What's the deal with Docker? (lemmy.zip)

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!

Avoid Docker as much as possible. It gives you a quick way to run apps, but in a way that you can't see what is going to be installed.

It is also double resource heater.

And it has many frequent vulnerabilities.

    You can look at the Dockerfile and see every single step that goes into building a particular image.

    It is also double resource heater.

    That's patently false.

    And it has many frequent vulnerabilities

    Dawg have you ever actually used docker?
