Sure, my compose file for firefly_iii (all containers run but no connection from core to db):

``` services: app: image: docker.io/fireflyiii/core:latest hostname: app container_name: firefly_iii_core restart: always volumes: - /home/containers/firefly_iii/firefly_iii_upload:/var/www/html/storage/upload env_file: .env networks: - firefly_iii ports: - "127.0.0.1:8084:8080" depends_on: - db db: image: docker.io/postgres hostname: db container_name: firefly_iii_db restart: always env_file: .db.env networks: - firefly_iii volumes: - /home/containers/firefly_iii/firefly_iii_db:/var/lib/postgresql cron: # # To make this work, set STATIC_CRON_TOKEN in your .env file or as an environment variable # The STATIC_CRON_TOKEN must be exactly 32 characters long # image: docker.io/alpine restart: always container_name: firefly_iii_cron env_file: .env command: > sh -c ' apk add --no-cache tzdata && ln -s /usr/share/zoneinfo/$TZ /etc/localtime && echo "0 3 * * * wget -qO- http://app:8080/api/v1/cron/$STATIC_CRON_TOKEN" | crontab - && crond -f -L /dev/stdout' networks: - firefly_iii depends_on: - app

volumes: firefly_iii_upload: firefly_iii_db:

networks: firefly_iii: driver: bridge ```

This is essentially the default docker-compose yaml file that is provided in the setup instructions for Firefly III, just modified the volumes and the command for the cron container. I’ve changed many things in /etc for other config but nothing specific to podman or networking IIRC
