用Hello World校验Docker的安装
用Docker运行Hello World镜像,命令如下:- # docker run hello-world
- Unable to find image 'hello-world:latest' locally
- latest: Pulling from hello-world
- 535020c3e8ad: Pull complete
- af340544ed62: Pull complete
- Digest: sha256:a68868bfe696c00866942e8f5ca39e3e31b79c1e50feaee4ce5e28df2f051d5c
- 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.
- 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 Hub account:
- https://hub.docker.com
- For more examples and ideas, visit:
- https://docs.docker.com/userguide/
复制代码 可见,Docker注册服务器从Docker Hub获取到最新的Hello World镜像,下载到了本地。可以再次运行Hello World镜像。- # docker run hello-world

复制代码 可见,Hello World镜像运行成功,Docker的安装也没有问题。 |
