docker system df

可知，Docker 镜像占用了7.6GB磁盘，Docker 容器占用了3.18MB磁盘，Docker 数据卷占用了0磁盘

docker 空间清理

docker system prune命令可以用于清理磁盘，删除关闭的容器、无用的数据卷和网络，以及 dangling 镜像(即无 tag 的镜像)。docker system prune -a命令清理得更加彻底，可以将没有容器使用 Docker 镜像都删掉。注意，这两个命令会把你暂时关闭的容器，以及暂时没有用到的 Docker 镜像都删掉

WARNING! This will remove:

  • all stopped containers
  • all networks not used by at least one container
  • all images without at least one container associated to them
  • all build cache
