我在RHEL机器上也遇到了这个问题。在堆栈溢出和docker-hub社区中，我没有找到任何合适的解决方案。 如果您在执行以下命令后仍面临此问题:

Docker系统全部修剪

最终奏效的解决方案:

docker info To check current docker storage driver Mine was : Storage Driver: devicemapper; If you have storage driver as overlay2 nothing to worry about. Solution will still work for you. df -h This is to check the available file systems on machine and the path where they are mounted. Two mounted path to have a note: /dev/mapper/rootvg-var 7.6G 1.2G 6.1G 16% /var /dev/mapper/rootvg-apps 60G 9.2G 48G 17% /apps Note- By default docker storage path is /var/lib/docker. It has available space ~6 GB and hence all the space related issues. So basically, I have to move default storage to some other storage where available space is more. For me its File sysyem path '/dev/mapper/rootvg-apps' which is mounted on /apps. Now task is to move /var/lib/docker to something like /apps/newdocker/docker. mkdir /apps/newdocker/docker chmod -R 777 /apps/newdocker/docker Update docker.serive file on linux which resides under: /usr/lib/systemd/system vi /usr/lib/systemd/system/docker.service if storage device is devicemapper , comment existing ExecStart line and add below under [Service]: ExecStart= ExecStart=/usr/bin/dockerd -s devicemapper --storage-opt dm.fs=xfs --storage-opt dm.basesize=40GB -g /apps/newdocker/docker --exec-opt native.cgroupdriver=cgroupfs Or if storage device is overlay2: just add -g /apps/newdocker/docker in the existing ExexStart statement. Something like ExecStart=/usr/bin/dockerd -g /apps/newdocker/docker -H fd:// --containerd=/run/containerd/containerd.sock rm -rf /var/lib/docker (It will delete all existing docker data) systemctl stop docker ps aux | grep -i docker | grep -v grep If no output has been produced by the above command, reload systemd daemon by below command. systemctl daemon-reload systemctl start docker docker info Check out the Data Space Available: 62.15GB after mouting to docker to new File system. DONE

这可能是因为默认存储空间设置为40GB(默认路径，/var/lib/docker)

您可以更改存储卷指向不同的路径

编辑文件-> /etc/sysconfig/docker-storage 在行下更新(如果不存在则添加)

DOCKER_STORAGE_OPTIONS = '——存储驱动=叠加图= CUSTOM_PATH '

重启码头工人 Systemctl stop docker systemctl daemon-reload Systemctl start docker

如果你运行命令docker info(它应该显示存储驱动为overlay)

立即删除所有未使用的容器、卷、网络和映像(https://docs.docker.com/engine/reference/commandline/system_prune/):

docker system prune -a -f --volumes

如果还不够，可以先删除正在运行的容器:

docker rm -f $(docker ps -a -q)
docker system prune -a -f --volumes

增加/var/lib/docker或使用其他空间更大的位置也是消除此错误的好选择(参见如何更改docker镜像安装目录?)

使用以下命令清洁Docker:

docker images --no-trunc | awk '/<none>/ { print $3 }' \
| xargs docker rmi

我在GCP mashine上遇到了这个问题。没有一种修剪方法对我有效。/var/lib/docker仍然重约160gb。然后我停了下来 服务docker停止删除docker缓存文件夹。

Sudo rm -rf /var/lib/docker。重新启动docker服务后，这个删除的文件夹被重新创建为明确的docker系统文件夹。当然，我丢失了所有的docker数据，但释放了磁盘空间。

在我的例子中，发生这种情况是因为我超过了Docker映像大小的10Gb限制。这似乎已经有所缓解，有一种方法可以将限制增加到100Gb (https://github.com/moby/moby/issues/5151)，但我不确定如何—对于我的用例，切换到映射卷是可以的，无论如何都有更好的性能。
