docker 中，只能夠為 docker 官方鏡像倉庫 hub.docker.com 提供 mirror 加速，自建的 docker 鏡像倉庫是不能配置 mirror 加速的
# Docker中國 mirror
https://registry.docker-cn.com
# 騰訊雲 docker hub mirror
https://mirror.ccs.tencentyun.com
# 華為雲鏡像
https://05f073ad3c0010ea0f4bc00b7105ec20.mirror.swr.myhuaweicloud.com
# DaoCloud 鏡像
http://f1361db2.m.daocloud.io
# 阿里雲 docker hub mirror
https://registry.cn-hangzhou.aliyuncs.com
修改鏡像倉庫 mirror 地址
修改 /etc/docker/daemon.json 文件（如果沒有，則創建）,添加 registry-mirrors 字段,重啟 docker/kubelet
vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://registry.cn-hangzhou.aliyuncs.com"]
}
systemctl daemon-reload
systemctl restart docker
systemctl start kubelet # 假設您安裝了 kubenetes
查看修改結果
