Configure Argo CD Config

For Argo CD with HTTPS enabled, adding clusters becomes cumbersome—it requires logging into the server pod for configuration. Follow these steps:

# cat ~/.argocd/config
contexts:
- name: argocd-server.argocd
  server: qacd.test.cn
  user: argocd-server.argocd
current-context: argocd-server.argocd
servers:
- grpc-web-root-path: ""
  insecure: true
  server: qacd.test.cn
users:
- auth-token: xxxxxx # This is the token generated in step 1
  name: argocd-server.argocd

Configure kubeconfig

Skip detailed configuration here—refer to previous documentation. Ensure you can access the cluster and have cluster administrator privileges. Set the CONTEXT to idc-bj-k8s.
