“Keep it simple”—something I keep repeating to everyone I work with. I myself have been bitten too often by the temptation to use the latest tech, even when a trusted but less “sexy” alternative was available that could do the job perfectly.

But this post could have been made a lot simpler by using SQLite. Do away with all the docker stuff, a simple file- based database will do for starters. If you need concurrent access later, it will be easy to port the DB to Postgres or similar.
