The chain middleware enables you to define reusable combinations of other pieces of middleware. It makes it effortless to reuse the same groups.

Example

Below is an example of a chain containing AllowList, BasicAuth, and RedirectScheme.

apiVersion: traefik.io/v1alpha1
kind: IngressRoute
metadata:
  name: test
  namespace: default
spec:
  entryPoints:
    - web
  routes:
    - match: Host(`mydomain`)
      kind: Rule
      services:
        - name: whoami
          port: 80
      middlewares:
        - name: secured
