          The container must be started before installing composer dependencies.
          This is typically done by the 'deploy-image.yml' playbook which should run before this.
          
          To start the container manually:
          cd {{ application_code_dest }}
          docker compose -f docker-compose.base.yml -f docker-compose.{{ application_compose_suffix }} up -d {{ php_service_name }}
          
          Note: The container requires environment variables (DB_USERNAME, DB_PASSWORD, etc.)
          which should be set in a .env file or via docker-compose environment configuration.
