# Project N.O.M.A.D. management services Docker Compose configuration
#
# This compose file defines the admin server, database, and other supporting services required to run Project N.O.M.A.D.
# You can use this with `docker-compose up -d` to start all the necessary services with a single command after installation.
#
# Note: we recommend leaving all of the environment variables as-is except for any "replaceme" values,
# which must be updated for the admin server to start successfully. The default values are optimized for ease of installation and use,
# but you can customize them as needed (e.g. changing ports, database connection details, log level, etc.)
