Install Traefik

You can install Traefik with the following flavors:

Use the Official Docker Image

Choose one of the official Docker images and run it with one sample configuration file:

  1. docker run -d -p 8080:8080 -p 80:80 \
  2.     -v $PWD/traefik.yml:/etc/traefik/traefik.yml traefik:v2.11

For more details, go to the Docker provider documentation

Tip

  • Prefer a fixed version than the latest that could be an unexpected version. ex: traefik:v2.11
  • Docker images are based from the Alpine Linux Official image.
  • Any orchestrator using docker images can fetch the official Traefik docker image.

Use the Helm Chart

Warning

The Traefik Chart from Helm’s default charts repository is still using Traefik v1.7.

Traefik can be installed in Kubernetes using the Helm chart from https://github.com/traefik/traefik-helm-chart.

Ensure that the following requirements are met:

  • Kubernetes 1.16+
  • Helm version 3.9+ is installed

Add Traefik Labs chart repository to Helm:

  1. helm repo add traefik https://traefik.github.io/charts

You can update the chart repository by running:

  1. helm repo update

And install it with the Helm command line:

  1. helm install traefik traefik/traefik

Helm Features

All Helm features are supported.

Examples are provided here.

For instance, installing the chart in a dedicated namespace:

Install in a Dedicated Namespace

  1. kubectl create ns traefik-v2
  2. # Install in the namespace "traefik-v2"
  3. helm install --namespace=traefik-v2 \
  4.     traefik traefik/traefik

Installing with Custom Values

You can customize the installation by specifying custom values, as with any helm chart.

All parameters are documented in the default values.yaml.

You can also set Traefik command line flags using additionalArguments. Example of installation with logging set to DEBUG:

Using Helm CLI

  1. helm install --namespace=traefik-v2 \
  2.     --set="additionalArguments={--log.level=DEBUG}" \
  3.     traefik traefik/traefik

With a custom values file

  1. # File custom-values.yml
  2. ## Install with "helm install --values=./custom-values.yml traefik traefik/traefik
  3. additionalArguments:
  4.   - "--log.level=DEBUG"

Exposing the Traefik dashboard

This Helm chart 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:

  1. kubectl port-forward $(kubectl get pods --selector "app.kubernetes.io/name=traefik" --output=name) 9000:9000

It can then be reached at: 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):

  1. # dashboard.yaml
  2. apiVersion: traefik.io/v1alpha1
  3. kind: IngressRoute
  4. metadata:
  5.   name: dashboard
  6. spec:
  7.   entryPoints:
  8.     - web
  9.   routes:
  10.     - match: Host(`traefik.localhost`) && (PathPrefix(`/dashboard`) || PathPrefix(`/api`))
  11.       kind: Rule
  12.       services:
  13.         - name: api@internal
  14.           kind: TraefikService
