REPOSITORY：表示镜像的仓库源
TAG：镜像的标签
IMAGE ID：镜像ID
CREATED：镜像创建时间
SIZE：镜像大小
参数：
在docker hub上搜索匹配的镜像。
输出显示：名字、描述（默认截断的）、星标数、是否官方、是否是自动化的
最多显示25个搜索结果
过滤条件：
Filter output based on these conditions:
- stars=<numberOfStar>
- is-automated=(true|false)
- is-official=(true|false)
参数：
Filter output based on conditions provided #加上面的过滤条件
Pretty-print search using a Go template
help for search
Max number of search results #修改最大搜索结果
Don‘t truncate output
举例：docker pull nginx
默认使用latest标签下载最新版
如果想要下载某个版本，需要到https://hub.docker.com/上搜索nginx，查看可用标签，使用docker pull nginx:1.19-perl等命令
?
查看镜像
删除上面下载的1.19版本的nginx
查看镜像
删除所有镜像：docker rmi -f $(docker images -q)
以centos为例
先下载centos image
参数：
-d, --detach=true|false #容器后台运行，返回容器ID
Detached mode: run the container in the background and print the new container ID. The default is false.
-h, --hostname="" #设置容器主机名
Container host name
-i, --interactive=true|false 以交互式模式运行
Keep STDIN open even if not attached. The default is false.
--name="" #为容器指定一个名字
Assign a name to the container
-P, --publish-all=true|false #随机端口映射
Publish all exposed ports to random ports on the host interfaces. The default is false.
-p, --publish ip:[hostPort]:containerPort | [hostPort:]containerPort #指定端口映射
Publish a container‘s port, or range of ports, to the host.
-t, --tty=true|false #为容器分配一个伪终端
Allocate a pseudo-TTY. The default is false.????
-i 交互式运行
-t 分配一个伪终端
-it 正常交互，类似console
-d 容器后台运行
docker ps -a 进行查看, 会发现容器已经退出
很重要的要说明的一点: Docker容器后台运行,就必须有一个前台进程.
容器运行的命令如果不是那些一直挂起的命令（比如运行top，tail），就是会自动退出的。
这个是docker的机制问题,比如你的web容器,我们以nginx为例，正常情况下,我们配置启动服务只需要启动响应的service即可。
例如service nginx start
但是,这样做,nginx为后台进程模式运行,就导致docker前台没有运行的应用,
这样的容器后台启动后,会立即自杀因为他觉得他没事可做了.
所以，最佳的解决方案是,将你要运行的程序以前台进程的形式运行
