# Build an image named "inventory" with:
#   docker build --tag inventory .
#
# Then run your image with:
#   docker run -it --env INVENTORY_DISABLE_AUTH=1 --publish 8081:8081 --volume $(pwd)/inventory.db:/prog/inventory.db inventory
#
# Please note that the file "inventory.db" must exist, and be
# writable for the user in the image (uid 1000, gid 1000, you
# can change that below).
#
# Please also note that setting INVENTORY_DISABLE_AUTH to 1
# (like shown above) disables authentication and thus shall
# NEVER be used in untrusted networks (like the internet)!
#
# For more documentation and development, please see:
