I'm new to Docker and I'm having a real tough time wrapping my head around it. I've taken some courses and watched tutorials, but now I'm stuck trying to create an open-source data workflow project using Apache Superset, Apache Airflow, and PostgreSQL.
I came up with a Docker Compose YAML file, but when I deployed it through Portainer on my Raspberry Pi 5, I couldn't figure out how to access the services. I mean, I've spent six hours on this and nothing seems to work. I even tried creating a project with Docker Desktop, but ran into issues connecting Superset to PostgreSQL. Am I being too ambitious trying to manage all of this with Docker? Any tips or advice would be really appreciated!

To access your services, make sure you're using the correct IP address and port. If you're relying on Traefik, check that your DNS settings are correctly pointing to your reverse proxy. It can be a little confusing at first, but once you nail down the basics, it gets easier. Also, ditch any unnecessary components like Traefik for now — focus on the fundamentals first!
Real talk — relying solely on AI tools like ChatGPT for setup can lead to more issues, especially if you're new. Focus on manual setup first, like running single containers and understanding port mapping. Once you've got a single service running smoothly, then start thinking about Docker Compose. Remember, the learning process is where the value is!
Solid advice! I’ll try building it up step by step instead.
Honestly, starting simple is key when you're learning Docker. Instead of trying to tackle everything at once, focus on getting one service to work, like PostgreSQL. Once that's up and running, gradually add other components. Jumping into complex setups can be overwhelming and can make troubleshooting a nightmare. Check out the official Docker tutorials for some guided learning!
Agreed! It's easy to get lost in all the complexity. Baby steps will help you build confidence.
Thanks for the tip! I’ll go back and check my setup.
