【问题描述】：
我在 CentOS 7 上的 OpenVZ 容器上运行 docker，它已启动并正在运行，但我在尝试运行 docker run -it ubuntu bash 时遇到问题。
虽然docker run -it hello-world 和docker run -it busybox 成功。
我遇到以下问题：
[root@vps dir]# docker run -it ubuntu bash
Unable to find image 'ubuntu:latest' locally

docker.service 文件设置如下::

最后，这个问题被我的 VPS 提供商工作人员修复了，cmets 为
the issue originates with the amount of inodes allocated to the VPS, the VPS reinstall/build script allocated very few inodes vs what's really needed, I've corrected this now。我不确定在哪里添加此信息，因此添加了评论。
