Use k8s

When the service is deployed, the pod running status displayed by kubectl get all -o wide is abnormal

kubectl describe pod pod-hhja889hkjshaf87yh see the last exception information Error response from daemon: pull access denied for istio/citadel, repository does not exist or may require 'docker login', it is judged that it is caused by no login or the login has not taken effect

Requires login on all nodes

Generate /root/.docker/config.json file after docker login, copy the file to /var/lib/kubelet/config.json

Then redeploy to pull the image normally
