Dockerfile

# The default deploy instructions (https://biffweb.com/docs/reference/production/) don't
# use Docker, but this file is provided in case you'd like to deploy with containers.
#
# When running the container, make sure you set any environment variables defined in config.env,
# e.g. using whatever tools your deployment platform provides for setting environment variables.
#
# Run these commands to test this file locally:
#
#   docker build -t your-app .
#
# Run this command if building from arm macbook
#
#   docker buildx build --platform linux/amd64 -t your-app .
#
#   docker run --rm -e BIFF_PROFILE=dev -v $PWD/config.env:/app/config.env your-app
