How to Use Different Ports for Multiple Docker Apps?

When you're setting up your port mappings for Docker, remember that it's defined as `host:container`. You can choose almost any unused port for the host, like `8181:80`. The important part is knowing that the container's internal port usually shouldn't be changed unless necessary. Most images have a default internal port (like `80`), and that's what you'll want to map to an external port that’s not already in use. So you might set it as `8080:80`, `8181:80`, or various other combinations, just avoid anything like `80:8080`. This way, you can run multiple apps without conflicts!

Could you share a bit more about your specific setup? For example, what ports are you using for your outside (host) and inside (container)? It might help to clarify if you're using something like `8081:80` for one app and `8080:80` for another. I had similar issues trying to run qBittorrent and Immich together, both wanted `8080`, and it was tricky until I figured out how to map them to different ports. There's definitely a way to get both running without too much hassle!
