目前这几个image pull policy都是Always，直接执行下面的命令
kubectl rollout restart deployments ks-installer -n kubesphere-system
kubectl rollout restart deployments ks-apiserver -n kubesphere-system
kubectl rollout restart deployments ks-controller-manager -n kubesphere-system
kubectl rollout restart deployments ks-console -n kubesphere-system
