To run and generate a run configuration for the backend in IntelliJ you can open api/src/main/java/club/mondaylunch/gatos/api/ApiApplication.java and press the play button.

The API will be available at http://localhost:8080.

Building for Production

This repository comes equipped with CI to automatically build production Docker images from the main branch.

To build this yourself, simply run:

docker build -t ghcr.io/mondaylunch/gatos-backend-api:master -f Dockerfile.api .

You may want to use a different tag, but this will replace your deployment image if you are using the default configuration.
