- Use scratch base image (< 20MB final vs ~50MB alpine)
- Add BuildKit cache for go modules and build cache
- Selective COPY (cmd, internal, migrations, docs) instead of COPY . .
- Remove HEALTHCHECK (not supported by Podman OCI)
- Update .gitignore with more binary patterns
- Optimize .dockerignore to exclude tests and binaries
- Updated EXPOSE from 8080 to 8521
- Updated HEALTHCHECK to check port 8521
- Updated default ENV PORT from 8080 to 8521
This fixes the deployment health check issue where the container
was expecting port 8080 but the app was configured to run on 8521.
