docker-compose.yml

# Before running docker compose up for the first time,
# first copy the env.example file to .env and fill in the values.
# `cp env.example .env`
# (edit values as needed)
#
# Then, build and run with:
# `docker compose build`
# `docker compose up`
#
# Subsequently you should only need to run:
# `docker compose up`
#
# Force a full re-build with no cache from previous builds:
# `docker compose build --no-cache`
# `docker compose up`
#
# If you only changed the .env file, you can do a quick rebuild:
# `docker compose up --force-recreate`
#
# To stop, press CTRL+C (if not running in --detach mode), or run:
# `docker compose down`
