A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

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!

Dockers documentation is actually pretty good, I’d recommend taking a look at it because it’s written really well and can be used as a decent primer on learning to read documentation.

I would recommend learning docker / containerization. For your use case you likely won’t see a big benefit HOWEVER it is a good technology to know.

As far as the “why” you’d use it there are too many to list but for your use case the why I’d argue is “just so you know how to do it” and you’ll come up with your own why along the way.

Simplest why beyond “it’s a good technology to know” is that updating an app is as simple as pulling a new container and relaunching it.
