Selfhosted
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:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
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.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

As with most things homelab related, there is no real "right" or "wrong" way, because its about learning and playing around with cool new stuff! If you want to learn about different file systems, architectures, and software, do some reading, spin up a test VM (or LXC, my preference), and go nuts!
That being said, my architecture is built up of general purpose LXCs (one for my Arr stack, one for my game servers, one for my web stuff, etc). Each LXC runs the related services in docker, which all connect to a central Portainer instance for management.
Some things are exceptions though, such as Open Media Vault and HomeAssistant, which seem to work better as standalone VMs.
The services I run are usually something that are useful for me, and that I want to keep off public clouds. Vaultwarden for passwords and passkeys, DoneTick for my todo-list, etc. If I have a gap in my digital toolkit, I always look for something that I can host myself to fill thay gap. But also a lot of stuff I want to learn about, such as the Grafana stack for observability at the moment.
Thank you.
I guess I have more reading to do on Portainer and LXC. Using an RPi with DietPi, I didn’t have the need to learn any of this. Now is a good time as ever.
But generally speaking, how is a Linux container different (or worse) than a VM?
An LXC is isolated, system-wise, by default (unprivileged) and has very low resource requirements.
Separating each service ensures that if something breaks, there are zero collateral casualties.
A VM is properly isolated and has it's own OS and kernel. This improves security at the cost of overhead.
If you are starved for hardware resources then running lxcs instead of vms could give you more bang for the buck.
