在新主機(jī)上首次安裝Docker Engine之前，需要設(shè)置Docker存儲庫。之后，您可以從存儲庫安裝和更新Docker。
設(shè)置存儲庫
安裝yum-utils軟件包（提供yum-config-manager 實(shí)用程序）并設(shè)置穩(wěn)定的存儲庫。

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:
https://hub.docker.com/
