命令格式：docker run 镜像名称

可以看到的是本地没有目标镜像时候，则从镜像仓库去拉取，默认拉取版本（tag）是latest

[root@DESKTOP-7ONFN16 ~]# docker run hello-world

Unable to find image 'hello-world:latest' locally

latest: Pulling from library/hello-world

Status: Downloaded newer image for hello-world:latest

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
