In the What are YOU self-hosting? thread, there are a lot of people here who are self-hosting a huge number of applications, but there's not a lot of discussion of the platform these things run on.
What does your self-hosted infrastructure look like?
Here are some examples of more detailed questions, but I'm sure there are plenty more topics that would be interesting:
What hardware do you run on? Or do you use a data center/cloud?
Do you use containers or plain packages?
Orchestration tools like K8s or Docker Swarm?
How do you handle logs?
How about updates?
Do you have any monitoring tools you love?
Etc.
I'm starting to put together the beginning of my own homelab, and I'll definitely be starting small but I'm interested to hear what other people have done with their setups.
I have an HP DL380 Gen8 and then a PC I bought from the local university and use as a server.
My DL380 runs ESXi. My PC runs Ubuntu on bare metal.
All of my apps are either fully VM-based (Home Assistant OS) or run in containers. Containers are far easier to build, upgrade, and migrate, and also make file management a lot easier.
I use Docker Compose. No Swarm or Kubernetes at this point.
Hopefully this is at least a good start! Let me know if you have any questions.
A combo of both. I group all my media apps like Sonarr, Radarr, SABnzbd, etc together in one compose since I consider each of them to be a part of the same “machine”, but most of my apps have their own compose.
