# Set the TAG environment variable to set the image tag e.g.
#   TAG=testing docker-compose build ...
#
# Set the ENABLE_TESTS build argument to support test functionality in the containers e.g.
#   docker-compose build --build-arg ENABLE_TESTS=1
#
# DBCONN is a database connection string that is passed straight through to the Flask container.
# However, if we're talking to a SQLite database, we also need to mount the file into the container.
# This is done via the SQLITE variable, but since Docker doesn't allow any way to do things conditionally,
# it needs to be set even if it's not being used :-/
#
# See the run-containers.sh script that manages all of this.
