Docker Registry 加速服务#

Warning

使用国内的 Docker Hub 镜像前，必须准备一个该镜像站对应的账号和密码，否则将无法通过该源加速。因此，使用无效源时，会被重定向到 https://registry-1.docker.io/v2/。

Error

科大 Docker Hub 不对校外开放，因此无法使用科大源。

sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd

删除无效的镜像#

# 清理 <none> 容器
docker image prune -f
docker rmi -f $(docker images | grep '<none>' | awk '{print $3}')

# 清理异常退出的容器
docker rm $(docker ps -a | grep Exited | awk '{print $1}')
