Configuration of Zimfarm local instance

Hello. I am trying to configure the local instance of Zimfarm. I have investigated the documentation, but it looks like I still need help.

Here is my docker-compose.yml

 services:
  zimit-ui:
    image: ghcr.io/openzim/zimit-ui:latest
    container_name: zimit-ui

Questions:

Image for zimit API is this one ghcr.io/openzim/zimit:zimit2 ?
Are zimfarm_dispatcher and zimfarm_backend the same or 2 different containers?
For now I can run zimfarm-ui, zimfarm_dispatcher, zimfarm_receiver, zimfarm_db, zimit-ui. BUT zimit_api, zimfarm_worker-mgr, zimfarm_task-worker are falling with errors in logs: 3.1. zimit_api: /usr/local/bin/entrypoint.sh: 3: exec: python: not found 3.2. zimfarm_task-worker:
```
usage: task-worker [-h] --task-id TASK_ID [--webapi-uri WEBAPI_URI] --username
               USERNAME [--workdir WORKDIR]
task-worker: error: argument --task-id: expected one argument
```
How should worker-mgr provide task ID to task-worker? Or should worker-mgr create task-worker containers by himself, and I do not need zimfarm_task-worker in docker-compose file? 3.3. zimfarm_worker-mgr: [2024-05-14 13:49:39,129: CRITICAL] private key is not a readable path. Where to get this private key, and for what is it used?
Is something else missing in my docker-compose.yml?
