You just need the docker and docker-compose packages. You make a
docker-compose.ymlfile and there you define all settings for the container (image, ports, volumes, ...). Then you rundocker-compose up -din the directory where that file is located and it will automatically create the docker container and run it with the settings you defined. If you make changes to the file and run the command again, it will update the container to use the new settings. In this commanddocker-composeis just the software that allows you to do all this with thedocker-compose.ymlfile,upmeans it's bringing the container up (which means starting it) and-dis for detached, so it does that in the background (it will still tell you in the terminal what it's doing while creating the container).
