docker versionDocker CE 支持以下版本的 Ubuntu 操作系统：
-
Artful 17.10 (Docker CE 17.11 Edge +) -
Xenial 16.04 (LTS) -
Trusty 14.04 (LTS)
Docker CE 可以安装在 64 位的 x86平台或 ARM 平台上。Ubuntu 发行版中，LTS（Long-Term-Support）长期支持版本，会获得 5 年的升级维护支持，这样的版本会更稳定，因此在生产环境中推荐使用 LTS 版本,当前最新的 LTS 版本为 Ubuntu 16.04。
docker-engine，使用以下命令卸载旧版本：
讯享网sudo apt-get remove docker </span>docker-engine </span> docker.io
使用脚本自动安装
curl -fsSL get.docker.com -o get-docker.shsudo sh get-docker.sh –mirror AzureChinaCloud
讯享网sudo systemctl enable dockersudo systemctl start docker
- 先执行命令：apt-get autoremove docker-ce
- 删除 /etc/apt/sources.list.d 目录下的 docker.list 文件

-
it ：这是两个参数，一个是 -i ：交互式操作，一个是 -t 终端。我们这里打算进入 bash 执行一些命令并查看返回结果，因此我们需要交互式终端。 -
–rm ：这个参数是说容器退出后随之将其删除。默认情况下，为了排障需求，退出的容器并不会立即删除，除非手动 docker rm 。我们这里只是随便执行个命令，看看结果，不需要排障和保留结果，因此使用 –rm 可以避免浪费空间。 -
ubuntu:16.04 ：这是指用 ubuntu:16.04 镜像为基础来启动容器。 -
bash ：放在镜像名后的是命令，这里我们希望有个交互式 Shell，因此用的是 bash。
