# Configuration environment variables:
# - DATAFLOW_VERSION and SKIPPER_VERSION specify what DataFlow and Skipper image versions to use.
# - STREAM_APPS_URI and TASK_APPS_URI are used to specify what Stream and Task applications to pre-register.
# - HOST_MOUNT_PATH and DOCKER_MOUNT_PATH are used to set the host and docker mount folders.
#   If not set HOST_MOUNT_PATH defaults to the local host folder where the docker compose is being started.
#   If not set DOCKER_MOUNT_PATH defaults to /root/scdf on dataflow-server and skipper containers.
#   Example to mount the local Maven repository: HOST_MOUNT_PATH=~/.m2/repository/ DOCKER_MOUNT_PATH=/root/.m2  docker-compose up
#
# Exposed container ports:
# - 9393:9393               - Data Flow server port (http://localhost:9393/dashboard)
# - 7577:7577               - Skipper server port (http://localhost:7577/api)
# - 20000-20105:20000-20105 - Port range for all deployed stream applications. That means you can reach the
#                             application's actuator endpoints from your host machine.
