name: todolist

# This file starts a PostgreSQL database in a docker container, which is required for running the application and tests locally.
# It also starts pgAdmin (a web-based PostgreSQL management tool) in a second container, which lets you query the database.
#
# Usage:
#   docker compose up --detach --wait
#
# To connect to pgAdmin, open http://localhost:5050. It will automatically log in and connect to the database.
#
# To stop:
#   docker compose down
#
# To stop and remove persistent data (reset):
#   docker compose down --volumes
