Nginx path is ignored? Bug or wrong configuration?

[goors]

I have Kubernetes with ingress config:

path: /nuget(/|$)(.*)

I thought that using PathBase as env variable with resolve issue, but it is not.

In this case I thought setting PathBase=/nuget with resolve this but when I got to mydomain.com/nuget/v3/index.json
In response JSON, I have mydomain.com/api/v2/package in instead of mydomain.com/nuget/api/v2/package.

What am I missing here?

I think you have a config like this

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-test
  annotations:
    nginx.ingress.kubernetes.io/use-regex: "true"
    nginx.ingress.kubernetes.io/rewrite-target: /$2
spec:
  rules:
   - host: test.domain.com
     http:
       paths:
       - path: /nuget(/|$)(.*)  # test.domain.com/nuget/api/v3 would redirect to the baget-service:80/api/v3
         pathType: Prefix
         backend:
           service:
             name: baget-service
             port:
               number: 80

you should change to something like this

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-test
  annotations:
    nginx.ingress.kubernetes.io/use-regex: "true"
    nginx.ingress.kubernetes.io/rewrite-target: /$1/$3
spec:
  rules:
   - host: test.domain.com
     http:
       paths:
       - path: /(nuget)(/|$)(.*)  # test.domain.com/nuget/api/v3 would redirect to the baget-service:80/nuget/api/v3
         pathType: Prefix
         backend:
           service:
             name: baget-service
             port:
               number: 80

This works for the requests coming from the external to the internal of the service, but not for the website. Like every websites hosted on in subpath, the html points to resources directly on / and doesn't work since this is another application.

Is using different subdomains the only solution?
