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/ For more examples and ideas, visit: https://docs.docker.com/get-started/ $ **一般ユーザーにDockerを使わせる [#r8eb2dfc] $ getent group | grep docker これでユーザーがまだいないことを確認。 $ sudo usermod -aG docker arqtan (arqtan ユーザーをdockerグループに追加) $ logout (リログ) $ docker run hello-world (sudo 抜きで実行、同じはろーわーるどが出たら成功)
