Dockerfile

# Production Dockerfile
# 
# This is used by "register_containter_image.yaml" GH action to
# 1. build a production container image that will
# 2. be registered on GHCR and subsequently
# 3. used by terraform to deploy the app

# Build image
# -----------

# so it must be present in the environment when we run `empirica bundle`.
ENV TEST_CONTROLS=${TEST_CONTROLS}

# Vite bundling can exceed Node's default heap limit inside containers.
# Allow more heap so `empirica bundle` can complete on typical dev machines.

RUN empirica bundle



# Final image
# -----------
# Already in the base image:
# - curl to install empirica and upload data
# - ca-certificates for the https connection
# - rsync for for the server build step
#
# Need to install:
# - nano to facilitate small changes on the server
# - git (for eventually syncing stuff that way)
