镜像加速说明

建议自建使用，底部按钮获取代码

为了加速镜像拉取，使用以下命令设置registry mirror：


sudo tee /etc/docker/daemon.json <<EOF
{
    "registry-mirrors": ["https://${workers_host}"]
}
EOF


sudo systemctl daemon-reload


sudo systemctl restart docker

用法：

原拉取镜像命令：


docker pull library/alpine:latest

加速拉取镜像命令：


docker pull ${workers_host}/library/alpine:latest

觉得不错点此赞赏
