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.

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