Hey everyone! I'm pretty new to the world of Docker, despite taking some courses and watching videos. I'm trying to set up an open-source data workflow using Apache Superset, Apache Airflow, and PostgreSQL. I've put together a Docker Compose YAML file with the necessary configurations thanks to some help, but now I'm stuck. I've deployed it on my Raspberry Pi 5 via Portainer, but I can't access the services. I've spent about six hours trying to figure it out – I can launch Superset and Airflow through VS Code and Docker Desktop, but I can't connect a database in Superset. Is setting this up too ambitious for a newbie, or does anyone have tips to help me get this working? Thanks a lot in advance!

Seems like you might be trying to open the services incorrectly. Are you using the correct IP and port? If you’re expecting to use the names for the services with Traefik, just ensure you have the proper DNS settings pointing to your reverse proxy. Otherwise, try accessing them directly via IP:port.
I’d advise against relying too much on AI for setting up your environment, especially as a beginner. It’s better to focus on straightforward tutorials from the Docker official docs. Get a basic Docker image running, work on understanding port mapping, and then build up from there with one service at a time. This way, you’ll grasp the concepts better!
Starting big can be overwhelming! Instead of trying to build an entire system with multiple components, maybe focus on getting one service running smoothly first. Once you understand how Docker works, you can gradually add complexity. Just experiment with simple setups for now, and take the time to learn the basics before diving into the intricate details.
Thanks! I'll definitely check the Docker documentation and start small with one service to get the hang of it.
