I never understood how to use Docker, what makes it so special? I would really like to use it on my Rapsberry Pi 3 Model B+ to ease the setup process of selfhosting different things.

I’m currently running these things without Docker:

  • Mumble server with a Discord bridge and a music bot
  • Maubot, a plugin-based Matrix bot
  • FTP server
  • Two Discord Music bots

All of these things are running as systemd services in the background. Should I change this? A lot of the things I’m hosting offer Docker images.

It would also be great if someone could give me a quick-start guide for Docker. Thanks in advance!

    Yeah, and it also requires quite many options, some with harder-to-predict outcomes. For example RootDirectory can be used to effectively chroot the process, but that carries implications such as the application not having access to CA certificates anymore, which in general in containers is a solved problem.
