# Validate the configuration (does not start anything):
docker compose -f compose.yaml config

# Pull images and start in the background:
docker compose -f compose.yaml pull
docker compose -f compose.yaml up -d

# Check status and follow logs:
docker compose -f compose.yaml ps
docker compose -f compose.yaml logs -f

# Stop and remove (named volumes are kept):
docker compose -f compose.yaml down
