https://docs.docker.com/compose) to create our demo infrastructure.
 
-You can have a quick look at Træfik in this [Katacoda tutorial](https://www.katacoda.com/courses/traefik/deploy-load-balancer) that shows how to load balance requests between multiple Docker containers.
+To save some time, you can clone [Træfik's repository](https://github.com/containous/traefik) and use the quickstart files located in the [examples/quickstart](https://github.com/containous/traefik/tree/master/examples/quickstart/) directory.
+
+### 1 — Launch Træfik — Tell It to Listen to Docker
+
+Create a `docker-compose.yml` file where you will define a `reverse-proxy` service that uses the official Træfik image:
+
+```yaml
+version: '3'
+
+services:
+  reverse-proxy:
+    image: traefik #The official Traefik docker image
+    command: --api --docker #Enables the web UI and tells Træfik to listen to docker
+    ports:
+      - "80:80"     #The HTTP port
+      - "8080:8080" #The Web UI (enabled by --api)
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock #So that Traefik can listen to the Docker events
+```
+
+**That's it. Now you can launch Træfik!**
+
+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](http://localhost:8080) to see Træfik's dashboard (we'll go back there once we have launched a service in step 2).
+
+### 2 — Launch a Service — Træfik Detects It and Creates a Route for You 
+
+Now that we have a Træfik instance up and running, we will deploy new services. 
+
+Edit your `docker-compose.yml` file and add the following at the end of your file. 
+
+```yaml
+# ... 
+  whoami:
+    image: emilevauge/whoami #A container that exposes an API to show it's IP address
+    labels:
+      - "traefik.frontend.rule=Host:whoami.docker.localhost"
+```
+
+The above defines `whoami`: a simple web service that outputs information about the machine it is deployed on (its IP address, host, and so on).
+
+Start the `whoami` service with the following command:
+ 
+```shell
+docker-compose up -d whoami
+```
+
+Go back to your browser ([http://localhost:8080](http://localhost:8080)) and see that Træfik 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, we're using curl)
+
+```shell
+curl -H Host:whoami.docker.localhost http://127.0.0.1
+```
+
+_Shows the following output:_
+```yaml
+Hostname: 8656c8ddca6c
+IP: 172.27.0.3
+#...
+```
+
+### 3 — Launch 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](http://localhost:8080)) and see that Træfik has automatically detected the new instance of the container.
+
+Finally, see that Træfik load-balances between the two instances of your services by running twice the following command:
+
+```shell
+curl -H Host:whoami.docker.localhost http://127.0.0.1
+```
+
+The output will show alternatively one of the followings:
+
+```yaml
+Hostname: 8656c8ddca6c
+IP: 172.27.0.3
+#...
+```
+
+```yaml
+Hostname: 8458f154e1f1
+IP: 172.27.0.4
+# ...
+```
+
+### 4 — Enjoy Træfik's Magic
+
+Now that you have a basic understanding of how Træfik can automatically create the routes to your services and load balance them, it might be time to dive into [the documentation](https://docs.traefik.io/) and let Træfik work for you! Whatever your infrastructure is, there is probably [an available Træfik backend](https://docs.traefik.io/configuration/backends/available) that will do the job. 
+
+Our recommendation would be to see for yourself how simple it is to enable HTTPS with [Træfik's let's encrypt integration](https://docs.traefik.io/user-guide/examples/#lets-encrypt-support) using the dedicated [user guide](https://docs.traefik.io/user-guide/docker-and-lets-encrypt/).

+### Add a TLS Certificate to the Ingress
+
+!!! note
+    For this example to work you need a TLS entrypoint. You don't have to provide a TLS certificate at this point. For more details see [here](/configuration/entrypoints/).
+
+To setup an HTTPS-protected ingress, you can leverage the TLS feature of the ingress resource.
+
+```yaml
+apiVersion: extensions/v1beta1
+kind: Ingress
+metadata:
+  name: traefik-web-ui
+  namespace: kube-system
+  annotations:
+    kubernetes.io/ingress.class: traefik
+spec:
+  rules:
+  - host: traefik-ui.minikube
+    http:
+      paths:
+      - backend:
+          serviceName: traefik-web-ui
+          servicePort: 80
+  tls:
+   - secretName: traefik-ui-tls-cert
+```
+
+In addition to the modified ingress you need to provide the TLS certificate via a Kubernetes secret in the same namespace as the ingress. The following two commands will generate a new certificate and create a secret containing the key and cert files.
+
+```shell
+openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj "/CN=traefik-ui.minikube"
+kubectl -n kube-system create secret tls traefik-ui-tls-cert --key=tls.key --cert=tls.crt
+```
+
+If there are any errors while loading the TLS section of an ingress, the whole ingress will be skipped.
+
+!!! note
+    The secret must have two entries named `tls.key`and `tls.crt`. See the [Kubernetes documentation](https://kubernetes.io/docs/concepts/services-networking/ingress/#tls) for more details.
+
+!!! note
+    The TLS certificates will be added to all entrypoints defined by the ingress annotation `traefik.frontend.entryPoints`. If no such annotation is provided, the TLS certificates will be added to all TLS-enabled `defaultEntryPoints`.
+
+!!! note
+    The field `hosts` in the TLS configuration is ignored. Instead, the domains provided by the certificate are used for this purpose. It is recommended to not use wildcard certificates as they will match globally.

+## The Træfik Quickstart (Using Docker)
+
+In this quickstart, we'll use [Docker compose](https://docs.docker.com/compose) to create our demo infrastructure.
+
+To save some time, you can clone [Træfik's repository](https://github.com/containous/traefik) and use the quickstart files located in the [examples/quickstart](https://github.com/containous/traefik/tree/master/examples/quickstart/) directory.
+
+### 1 — Launch Træfik — Tell It to Listen to Docker
+
+Create a `docker-compose.yml` file where you will define a `reverse-proxy` service that uses the official Træfik image:
+
+```yaml
+version: '3'
+
+services:
+  reverse-proxy:
+    image: traefik #The official Traefik docker image
+    command: --api --docker #Enables the web UI and tells Træfik to listen to docker
+    ports:
+      - "80:80"     #The HTTP port
+      - "8080:8080" #The Web UI (enabled by --api)
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock #So that Traefik can listen to the Docker events
+```
+
+**That's it. Now you can launch Træfik!**
+
+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](http://localhost:8080) to see Træfik's dashboard (we'll go back there once we have launched a service in step 2).
+
+### 2 — Launch a Service — Træfik Detects It and Creates a Route for You 
+
+Now that we have a Træfik instance up and running, we will deploy new services. 
+
+Edit your `docker-compose.yml` file and add the following at the end of your file. 
+
+```yaml
+# ... 
+  whoami:
+    image: emilevauge/whoami #A container that exposes an API to show it's IP address
+    labels:
+      - "traefik.frontend.rule=Host:whoami.docker.localhost"
+```
+
+The above defines `whoami`: a simple web service that outputs information about the machine it is deployed on (its IP address, host, and so on).
+
+Start the `whoami` service with the following command:
+ 
+```shell
+docker-compose up -d whoami
+```
+
+Go back to your browser ([http://localhost:8080](http://localhost:8080)) and see that Træfik 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, we're using curl)
+
+```shell
+curl -H Host:whoami.docker.localhost http://127.0.0.1
+```
+
+_Shows the following output:_
+```yaml
+Hostname: 8656c8ddca6c
+IP: 172.27.0.3
+#...
+```
+
+### 3 — Launch 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](http://localhost:8080)) and see that Træfik has automatically detected the new instance of the container.
+
+Finally, see that Træfik load-balances between the two instances of your services by running twice the following command:
+
+```shell
+curl -H Host:whoami.docker.localhost http://127.0.0.1
+```
+
+The output will show alternatively one of the followings:
+
+```yaml
+Hostname: 8656c8ddca6c
+IP: 172.27.0.3
+#...
+```
+
+```yaml
+Hostname: 8458f154e1f1
+IP: 172.27.0.4
+# ...
+```
+
+### 4 — Enjoy Træfik's Magic
+
+Now that you have a basic understanding of how Træfik can automatically create the routes to your services and load balance them, it might be time to dive into [the documentation](https://docs.traefik.io/) and let Træfik work for you! Whatever your infrastructure is, there is probably [an available Træfik backend](https://docs.traefik.io/configuration/backends/available) that will do the job. 
+
+Our recommendation would be to see for yourself how simple it is to enable HTTPS with [Træfik's let's encrypt integration](https://docs.traefik.io/user-guide/examples/#lets-encrypt-support) using the dedicated [user guide](https://docs.traefik.io/user-guide/docker-and-lets-encrypt/).
