容器操作基础命令
容器生命令周期
启动容器
docker run 可以启动容器，进入到容器，并随机生成容器ID和名称
帮助：man docker-run
命令格式：
docker run [选项] [镜像名] [shell命令] [参数]
选项：
-i, --interactive Keep STDIN open even if not attached，通常和-t一起使用
-t, --tty Allocate a pseudo-TTY，通常和-i一起使用
-d, --detach Run container in background and print container ID,台后运行，默认前台
--name string Assign a name to the container
--rm Automatically remove the container when it exits
-p, --publish list Publish a container's port(s) to the host
-P, --publish-all Publish all exposed ports to random ports
--dns list Set custom DNS servers
--entrypoint string Overwrite the default ENTRYPOINT of the image
--restart policy
--privileged Give extended privileges to container有四种不同的policy
| policy | 说明 |
|---|---|
| no | Default is no，Do not automatically restart the container when it exits. |
| on-failure[:max-retries] | on-failure[:max-retries] Restart only if the container exits with a non-zero exit status. Optionally, limit the number of restart retries the Docker daemon attempts. |
| always | Always restart the container regardless of the exit status. When you specify always, the Docker daemon will try to restart the container indefinitely. The container will also always start on daemon startup, regardless of the current state of the container. |
| unless-stopped | Always restart the container regardless of the exit status, but do not start it on daemon startup if the container has been put to a stopped state before. |
退出容器并停止容器
exit 退出容器且容器不停止

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

大约在0.6版，–privileged 选项被引入docker。使用该参数，container内的root拥有真正的root权限。
否则，container内的root只是外部的一个普通用户权限。privileged启动的容器，可以看到很多host上的设备，并且可以执行mount。甚至允许你在docker容器中启动docker容器。
范例：使用–privileged 让容器获取 root 权限
