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.

It depends on what you want. Do you want containers that don't blow away your firewall? Podman is nice, but docker can be configured a little to avoid this. Want things that autostart and don't have issues with entry points that attempt to play with permissions/users? Docker or podman as root is necessary. Want reasonable compose support? Podman now needs a daemon/socket. Want to make build containers and not deal with permission/user remapping at all? Podman is really nice.
Do not attempt to use podman-compose. That app is dead.
Unfortunately if you want to make tools that will be used by other people then you must add docker support. It just owns too much of the market.
is podman-compose really dead? Their github page looks active at a glance. The tooling is so similar, I use podman for local testing, and deploy to docker, but I've also done the reverse. As long as your not using really exotic parameters its really just a drop in replacement, I've even used GPU passthrough for AI project no problem in both docker and podman. At the end of the day, they're just slightly different frontends for the same backend.
As far as docker support, its often as simple as just providing a Dockerfile, which is basically the same thing as your build scripts. These days I've often used the Dockerfile INSTEAD of the readme to find help compiling some projects.
It was dead however long ago when I submitted a PR. Still unmerged with no activity on the request so I just never went back to check.
It's good to hear that they are working on it again though, if that is the case.
