还是先丢出官方的文档，学东西还是尽可能的看官方的文档，但是说真的看这个东西吧，又有点看不动，但是还是尽力的看！

好了，我来说说一些基本的比较常用的命令，我们先来入个门，等到学的差不多了，在看官方的这个文档，就会好很多！
1.镜像基本命令
查看镜像
docker images #查看镜像
我们也可以在后面跟一个 --help来查看它后面可以跟的一些参数，我这里就不弄了
[root@dingqisui ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
hello-world latest fce289e99eb9 16 months ago 1.84kB
# 列出所有的镜像，这个是上次安装docker时测试用的hello-word的镜像
REPOSITORY 镜像的仓库源
TAG 镜像的标签（版本，latest最新版本）
IMAGE ID 镜像的id（想想自己的身份证号）
CREATED 创建时间
SIZE 大小
搜索镜像
docker search 镜像名 # 搜索镜像
这个命令表达的就是这个意思：
地址：
https://hub.docker.com/
下载镜像
docker pull mysql
不指定就是下载最新的：
常用的是下载指定版本的：
[root@dingqisui ~]# docker images

删除镜像
使用docker rmi 删除，后面跟参数，告诉ta怎么删，删哪里的：
docker rmi -f id(前面提到的像你的身份证的一样的东西)
docker rmi -f id id id id ...删除多个
docker rmi -f $(docker images -aq) 删干净
[root@dingqisui ~]# docker images
