接下来，运行我们的第一个Docker镜像"Hello,World"，执行命令`docker run hello-world`，这将下载一个官方的Docker映像，然后在容器中运行它。 **Command Line** ***** ``` $ docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 0e03bdcc26d7: Pull complete Digest: sha256:8c5aeeb6a5f3ba4883347d3747a7249f491766ca1caa47e5da5dfcf6b9b717c0 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 Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/ ``` 通过命令`docker info`查看Docker状态，顶部的几行信息告诉我们有一个没有运行的容器和一个镜像。 **Command Line** ***** ``` $ docker info Client: Debug Mode: false Server: Containers: 1 Running: 0 Paused: 0 Stopped: 1 Images: 1 ... ``` 这意味着Docker已成功安装并运行。
