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
