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!

If you're OK with a little more power usage (like 10W instead of 3-5W), you can buy a mini PC from Dell/Lenovo/HP with a 7th gen Intel CPU for about $50-70 on ebay, with storage and RAM included. As a bonus you also get a case, power supply, cooling, etc.. which you have to buy extra for the Pi.

It'll be significantly faster in every way, with a lot more options for expansion if needed. The Pi 3 is very slow for even the most basic tasks, even just running apt upgrade can take several minutes or more for a few package updates.

i’ve got a used dell optiplex laying around for any bigger projects so a pi would be for tinkering with and small scale stuff. I didn’t have a good grasp of how slow it would run though thank you

A mini-pc with an Intel N100 will be a little more expensive (I bought one for ~150€) but it's about 5-6 times faster than the Pi and mine also came with 16gb of RAM and a 500gb SSD. It requires very little power and because of that, it's also very quiet. AV1 decode is also great if you plan to run something like Kodi on it or you want to do transcoding from an AV1 video with Jellyfin (I haven't migrated those to it yet, so I don't know how well it works in practice). I'm not sure but it might not even be a lot more expensive than a Pi with 8gb of RAM and an additional 500gb SSD.
