Docker 官方製作了一個有趣的 Hello-world docker 映像檔,現在就來拉取下來跑起來,順便複習一下語法並看看內容吧。
docker pull hello-world
docker run hello-world
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:

這個 hello-world docker 映像檔內,簡單介紹方才你的一系列 docker 指令,其在背後做的事情:
這由官方所提供的映像檔,其評價相當不錯呢!或許這是個官方所提供的程式工具彩蛋~
