Docker版本说明
参考官网： https://docs.docker.com/release-notes/docker-engine/
主要意思是 Docker Engine 的版本号范围: 0.1.0 ~ 1.13.1。 新的版本变更为 Docker CE or Docker EE.
在 2017 年 3 月 2 日, docker 团队宣布
- 企业版 Docker Enterprise Edition ( EE ) 发布.
- 免费的 Docker Engine 改名为 Docker Community Edition ( CE )
并且采用基于时间的版本号方案.
Docker EE 和 Docker CE 第一个采用新的版本号方案的版本为17.03 。
Docker CE 的两个版本
- Stable 每个季度提供可靠更新
- Edge 每个月提供新功能
Docker安装
官方指导文档： https://docs.docker.com/install/linux/docker-ce/centos/
我这里要是装的是 17.12的版本

# 设置stable 的仓库

Step2. Enable the nightly or test repositories（Optional）
可以选择是否开启edge和test仓库,这里调过操作
Step3. INSTALL DOCKER CE
这里我们选择第二种方式，来安装特定版本的docker ce

运行hello-world镜像来测试是否安装成功,本地没有镜像时会自动从docker hub中下载,当出现Hello from Docker!即表示安装成功

Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
