Docker镜像加速

docker 中，只能够为 docker 官方镜像仓库 hub.docker.com 提供 mirror 加速，自建的 docker 镜像仓库是不能配置 mirror 加速的

# Docker中国 mirror
https://registry.docker-cn.com
# 腾讯云 docker hub mirror
https://mirror.ccs.tencentyun.com
# 华为云镜像
https://05f073ad3c0010ea0f4bc00b7105ec20.mirror.swr.myhuaweicloud.com
# DaoCloud 镜像
http://f1361db2.m.daocloud.io
# 阿里云 docker hub mirror
https://registry.cn-hangzhou.aliyuncs.com

修改镜像仓库 mirror 地址

修改 /etc/docker/daemon.json 文件（如果没有，则创建）,添加 registry-mirrors 字段,重启 docker/kubelet

vim /etc/docker/daemon.json
{
 "registry-mirrors": ["https://registry.cn-hangzhou.aliyuncs.com"]
}

systemctl daemon-reload
systemctl restart docker
systemctl start kubelet # 假设您安装了 kubenetes
