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.

Couldn't you just lazy build your own images if you don't trust the source?
Even then most of these containerized apps can be run perfectly fine as a host binary, you just have to make your own start script and a systemd unit which isn't that bad.
You could then build a completely custom image if you'd like, or move it into a VM if you don't like the idea of running it baremetal.
