Override the default Traefik configuration values (see yaml file or CLI).
Append your own configurations (for example, by running kubectl apply -f myconf.yaml).

Examples of common usage are provided.

If you need to include additional Kubernetes objects or extend functionality, use extraObjects or add this chart as a subchart.

Major Changes

Starting with v28.x, this chart bootstraps Traefik Proxy version 3 as a Kubernetes ingress controller, using the IngressRoute Custom Resource.

To upgrade from chart versions prior to v28.x (which use Traefik Proxy version 2), see:

Migration guide from v2 to v3
Upgrade notes in the README on the v27 branch

Starting with v34.x, to work around Helm caveats, you can use an additional chart dedicated to CRDs: traefik-crds.

⚠️ This has been deprecated since v38.0.2.

Support for Traefik Proxy v2

If you need to use this chart with Traefik Proxy v2, use chart version v27.x.

This chart's support policy aligns with the upstream support policy of Traefik Proxy.

For compatibility details, installation instructions, or previous upgrade notes, check the README on the v27 branch.

Installing

Prerequisites

Kubernetes (server) version v1.22.0 or higher: kubectl version
Helm v3.9.0 or higher installed: helm version
Traefik's chart repository: helm repo add traefik https://traefik.github.io/charts

Deploying

Standard Installation

To install the chart with default values:

helm install traefik traefik/traefik

or, to install from the OCI registry:

helm install traefik oci://ghcr.io/traefik/helm/traefik

To customize the installation, provide a custom values file:

helm install -f myvalues.yaml traefik traefik/traefik

To see example values files, refer to the provided EXAMPLES.

For complete documentation on all available parameters, check the default values file.

With Additional CRDs Chart (⚠️ deprecated)

Caution

The traefik-crds chart is deprecated. It will be removed soon

To manage CRDs separately, use the optional CRDs chart. When using it, the CRDs from the regular Traefik chart are not required. For more details, see here.

To install with the CRDs chart:

helm install traefik-crds traefik/traefik-crds
helm install traefik traefik/traefik --skip-crds
helm list # should display two charts installed

Verification

Starting with v37.0.0, chart releases are signed using provenance files.

To verify the chart, follow these steps:

1. Download the Public Signing Key

To download the official Traefik Helm chart signing key, run:

gpg --receive-keys --keyserver hkps://keys.openpgp.org 'B0FBA7678F685E9B7024B79FFD92BB57C5A71A99'

Example output:

gpg: key FD92BB57C5A71A99: public key "TraefikLabs Chart Signing Key <noreply@traefik.io>" imported
gpg: Total number processed: 1
gpg:               imported: 1

2. Export the Signing Key

By default, GnuPG v2 stores keyrings in a format that is not compatible with Helm chart provenance verification. Before you can verify a Helm chart, you must convert your keyrings to the legacy format:

gpg --export --output $HOME/.gnupg/pubring.gpg 'B0FBA7678F685E9B7024B79FFD92BB57C5A71A99'

3. Verify the Chart

To verify the chart, use the appropriate command for your registry:

OCI Registry

helm fetch --verify --keyring $HOME/.gnupg/traefik.pubring.gpg oci://ghcr.io/traefik/helm/traefik:<VERSION>

Helm Registry (GitHub Pages)

helm fetch --verify --keyring $HOME/.gnupg/traefik.pubring.gpg traefik/traefik --version <VERSION>

Upgrading

To see what has changed in each release, check the Changelog.

A new major version indicates that there is an incompatible breaking change.

Warning

To avoid issues, always read the release notes for this chart before upgrading.

Upgrade the Standalone Traefik Chart

If you use Helm's native CRD management, you MUST upgrade CRDs before running helm upgrade, since Helm does not update CRDs automatically. See HIP-0011 for details.

To upgrade the Traefik chart and its CRDs:

# Update the chart repository
helm repo update
# Check current chart & Traefik version
helm search repo traefik/traefik
# Update CRDs
helm show crds traefik/traefik | kubectl apply --server-side --force-conflicts -f -
# Upgrade Traefik release
helm upgrade traefik traefik/traefik

Upgrade from the Standard Traefik Chart to Traefik + Opt-In CRDs Chart

Caution

The traefik-crds chart is deprecated. It will be removed soon

Warning

To avoid conflicts, you must change the ownership of CRDs before installing the CRDs chart.

To migrate to the setup with the additional CRDs chart:

# Update the chart repository
helm repo update
# Update CRD ownership
kubectl get customresourcedefinitions.apiextensions.k8s.io -o name | grep traefik.io | \
  xargs kubectl patch --type='json' -p='[{"op": "add", "path": "/metadata/labels", "value": {"app.kubernetes.io/managed-by":"Helm"}},{"op": "add", "path": "/metadata/annotations/meta.helm.sh~1release-name", "value":"traefik-crds"},{"op": "add", "path": "/metadata/annotations/meta.helm.sh~1release-namespace", "value":"default"}]'
# If you use gateway API, also change Gateway API ownership
kubectl get customresourcedefinitions.apiextensions.k8s.io -o name | grep gateway.networking.k8s.io | \
  xargs kubectl patch --type='json' -p='[{"op": "add", "path": "/metadata/labels", "value": {"app.kubernetes.io/managed-by":"Helm"}},{"op": "add", "path": "/metadata/annotations/meta.helm.sh~1release-name", "value":"traefik-crds"},{"op": "add", "path": "/metadata/annotations/meta.helm.sh~1release-namespace", "value":"default"}]'
# Deploy the optional CRDs chart
helm install traefik-crds traefik/traefik-crds
# Upgrade Traefik release
helm upgrade traefik traefik/traefik

Upgrade When Using Both Traefik and Opt-In CRDs Chart

Caution

The traefik-crds chart is deprecated. It will be removed soon

To upgrade both Traefik and CRDs charts:

# Update the chart repository
helm repo update
# Check the current chart & Traefik version
helm search repo traefik/traefik
# Upgrade CRDs (Traefik Proxy v3 CRDs)
helm upgrade traefik-crds traefik/traefik
# Upgrade Traefik release
helm upgrade traefik traefik/traefik
