       container_name: flare-db
       restart: unless-stopped
       environment:
         POSTGRES_USER: flareuser          # change if you want
         POSTGRES_PASSWORD: your-secure-password-here   #  ^f^p CHANGE THIS to something strong
         POSTGRES_DB: flaredb              # database name Flare will use
       volumes:
         - ./postgres-data:/var/lib/postgresql/data   # persistent storage
       healthcheck:
         test: ["CMD-SHELL", "pg_isready -U flareuser -d flaredb"]
         interval: 10s
         timeout: 5s
