Web / Traefik Interview questions

How do you enable the Traefik dashboard?

The dashboard is enabled in the static configuration by setting api.dashboard: true, then exposing it through a router just like any other service, since the dashboard itself is served as an internal Traefik service named api@internal.

In production it should never be exposed without protection; a common pattern is to attach a BasicAuth or ForwardAuth middleware to the dashboard router, or restrict it to an internal-only entrypoint.

api:
  dashboard: true

# dynamic config
http:
  routers:
    dashboard:
      rule: "Host(`traefik.example.com`)"
      service: api@internal
      middlewares:
        - dashboard-auth
