gitroomhq/postiz-docker-compose ? reverse-engineered prompt

Build me a simple Docker Compose setup for running Postiz locally or on a server.

I want one easy command to start everything, with a normal production compose file and a separate dev one if that makes sense. The app should be configurable through environment variables, either directly in the compose file or through a mounted env file, and it should be clear where I’m supposed to put my settings. Please make it so I can clone the repo, run Docker Compose, and then open Postiz in the browser on port 4007.

If there are any important upgrade steps or migration notes, include them in the setup so I don’t break an existing install. Keep it straightforward and make sure the containers come up cleanly with sensible defaults. If you need to check the current Postiz docs online for the latest config values, go ahead and do that.
