# Docker compose recipe for InvenTree development server
# - Runs PostgreSQL as the database backend
# - Uses built-in django webserver
# - Runs the InvenTree background worker process
# - Serves media and static content directly from Django webserver

# IMPORANT NOTE:
# The InvenTree development image does not clone source code from git.
# Instead, it runs from source code on your local machine.
# The django server will auto-detect any code changes and reload the server.

# If you have cloned the InvenTree git repo, and not made any changes to this file,
# then the default setup in this file should work straight out of the box, without modification

services:

    # Database service
    # Use PostgreSQL as the database backend

    #        - 8000:80
    #    volumes:
    #        # Provide ./nginx.dev.conf file to the container
