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:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. 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.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Curious to know what the experiences are for those who are sticking to bare metal. Would like to better understand what keeps such admins from migrating to containers, Docker, Podman, Virtual Machines, etc. What keeps you on bare metal in 2025?

I use k3s and enjoy benefits like the following over bare metal:

  • Configuration as code where my whole setup is version controlled in git
  • Containers and avoiding dependency hell
  • Built-in reverse proxy with the Traefik ingress controller. Combined with DNS in my OpenWRT router, all of my self hosted apps can be accessed via appname.lan (e.g., jellyfin.lan, forgejo.lan)
  • Declarative network policies with Calico, mainly to make sure nothing phones home
  • Managing secrets securely in git with Bitnami Sealed Secrets
  • Liveness probes that automatically “turn it off and on again” when something goes wrong

These are just some of the benefits just for one server. Add more and the benefits increase.

Edit:

Sorry, I realize this post is asking why go bare metal, not why k3s and containers are great. 😬
