# syntax=docker/dockerfile:1.2
#
# Build command (local build):
#
#  DOCKER_BUILDKIT=1 docker build -t dashboards:latest --build-arg build_type=local --ssh default .
#
# Build arguments
#  - build_type, if set to "local", then the dashboard will run without various additional parameters
#        that are specific to a production build.
#
# To run locally:
#
#  docker run -it --rm --network host dashboards:latest
#
# The parameter --network host attaches the dashboard to your localhost, meaning the dashboard can now be
# accessed on the default port 5006. Furthermore, the dashboard is able to communicate to other services
# running on localhost. If you have an instance of the database running on localhost this can now be used.
