@dosubot[bot] commented on GitHub (Mar 3, 2025):

To update the web port from 3000 to 4000, you need to modify the ENV PORT and EXPOSE directives in the Dockerfile. Change them as follows:

ENV PORT=4000
EXPOSE 4000

This will set the environment variable PORT to 4000 and expose port 4000 in the Docker container [1].
