Where can I see list of services registered in Kubernetes Discovery?


In case of using eureka (+ Spring Boot) you can reach special endpoint where list of currently registered instances can be found. E.g.: Instances currently registered with Eureka

Does Kubernetes service discovery have such endpoint or may be other mechanism to see all currently registered instances? UPD: Does kubernetes api have any possibilities to do this, may be via kubectl?


Solution

  • I managed to solve problem after a while.

    1. Add endpoint in of your microservices. Example here
    2. Add roles to your kubernetes cluster:
    kind: ClusterRole
    apiVersion: rbac.authorization.k8s.io/v1
    metadata:
      namespace: yours
      name: service-reader
    rules:
      - apiGroups: [""] # "" indicates the core API group
        resources: ["services"]
        verbs: ["get", "watch", "list"]
    
    apiVersion: rbac.authorization.k8s.io/v1
    kind: ClusterRoleBinding
    metadata:
      name: service-reader-pod
    subjects:
      - kind: ServiceAccount
        name: default
        namespace: yours
    roleRef:
      kind: ClusterRole
      name: service-reader
      apiGroup: rbac.authorization.k8s.io
