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!
Doesn’t that mean that docker containers use up much more resources since you’re installing numerous instances & versions of each program like PHP?
Oh, sure, the bloat on your images requires resources from the host.
There is the option of sharing things. But, obviously that conflicts a bit with maintaining your environments isolated.
