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!
I use proxmox to run debian VMs to run docker compose “stacks”.
Some VMs are dedicated to an entire servicecs docker compose stack.
Some VMs are for a docker compose of a bunch of different services.
Some services are run across multiple nodes with HA VIPs and all that jazz for “guaranteed” uptime.
I see the guest VM as a collection, but there is only ever 1 compose file per host.
Has a bit of overhead, but makes it really easy to reason about, separate VLANs and firewall rules etc
