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 upgradecan 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
