Test/测试 devel-su docker run hello-world
This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits. / 这个命令会下载一个测试镜像，如果执行成功会打印如下信息
[root@Sailfish nemo]# docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 255483503861: Pull complete Digest: sha256:4b8ff392a12ed9ea17784bd3c9a8b1fa3299cac44aca35a85c90c5e3c7afacdc 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. (arm64v8) 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
