Hello, I have created several middleware-definitions within the traefik-namespace and I am using them in several other projects and namespaces with traefik 2.4.9
The ingressroute definitions actually look like this:
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
name: app-public-http
namespace: registry
spec:
entryPoints:
- public-http
routes:
- kind: Rule
match: Host(`docker.xxxx.com`)
middlewares:
- name: redirect-to-https-temp
namespace: traefik-2
services:
- name: registry
port: 5000
The middlewares in the namespace traefik-2 look like this:
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
name: redirect-to-https-temp
namespace: traefik-2
resourceVersion: "1151"
uid: 22a57a07-9ca0-497a-85a5-44716a64a0e4
spec:
redirectScheme:
scheme: https
When upgrading to traefik 2.5.1 or 2.5.2, this is not working anymore and I get many of the following errors:
time="2021-09-13T16:23:16Z" level=error msg="Failed to create middleware keys: middleware traefik-2/redirect-to-https-temp is not in the IngressRoute namespace registry" ingress=app-public-http namespace=registry providerName=kubernetescrd
The service endpoints using those middlewares are not available.
I have searched around for a solution and I am wondering about if this is related to Avoid unauthorized middleware cross namespace reference by jbdoumenjou · Pull Request #8322 · traefik/traefik · GitHub
Can somebody tell me how to fix this?
The traefik Dashboard does not tell anything about these errors. However, the number of the Routers is greatly reduced:
traefik 2.4.9
traefik 2.5.1
Thanks and kind regards!
