Docker 配置镜像加速

docker 拉取代码时出现

ERROR: failed to solve: node:16: unexpected status from HEAD request to https:// xxxxxx.mirror.aliyuncs.com/v2/library/node/manifests/16?ns=docker.io: 403 Forb idden

ERROR: failed to solve: node:16: failed to do request: Head "https://mirror.ccs. tencentyun.com/v2/library/node/manifests/16?ns=docker.io": dial tcp: lookup mirr or.ccs.tencentyun.com on 10.200.200.70:53: no such host

Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: re quest canceled while waiting for connection (Client.Timeout exceeded while await

类似以上错误

需要配置镜像加速

vim /etc/docker/daemon.json

然后添加以下内容

{

"registry-mirrors": [ "https://docker.m.daocloud.io" ]

}

保存并退出，重新启动一下docker

systemctl restart docker

我这里使用的是Daocloud 镜像加速器地址：https://docker.m.daocloud.io

你也可以尝试使用其他镜像加速地址，但是各大高校以及容器技术社区，由于众所周不知的原因， 纷纷关闭多个镜像加速站点。
