k8s 拉取私有仓库失败

k8s 报错拉取镜像失败 Error response from daemon: pull access denied for istio/citadel, repository does not exist or may require ‘docker login’   docker login后,把配置拷贝到以下目录的其中一个。如果是${HOME}/.docker/config.json看说明是要额外设环境变量给kubelet的,可以试试放在/var/lib/kubelet/config.json   Docker stores keys for private registries in the $HOME/.dockercfg or $HOME/.docker/config.json file. If you put the same file in the search paths list below, kubelet uses it as the credential provider when pulling images.

{cwd of kubelet}/config.json
{cwd of kubelet}/.dockercfg
Note: You may have to set HOME=/root explicitly in your environment file for kubelet.
