API

!!! important In the RC version, you can't configure middlewares (basic authentication or white listing) anymore, but as security is important, this will change before the GA version.

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).

!!! important In the beta version, you can't configure middlewares (basic authentication or white listing) anymore, but as security is important, this will change before the RC version.

Configuration

To enable the API handler:

[api]

api: {}

--api=true

dashboard

Optional, Default=true

Enable the dashboard. More about the dashboard features here.

[api]
  dashboard = true

api:
  dashboard: true

--api.dashboard=true

debug

Optional, Default=false

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

[api]
  debug = true

api:
  debug: true

--api.debug=true
