路径通配符在 kubernetes 入口中不起作用

Question

I have installed Ingress and linked my service to it (usign metallb).

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: test-ingress
  annotations:
     nginx.ingress.kubernetes.io/rewrite-target: /
spec:
   rules:
   - http:
       paths:
       - path: /api/tasks/*
         # pathType: Exact
         backend:
           serviceName: tasks-service
           servicePort: 5004

The thing is this, I set up the default prefix of the paths in the deployment to be

/api/tasks/

where /api/tasks/tasks shows the service is up while /api/tasks/tasks_count gives the total number. However in my k8s cluster, I cannot redirect to the different paths within the service. What could be the problem?

Since this is a result in Google for wildcards and prefixes, I'll answer this old question.

The functionality you're looking for comes from specifying the path type as pathType: Prefix

       paths:
       - path: /api/tasks
         pathType: Prefix
         backend:
           serviceName: tasks-service
           servicePort: 5004

Importantly, the path doesn't contain a wildcard character. In fact, cloud providers like AWS will throw errors if you're using their custom load balancer provisioners for Ingress resources:

prefix path shouldn't contain wildcards
