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!

I can also add that if you want to run multiple programs that each have a web interface it's easy to direct each interface to the port you want instead of having to go through various config files that are different for each program or worst case having to change a hardcoded port in some software. With docker you have the same easy config options for each service you want to run. Same with storage paths. Various software stores their files at seemingly random places. With docker you just map a folder and all you files are stored there without any further configs.
