compose.yaml

# Everything dbclone needs, with nothing installed on the host but Docker:
#
#   docker compose up -d                 # local MongoDB + MySQL + Postgres from the official images
#   docker compose run --rm dbclone      # the CLI itself, talking to them over the Docker socket
#
# Ports, container names and the local root password can be overridden from the
# environment (DBCLONE_MONGO_PORT, DBCLONE_MYSQL_PORT, DBCLONE_POSTGRES_PORT,
# DBCLONE_MONGO_CONTAINER, DBCLONE_MYSQL_CONTAINER, DBCLONE_POSTGRES_CONTAINER,
# DBCLONE_LOCAL_PASSWORD). The password only guards databases
# on your own machine; dbclone reads it from the containers and never asks for it.
