Boot Environment

Traefik Proxy’s configuration is divided into two main categories:

• Install Configuration: (formerly known as the static configuration) Defines parameters that require Traefik to restart when changed. This includes entry points, providers, API/dashboard settings, and logging levels.
• Routing Configuration: (formerly known as the dynamic configuration) Involves elements that can be updated without restarting Traefik, such as routers, services, and middlewares.

This section focuses on setting up the install configuration, which is essential for Traefik’s initial boot.

Configuration Methods

Traefik offers multiple methods to define install configuration.

!!! warning "Note" It’s crucial to choose one method and stick to it, as mixing different configuration options is not supported and can lead to unexpected behavior.

Here are the methods available for configuring the Traefik proxy:

• File
• CLI
• Environment Variables
• Helm

File

You can define the install configuration in a file using formats like YAML or TOML.

Configuration Example

entryPoints:
  web:
    address: ":80"
  websecure:
    address: ":443"

providers:
  docker: {}

api:
  dashboard: true

log:
  level: INFO

[entryPoints]
  [entryPoints.web]
    address = ":80"

  [entryPoints.websecure]
    address = ":443"

[providers]
  [providers.docker]

[api]
  dashboard = true

[log]
  level = "INFO"

Configuration File

At startup, Traefik searches for install configuration in a file named traefik.yml (or traefik.yaml or traefik.toml) in the following directories:

• /etc/traefik/
• $XDG_CONFIG_HOME/
• $HOME/.config/
• . (the current working directory).

You can override this behavior using the configFile argument like this:

traefik --configFile=foo/bar/myconfigfile.yml

CLI

Using the CLI, you can pass install configuration directly as command-line arguments when starting Traefik.

Configuration Example

traefik \
  --entryPoints.web.address=":80" \
  --entryPoints.websecure.address=":443" \
  --providers.docker \
  --api.dashboard \
  --log.level=INFO

Environment Variables

You can also set the install configuration using environment variables. Each option corresponds to an environment variable prefixed with TRAEFIK_.

Configuration Example

TRAEFIK_ENTRYPOINTS_WEB_ADDRESS=":80" TRAEFIK_ENTRYPOINTS_WEBSECURE_ADDRESS=":443" TRAEFIK_PROVIDERS_DOCKER=true TRAEFIK_API_DASHBOARD=true TRAEFIK_LOG_LEVEL="INFO" traefik

Helm

When deploying Traefik Proxy using Helm in a Kubernetes cluster, the install configuration is defined in a values.yaml file.

You can find the official Traefik Helm chart on GitHub

Configuration Example

ports:
  web:
    exposedPort: 80
  websecure:
    exposedPort: 443

additionalArguments:
  - "--providers.kubernetescrd.ingressClass"
  - "--log.level=INFO"
