Dockerfile

COPY --from=prerelease /usr/src/app/.output .output

# run the app
USER bun
EXPOSE 3000/tcp
ENTRYPOINT [ "bun", "run", "start" ]

Mainly taken from the bun documentation site. I just debugged the files required in the production build. Feedback is more than welcome.

SERVER_PRESET=bun gives me issues when deploying locally but other than that works well
