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

使用 Shell 脚本进行安装
脚本需要运行 root 或具有 sudo 特权。因此,在运行脚本之前,应仔细检查和审核脚本。
这些脚本尝试检测 Linux 发行版和版本,并为您配置软件包管理系统。此外,脚本不允许您自定义任何安装参数。从 Docker 的角度或您自己组织的准则和标准的角度来看,这可能导致不支持的配置。
