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.

I've used Docker a fair bit over the years because it's a simple line of code I can copy/paste to get a simple web server running.
I ran Home Assistant Supervised in Docker for many years. It was a few lines of code and then I basically had Home Assistant OS running on my Pi without it taking over the whole Pi, meaning I could run other things on it too.
That ended when HA just died one day and I had no clue how to get it running again. I spent a day trying, then just installed HA OS on the Pi instead.
Anyway I now have a Dell Optiplex and Proxmox and I've gone back to Docker. Why? Well I discovered that I could make a Linux VM and install Docker on it, then add the Docker code to install a Portainer client to it, then make that into a template.
Meaning I can clone that template and type the IP address into Portainer and now I have full access to that Docker instance from my original Portainer container. That means I can bang a Docker Compose file into the "Stack" and press go, then tinker with the thing I wanna tinker with. If I get it working it can stay, if I don't then I just delete the VM and I've lost nothing.
Portainer has made Docker way more accessible for me. I love a webui
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
