De eerste stappen met docker. Hoe krijg je de basis aan de praat:
- Installeer docker via YaST
- Check of de groep docker is aangemaakt tijdens installatie, zoniet maak haar
- Voeg (alle) gebruikers (incl. jezelf) toe aan de groep docker
- Log uit, en log opnieuw in.
De software is er, de rechten van gebruikers staan nu goed, dus testen of het werkt:
docker run hello-world
De output zal er ongeveer als volgt uit zien:
arjan@arjanpc:> docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 0e03bdcc26d7: Pull complete Digest: sha256:1a523af650137b8accdaed439c17d684df61ee4d74feac151b5b337bd29e7eec Status: Downloaded newer image for hello-world:latest 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/ For more examples and ideas, visit: https://docs.docker.com/get-started/ arjan@arjanpc:>
