Dockerfile

# ensrainbow-data contains an already ingested DB that will be served by the ENSRainbow app
# Using a prebuilt image for ensrainbow-data (infrequently changes) reduces build time for the ENSRainbow app image
# ensrainbow-data image is only supporting amd64 arch hence define platform at the FROM statement
ARG DATA_IMAGE_PLATFORM=linux/amd64
# DATA_IMAGE_NAME is set to either "ensrainbow-data" (default) or "ensrainbow-v2-data" based on the build context.
# It can be set using the --build-arg flag when building the Docker image.
ARG DATA_IMAGE_NAME="ensrainbow-data"
