Kubernetes Java 客户端 API

Question

I am trying to authenticate to the kubernetes cluster while using kubernetes java client API. I am using config file from .kube/config and pasting it into my project directory structure. But the config file has expiry time, and it expires so my API fails, also sometimes when i generate the kubeconfig file it does not contain expiry time, thus the API fails. How to get the permanent credentials for kubernetes cluster and use it in my code?

Answer 1

Deploy the java application inside the kubernetes cluster as pod and use InClusterClientExample . In this case since the pod uses service account token it is guaranteed to work always because kubernetes takes care of refreshing the token.
