There is more to do in terms of documentation. We need to rewrite Getting started web if this is merged.

isn't this missing our meilisearch and poppler services? I feel like it could be useful to have those even in a dev environment.

[davidagardh]

I intentionally left them out, but we can discuss if that's the right choice. In my opinion, most common development tasks don't need them. I'm choosing to prioritize keeping the default setup small over having a production-like development environment. Our current setup is also a compromise. It doesn't include scheduler-service or shlink in the default dev workflow and minio requires extra configuration.

[Tomas-Ka]

Reasonable, but I do believe the search function is highly useful when debugging mostly anything, since it allows a user to easily traverse the webpage, and make simple queries as to what data is loaded (Members, Positions and so on). With that said Meilisearch requires to be seeded when started though which I don't believe most people do, so it may be unnecessary as you say.

[davidagardh]

I added a second configuration that includes search, but without is default.

Haven't tested the devcontainer integration, but the image itself works great
