DockerはopenSUSEで公式リポジトリでサポートされており，新たにリポジトリを追加することなく容易にインストール可能である．

# zypper install docker
# systemctl start docker.service

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

opensuseをインストールすればよいかと思ったが，Tagが存在しない．(2021/01/10現在)

# docker pull opensuse

Using default tag: latest
Error response from daemon: manifest for opensuse:latest not found: manifest unknown: manifest unknown

opensuse/leapのほうが公式にサポートされている？感じがしたためこちらをインストール．Official [OK]が表示されないのが気になるが，Docker hubを見たところ公式がリリースしているように見える．

# docker pull opensuse/leap:15.2
