镜像
Linux 操作系统由内核空间和用户空间组成。
- rootfs，用户空间的文件系统是 rootfs，包含我们熟悉的 /dev, /proc, /bin 等目录。 对于 base 镜像来说，底层直接用 Host 的 kernel，自己只需要提供 rootfs 就行了。
- bootfs，内核空间是 kernel，Linux 刚启动时会加载 bootfs 文件系统，之后 bootfs 会被卸载掉。不同 Linux 发行版的区别主要就是 rootfs。
最小的镜像
bash
[root@docker ~]# docker pull hello-world
[root@docker ~]# docker images
[root@docker ~ 14:19:06]# 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
