此处通过运行hello-world镜像来测试Docker是否安装成功。命令如下:
sudo docker run --rm hello-world
假如安装成功,会输出以下信息。假如没有设置镜像并且没有魔法则不会出现Hello from Docker!的提示,但只要能看到This message shows that your installation appears to be working correctly,说明安装成功。
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
