InvenTree/contrib/container/Dockerfile

# The InvenTree dockerfile provides two build targets:
#
# production:
# - Required files are copied into the image
# - Runs InvenTree web server under gunicorn
#
# dev:
# - Expects source directories to be loaded as a run-time volume
# - Runs InvenTree web server under django development server
# - Monitors source files for any changes, and live-reloads server
