 ## Use the Helm Chart

-!!! warning "Experimental Helm Chart"
+!!! warning
    
-    Please note that the Helm Chart for Traefik v2 is still experimental.
-    
-    The Traefik Stable Chart from 
+    The Traefik Chart from 
    [Helm's default charts repository](https://github.com/helm/charts/tree/master/stable/traefik) is still using [Traefik v1.7](https://docs.traefik.io/v1.7).

-Traefik can be installed in Kubernetes using the v2.0 Helm chart from <https://github.com/containous/traefik-helm-chart>.
+Traefik can be installed in Kubernetes using the Helm chart from <https://github.com/containous/traefik-helm-chart>.

 Ensure that the following requirements are met:

 * Kubernetes 1.14+
-* Helm version 2.x is [installed](https://v2.helm.sh/docs/using_helm/) and initialized with Tiller
+* Helm version 3.x is [installed](https://helm.sh/docs/intro/install/)

-Retrieve the latest chart version from the repository:
+Add Traefik's chart repository to Helm:

 ```bash
-# Retrieve Chart from the repository
-git clone https://github.com/containous/traefik-helm-chart
+helm repo add traefik https://containous.github.io/traefik-helm-chart
+```
+
+You can update the chart repository by running:
+
+```bash
+helm repo update
 ```

 And install it with the `helm` command line:

 ```bash
-helm install ./traefik-helm-chart
+helm install traefik traefik/traefik
 ```

 !!! tip "Helm Features"
    
-    All [Helm features](https://v2.helm.sh/docs/using_helm/#using-helm) are supported.
+    All [Helm features](https://helm.sh/docs/intro/using_helm/) are supported.
    For instance, installing the chart in a dedicated namespace:

    ```bash tab="Install in a Dedicated Namespace"
+    kubectl create ns traefik-v2
    # Install in the namespace "traefik-v2"
    helm install --namespace=traefik-v2 \
-        ./traefik-helm-chart
+        traefik traefik/traefik
    ```

 ??? example "Installing with Custom Values"
    
    You can customize the installation by specifying custom values,
-    as with [any helm chart](https://v2.helm.sh/docs/using_helm/#customizing-the-chart-before-installing).
+    as with [any helm chart](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing).
    {: #helm-custom-values }
    
    The values are not (yet) documented, but are self-explanatory:
    you can look at the [default `values.yaml`](https://github.com/containous/traefik-helm-chart/blob/master/traefik/values.yaml) file to explore possibilities.
    
+    You can also set Traefik command line flags using `additionalArguments`.
    Example of installation with logging set to `DEBUG`:
    
    ```bash tab="Using Helm CLI"
    helm install --namespace=traefik-v2 \
-        --set="logs.loglevel=DEBUG" \
-        ./traefik-helm-chart
+        --set="additionalArguments={--log.level=DEBUG}" \
+        traefik traefik/traefik
    ```
    
    ```yml tab="With a custom values file"
    # File custom-values.yml
-    ## Install with "helm install --values=./custom-values.yml ./traefik-helm-chart
-    logs:
-        loglevel: DEBUG
+    ## Install with "helm install --values=./custom-values.yml traefik traefik/traefik
+    additionalArguments:
+      - "--log.level=DEBUG"
    ```
+    
+### Exposing the Traefik dashboard
+
+This HelmChart does not expose the Traefik dashboard by default, for security concerns.
+Thus, there are multiple ways to expose the dashboard.
+For instance, the dashboard access could be achieved through a port-forward :
+
+```shell
+kubectl port-forward $(kubectl get pods --selector "app.kubernetes.io/name=traefik" --output=name) 9000:9000
+```
+
+Accessible with the url: http://127.0.0.1:9000/dashboard/
+
+Another way would be to apply your own configuration, for instance,
+by defining and applying an IngressRoute CRD (`kubectl apply -f dashboard.yaml`):
+
+```yaml
+# dashboard.yaml
+apiVersion: traefik.containo.us/v1alpha1
+kind: IngressRoute
+metadata:
+  name: dashboard
+spec:
+  entryPoints:
+    - web
+  routes:
+    - match: Host(`traefik.localhost`) && (PathPrefix(`/dashboard`) || PathPrefix(`/api`))
+      kind: Rule
+      services:
+        - name: api@internal
+          kind: TraefikService
+```

+## Domain fronting
+
+Basically, [domain fronting](https://en.wikipedia.org/wiki/Domain_fronting) is a technique that allows to open a 
+connection with a specific domain name, thanks to the 
+[Server Name Indication](https://en.wikipedia.org/wiki/Server_Name_Indication), then access a service with another 
+domain set in the HTTP `Host` header.
+
+Since the `v2.2.2`, Traefik avoids (by default) using domain fronting.
+As it is valid for advanced use cases, the `HostHeader` and `HostSNI` [rules](../routing/routers/index.md#rule) allow 
+to fine tune the routing with the `Server Name Indication` and `Host header` value.
+
+If you encounter routing issues with a previously working configuration, please refer to the 
+[migration guide](../migration/v2.md) to update your configuration.

+
+### TLS
+
+#### Communication Between Traefik and Pods
+
+Traefik automatically requests endpoint information based on the service provided in the ingress spec.
+Although Traefik will connect directly to the endpoints (pods),
+it still checks the service port to see if TLS communication is required.
+
+There are 3 ways to configure Traefik to use https to communicate with pods:
+
+1. If the service port defined in the ingress spec is `443` (note that you can still use `targetPort` to use a different port on your pod).
+1. If the service port defined in the ingress spec has a name that starts with https (such as `https-api`, `https-web` or just `https`).
+1. If the ingress spec includes the annotation `traefik.ingress.kubernetes.io/service.serversscheme: https`.
+
+If either of those configuration options exist, then the backend communication protocol is assumed to be TLS,
+and will connect via TLS automatically.
+
+!!! info
+    
+    Please note that by enabling TLS communication between traefik and your pods,
+    you will have to have trusted certificates that have the proper trust chain and IP subject name.
+    If this is not an option, you may need to skip TLS certificate verification.
+    See the [insecureSkipVerify](../../routing/overview.md#insecureskipverify) setting for more details.
+
+#### Certificates Management
+
+??? example "Using a secret"
+    
+    ```yaml tab="Ingress"
+    kind: Ingress
+    apiVersion: networking.k8s.io/v1beta1
+    metadata:
+      name: foo
+      namespace: production
+    
+    spec:
+      rules:
+      - host: example.net
+        http:
+          paths:
+          - path: /bar
+            backend:
+              serviceName: service1
+              servicePort: 80
+    
+      tls:
+      - secretName: supersecret
+    ```
+      
+    ```yaml tab="Secret"
+    apiVersion: v1
+    kind: Secret
+    metadata:
+      name: supersecret
+    
+    data:
+      tls.crt: LS0tLS1CRUdJTiBDRVJUSUZJQ0FURS0tLS0tCi0tLS0tRU5EIENFUlRJRklDQVRFLS0tLS0=
+      tls.key: LS0tLS1CRUdJTiBQUklWQVRFIEtFWS0tLS0tCi0tLS0tRU5EIFBSSVZBVEUgS0VZLS0tLS0=
+    ```
+
+TLS certificates can be managed in Secrets objects.
+
+!!! info
+    
+    Only TLS certificates provided by users can be stored in Kubernetes Secrets.
+    [Let's Encrypt](../../https/acme.md) certificates cannot be managed in Kubernetes Secrets yet.
+
+## Global Default Backend Ingresses
+
+Ingresses can be created that look like the following:
+
+```yaml
+apiVersion: networking.k8s.io/v1beta1
+kind: Ingress
+metadata:
+ name: cheese
+
+spec:
+ backend:
+   serviceName: stilton
+   servicePort: 80
+```
+
+This ingress follows the Global Default Backend property of ingresses.
+This will allow users to create a "default router" that will match all unmatched requests.
+
+!!! info
+    
+    Due to Traefik's use of priorities, you may have to set this ingress priority lower than other ingresses in your environment,
+    to avoid this global ingress from satisfying requests that could match other ingresses.
+    
+    To do this, use the `traefik.ingress.kubernetes.io/router.priority` annotation (as seen in [Annotations on Ingress](#on-ingress)) on your ingresses accordingly.

+## Configuring UDP Routers
+
+!!! warning "The character `@` is not allowed in the router name"
+
+### General
+
+Similarly to TCP, as UDP is the transport layer, there is no concept of a request,
+so there is no notion of an URL path prefix to match an incoming UDP packet with.
+Furthermore, as there is no good TLS support at the moment for multiple hosts,
+there is no Host SNI notion to match against either.
+Therefore, there is no criterion that could be used as a rule to match incoming packets in order to route them.
+So UDP "routers" at this time are pretty much only load-balancers in one form or another.
+
+!!! important "Sessions and timeout"
+
+	Even though UDP is connectionless (and because of that),
+	the implementation of an UDP router in Traefik relies on what we (and a couple of other implementations) call a `session`.
+	It basically means that some state is kept about an ongoing communication between a client and a backend,
+	notably so that the proxy knows where to forward a response packet from a backend.
+	As expected, a `timeout` is associated to each of these sessions,
+	so that they get cleaned out if they go through a period of inactivity longer than a given duration (that is hardcoded to 3 seconds for now).
+	Making this timeout configurable will be considered later if we get more usage feedback on this matter.
+
+### EntryPoints
+
+If not specified, UDP routers will accept packets from all defined (UDP) entry points.
+If one wants to limit the router scope to a set of entry points, one should set the entry points option.

+## Configuring UDP Services
+
+### General
+
+Each of the fields of the service section represents a kind of service.
+Which means, that for each specified service, one of the fields, and only one,
+has to be enabled to define what kind of service is created.
+Currently, the two available kinds are `LoadBalancer`, and `Weighted`.
+
+### Servers Load Balancer
+
+The servers load balancer is in charge of balancing the requests between the servers of the same service.
+
+??? example "Declaring a Service with Two Servers -- Using the [File Provider](../../providers/file.md)"
+
+    ```toml tab="TOML"
+    ## Dynamic configuration
+    [udp.services]
+      [udp.services.my-service.loadBalancer]
+        [[udp.services.my-service.loadBalancer.servers]]
+          address = "xx.xx.xx.xx:xx"
+        [[udp.services.my-service.loadBalancer.servers]]
+          address = "xx.xx.xx.xx:xx"
+    ```
+
+    ```yaml tab="YAML"
+    ## Dynamic configuration
+    udp:
+      services:
+        my-service:
+          loadBalancer:
+            servers:
+            - address: "xx.xx.xx.xx:xx"
+            - address: "xx.xx.xx.xx:xx"
+    ```
+
+#### Servers
+
+The Servers field defines all the servers that are part of this load-balancing group,
+i.e. each address (IP:Port) on which an instance of the service's program is deployed.
+
+??? example "A Service with One Server -- Using the [File Provider](../../providers/file.md)"

+    ```
+
+### Weighted Round Robin
+
+The Weighted Round Robin (alias `WRR`) load-balancer of services is in charge of balancing the requests between multiple services based on provided weights.
+
+This strategy is only available to load balance between [services](./index.md) and not between [servers](./index.md#servers).
