Configure APP_URL

[neezer]

Using the pro setup, I have the main application mapped to a different port because port 3000 is taken by another application already. I do this in Docker Compose like so

services:
  meme_search_pro:
    ports:
      - 3112:3000

However, it appears that the text-to-image generator expects (via hard-code) to always find the main app at port 3000:

meme-search/meme_search_pro/image_to_text_generator/app.py

Line 15 in 5b15859

APP_URL = "http://host.docker.internal:3000/image_cores/"

This generates failed requests when trying to use the image to text functionality:

2025-01-07 20:29:54,879 - INFO - Job added to queue: image_core_id=9 image_path='software/proxy2.jpg'

(connect timeout=None)'))

(Nothing is listening on 3000--the other app I have on that port is stopped during this test).

Can this be changed to read from an environment variable instead of a hard-code?

Adding a .env file for custom port mappings is certianly doable! Would you like to submit a PR to get it started? Port specifications in a .env would need to be read by both the app and image-to-text containers.

As for your current setup - if you have stopped your other process running on 3000 then the port mapping

ports:
  - 3000:3000

in the compose file should work. Can you confirm?
