|
### 基本信息
|
|
[Ubuntu](https://en.wikipedia.org/wiki/Ubuntu) 是流行的 Linux 发行版，其自带软件版本往往较新一些。
|
|
|
|
该仓库位于 https://hub.docker.com/_/ubuntu/，提供了 Ubuntu 从 12.04 ~ 16.10 各个版本的镜像。
|
|
|
|
### 使用方法
|
|
默认会启动一个最小化的 Ubuntu 环境。
|
|
|
|
```
|
|
$ docker run --name some-ubuntu -i -t ubuntu
|
|
root@523c70904d54:/#
|
|
```
|
|
|
|
