docker的基本使用
安装docker
如果你配置了Homebrew工具的话，使用brew cask install docker就可以快速安装docker桌面工具。
或者从docker官网https://www.docker.com/products/docker-desktop下载安装包安装。

Version: 0.18.0
GitCommit: fec3683配置docker国内镜像
从docker官网上面下载镜像时，由于网络原因，下载速度非常慢，还有可能下载失败，因此安装完docker后就应马上配置docker的国内镜像站。
可以参考Docker 镜像加速 配置docker的国内镜像。
在任务栏点击Docker Desktop应用图标，打开Perferences个人设置，切换到Docker Engine标签页，可以看到默认的配置：
我们在这个配置文件中添加镜像的配置，配置内容如下：
{
"debug": true,
"experimental": false,
"registry-mirrors":["https://docker.mirrors.ustc.edu.cn","https://hub-mirror.c.163.com","http://f1361db2.m.daocloud.io"]
}
添加完成后，点击「Apple & Restart」应用并重启后，再看看docker的镜像信息：
sh
$ docker info [21:35:47]

提示
你也可以直接修改docker的配置文件，配置文件位置为~/.docker/daemon.json 。
sh
$ cat ~/.docker/daemon.json
{"debug":true,"experimental":false,"registry-mirrors":["https://docker.mirrors.ustc.edu.cn","https://hub-mirror.c.163.com","http://f1361db2.m.daocloud.io"]}在Linux系统上面对应的配置文件为/etc/docker/daemon.json。
配置了国内镜像站后，你后续使用docker pull下载docker镜像时，可以明显发现速度快多了。
搜索docker镜像
sh
# 搜索镜像时的帮助信息
$ docker search --help
Usage: docker search [OPTIONS] TERM

$ docker run hello-world
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

访问http://localhost:8080/svn/testinfo/，可以正常打开页面提示框，输入用户名admin和密码admin,可以正常打开SVN页面，并看到页面显示testinfo - Revision 0: /，说明Apache和SVN运行正常。
访问http://localhost:9001/，不能正常显示，原因不明。
普通用户运行docker命令
如让meizhaohui这个普通用户能够运行docker命令，则只需要执行以下命令即可：
sh
$ sudo gpasswd -a meizhaohui docker这样就将普通用户加入到docker组中，然后退出远程连接，再重新连接服务器，此时就可以以普通用户执行docker命令了。
