在我的例子中，我运行了docker系统df来找出哪个组件占用了更多的空间，然后我执行了docker系统prune -a来清理所有悬挂的容器、图像等。最后，我运行docker卷rm $(docker卷ls -qf悬挂=true)来清理悬挂卷。

下面是按顺序执行的命令。

docker system df
docker system prune -a
docker volume rm $(docker volume ls -qf dangling=true)

如果你使用Docker桌面，你可以通过Docker的首选项在高级设置中增加磁盘镜像大小。

以下是macOS的截图:

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

如果它只是Docker的测试安装(即不是生产)，并且你不关心做核清洁，你可以:

清洁所有容器: docker ps -a | sed '1 d' | awk '{print $1}' | xargs -L1 docker rm

清除所有图像: docker images -a | sed '1 d' | awk '{print $3}' | xargs -L1 docker rmi -f

同样，我在开发Docker的ec2实例中使用了这个方法，而不是在任何严肃的QA或生产路径中使用。伟大的事情是，如果你有你的Dockerfile(s)，它很容易重建或docker拉。

我刚碰到这个。我用的是Ubuntu 20.04。工作什么?重新安装码头工人:

sudo apt-get purge docker-ce docker-ce-cli containerd.io
sudo apt-get install docker-ce docker-ce-cli containerd.io

有点粗鲁，我知道。我试着修剪Docker，但还是不管用。

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?)
