Docker – 在拉取图片的同时超出磁盘配额
我在CentOS 7上运行OpenVZ容器上的docker，它运行正常，但是当我尝试运行docker run -it ubuntu bash 。
虽然docker run -it hello-world和docker run -it busybox成功。
我收到以下问题：
[root@vps dir]# docker run -it ubuntu bash Unable to find image 'ubuntu:latest' locally latest: Pulling from ubuntu 83e4dde6b9cf: Extracting [===================> ] 26.18 MB/65.79 MB 83e4dde6b9cf: Error downloading dependent layers 29460ac93442: Download complete d2a0ecffe6fa: Download complete d2a0ecffe6fa: Error pulling image (latest) from ubuntu, ApplyLayer exit status 1 stdout: stderr: open /usr/lib/perl/5.18.2/auto/PerlIO/scalar/scalar.bs: Error pulling image (latest) from ubuntu, ApplyLayer exit status 1 stdout: stderr: open /usr/lib/perl/5.18.2/auto/PerlIO/scalar/scalar.bs: disk quota exceeded
docker.service文件设置如下：
[Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network.target docker.socket Requires=docker.socket [Service] ExecStart=/usr/bin/docker -d -s vfs -H fd:// MountFlags=slave LimitNOFILE=1048576 LimitNPROC=1048576 LimitCORE=infinity [Install] WantedBy=multi-user.target
请指导我如何解决这个问题？
谢谢

也许你的磁盘空间（在这个OpenVZ容器中分配）已满？
如果是这种情况，请删除所有悬挂的图像：
alias drmiad='docker rmi $(docker images --filter "dangling=true" -q --no-trunc)' drmiad
