How can I pass information between two running files from Procfile Heroku?

Question

Python

I need Heroku hosting to pass information between two running files, one responsible for the discord bot, and the other for the website on which the discord bot will be configured.

The website should take information from another file that is connected to the discord bot using the discord-ext library -ipc, but it does not do this on the hosting

Procfile:

worker: python bot.py
web: gunicorn -k uvicorn.workers.UvicornWorker main:app

error:

21-12-09T17:16:43.379263+00:00 app[web.1]: File "/app/main.py", line 53, in dashboard
2021-12-09T17:16:43.379263+00:00 app[web.1]: guild_count = await ipc_client.request("get_guild_count")

2021-12-09T17:16:43.379266+00:00 app[web.1]: raise client_error(req.connection_key, exc) from exc
2021-12-09T17:16:43.379267+00:00 app[web.1]: aiohttp.client_exceptions.ClientConnectorError: Cannot connect to host localhost:20000 ssl:default [Connect call failed ('127.0.0.1', 20000)]

As I found out, the hosting simply cannot find the file responsible for the bot's discord and gives an error, but can this be somehow avoided?

UPD:
In Procfile you need to write:

web: python bot.py & gunicorn -k uvicorn.workers.UvicornWorker main:app & wait -n

Answer 1

The 2 Dynos in Heroku can communicate via TCP/IP, so depending on what kind of communication is needed, I would choose one of:

• rest
  
• grpc
  
• Heroku Redis (queue, optional)
