6.8. Using wildcard routes

The HAProxy Ingress Controller has support for wildcard routes. The Ingress Operator uses wildcardPolicy to configure the ROUTER_ALLOW_WILDCARD_ROUTES environment variable of the Ingress Controller.

The default behavior of the Ingress Controller is to admit routes with a wildcard policy of None, which is backwards compatible with existing IngressController resources.

Procedure

  1. Configure the wildcard policy.

    1. Use the following command to edit the IngressController resource: 

      $ oc edit IngressController

    2. Under spec, set the wildcardPolicy field to WildcardsDisallowed or WildcardsAllowed: 

      spec:
  routeAdmission:
    wildcardPolicy: WildcardsDisallowed # or WildcardsAllowed
