API

Traefik exposes a number of information through an API handler, such as the configuration of all routers, services, middlewares, etc.

As with all features of Traefik, this handler can be enabled with the static configuration.

Security

Enabling the API in production is not recommended, because it will expose all configuration elements, including sensitive data.

In production, it should be at least secured by authentication and authorizations.

A good sane default (non exhaustive) set of recommendations would be to apply the following protection mechanisms:

• At the transport level: NOT publicly exposing the API's port, keeping it restricted to internal networks (as in the principle of least privilege, applied to networks).

Configuration

If you enable the API, a new special service named api@internal is created and can then be referenced in a router.

To enable the API handler, use the following option on the static configuration:

# Static Configuration
[api]

# Static Configuration
api: {}

--api=true

And then define a routing configuration on Traefik itself with the dynamic configuration:

--8<-- "content/operations/include-api-examples.md"

??? warning "The router's rule must catch requests for the URI path /api" Using an "Host" rule is recommended, by catching all the incoming traffic on this host domain to the API. However, you can also use "path prefix" rule or any combination or rules.

```bash tab="Host Rule"
# Matches http://traefik.example.com, http://traefik.example.com/api
# or http://traefik.example.com/hello
rule = "Host(`traefik.example.com`)"
```

```bash tab="Path Prefix Rule"
# Matches http://api.traefik.example.com/api or http://example.com/api
# but does not match http://api.traefik.example.com/hello
rule = "PathPrefix(`/api`)"
```

```bash tab="Combination of Rules"
# Matches http://traefik.example.com/api or http://traefik.example.com/dashboard
# but does not match http://traefik.example.com/hello
rule = "Host(`traefik.example.com`) && (PathPrefix(`/api`) || PathPrefix(`/dashboard`))"
```

insecure

Enable the API in insecure mode, which means that the API will be available directly on the entryPoint named traefik.

!!! info If the entryPoint named traefik is not configured, it will be automatically created on port 8080.

[api]
  insecure = true

api:
  insecure: true

--api.insecure=true

dashboard

Optional, Default=true

Enable the dashboard. More about the dashboard features here.

[api]
  dashboard = true

api:
  dashboard: true

--api.dashboard=true

!!! warning "With Dashboard enabled, the router rule must catch requests for both /api and /dashboard" Please check the Dashboard documentation to learn more about this and to get examples.

debug

Optional, Default=false

Enable additional endpoints for debugging and profiling, served under /debug/.

[api]
  debug = true

api:
  debug: true

--api.debug=true
