## Docker
2+
3+
基础概念
4+
5+
- Images（镜像）：Docker可以通过Pull和Push命令构建对象到服务中心
6+
- Containers（容器）：Docker可以通过Start/Stop命令管理容器的生命周期
7+
- Logging（日志）：Docker可以通过stdout，stderro捕获输出所有的容器内部信息
8+
- Volumes（存储）：Docker可以创建和管理容器的相关文件存储
9+
- Networking（网络）：Docker可以创建管理虚拟的接口和内部所有容器之间的网络桥接
10+
- RPC：Docker服务器提供允许外部程序去控制所有容器的行为的API
11+
12+
13+
配置加速器
14+
15+
注册：[配置 Docker 加速器](https://www.daocloud.io/mirror#accelerator-doc)
16+
17+
配置：
18+
```
19+
$ curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sudo sh -s http://12248bc3.m.daocloud.io
20+
```
21+
22+
23+
安装
24+
25+
参考：https://docs.docker.com/engine/installation/
26+
27+
```
28+
$ curl -sSL https://get.daocloud.io/docker | sh
29+
```
30+
31+
```
32+
If you would like to use Docker as a non-root user, you should now consider
33+
adding your user to the "docker" group with something like:
34+
35+
sudo usermod -aG docker zhanghe
36+
37+
Remember that you will have to log out and back in for this to take effect!
38+
```
39+
40+
41+
检查 docker 守护进程状态
42+
```
43+
$ sudo service docker status
44+
```
45+
46+
```
47+
docker start/running, process 1650
48+
```
49+
50+
51+
获取当前 docker 版本
52+
```
53+
$ sudo docker version
