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.

Since you care about security, you wouldn't do that anyway. Not to mention there's also rootful Podman, when you need that level of access.
I'd recommend an RPM-based distro with Podman, the few times I've tried Podman on a deb distro, there's always been something wonky. It's been a while, though.
Does Podman work well when you have multiple rootless containers that you want to communicate securely in a least-privilege configuration (each container only has access to what it needs)? That is the one thing I couldn't figure out how to do well with Podman.
Yes, you can easily do that. Set the container name and make them on the same network. Used caddy and whole bunch of Selfhostable services with it and I reverse proxy as
