Question

我在CentOS 7上的OpenVZ容器上运行docker，它启动并运行但我在尝试运行docker run -it ubuntu bash时出现问题。

虽然docker run -it hello-world和docker run -it busybox成功了。

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

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

请指导我如何解决此问题？

Answer 1

也许您的磁盘空间（在此OpenVZ容器中分配）已满？

如果是这种情况，请删除所有悬空图像：

alias drmiad='docker rmi $(docker images --filter "dangling=true" -q --no-trunc)'
drmiad

Docker - 在拉动图像时超出磁盘配额
