I'm currently using traefik 1.6.x as ingress controller in my K8s clusters. I wanted to update to 1.7.x (and then to 2.x later on), but my ingresses are not working anymore after the update.

The issue seems to be, that I do http method restrictions on my ingresses by adding the methods to the traefik.frontend.rule.type annotation as follows:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: app-name
  namespace: namespace1
  annotations:
    kubernetes.io/ingress.class: traefik
    traefik.frontend.rule.type: "Method: CONNECT, DELETE, GET, HEAD, OPTIONS, PATCH, POST, PUT; PathPrefix"
    ingress.kubernetes.io/hsts-max-age: "315360000"
    ingress.kubernetes.io/hsts-include-subdomains: "true"
    ingress.kubernetes.io/custom-frame-options-value: "SAMEORIGIN"
    ingress.kubernetes.io/content-type-nosniff: "true"
    ingress.kubernetes.io/browser-xss-filter: "true"
    ingress.kubernetes.io/custom-response-headers: "Server:||X-Application-Context:||X-Powered-By:||exception:"
spec:
  rules:
    - host: ...

I don't know if this was ever intended to be done in this way, but apparently it worked. I found that in some other StackOverflow post, iirc.

Removing the Method part (or the whole annotation then, because PathPrefix is the default) brings the routes back to life. But of course this allows the TRACE method again, for example.

Is there another way to restrict those (maybe even for all ingresses) with traefik versions from 1.7.x?

Thanks in advance!
