部署服务时，kubectl get all -o wide 查看到的pod异常运行状态

kubectl describe pod pod-hhja889hkjshaf87yh 最后看到异常信息 Error response from daemon: pull access denied for istio/citadel, repository does not exist or may require ‘docker login判断是未登录或无效造成的

docker login 后生成/root/.docker/config.json将文件复制到/var/lib/kubelet/config.json
