docker 配置阿里云镜像

国外镜像经常卡

docker: error pulling image configuration: Get https://production.cloudflare.docker.com/registry-v2/docker/registry/v2/blobs/sha256/12/12d0d03473def9333e13e5f405cce2b1fa163cb9721255267e0cbe04a7a464eb/data?verify=1587049839-8XH2acmtoeht3%2BZf%2Fv%2FrCcihckE%3D: net/http: TLS handshake timeout.

touch /etc/docker/daemon.json
vim /etc/docker/daemon.json
{
  "registry-mirrors": ["https://tnxkcso1.mirror.aliyuncs.com"]
}

service docker restart

ok

OR

修改daemon配置文件/etc/docker/daemon.json来使用加速器
vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://f1z25q5p.mirror.aliyuncs.com"]
}
保存，运行下面命令，重启docker服务
sudo systemctl daemon-reload
sudo systemctl restart docker
