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.

all the containers change IP addresses frequently. For home assistant a static IP address of the proxy manager is mandatory in order to reach it. For jellyfin it is useful to see which device accesses jellyfin. If the IP always changes, it doesn't work properly.

How do I fix a container IP with podman compose (or docker)

The bigger issue (IMO) is, that you now have a hard requirement on the startup order of your services. If another one happens to get the IP assigned automatically befor your service starts that requests it explicitly, you now have a conflict that you manually have to resolve.

DNS is the only sane solution here.

DNS can also give you some headaches. If you also need to reach other things on the LAN by name, or want to have a mesh VPN going with Tailscale, now you have to juggle three DNS domains.

I meant DNS within your container network. Exposed stuff should be mapped to host ports.
