TGForwarderClient - forward messages from channels to chats in Telegram

Tutorial

1. Visit Telegram Apps API and login with your Telegram Account.
2. Fill out the form to register a new Telegram application.
3. After registration you get an API key. It consists of two parts: api_id and api_hash - set those as env variables to $API_ID and $API_HASH (you can save them for persistence to .env file).
4. Run the app interactively: docker run -e API_ID -e API_HASH -i ghcr.io/qqalexqq/tgforwarderclient:latest export
5. Input your data:

Is "+9876543210" correct? (y/N): y
The confirmation code has been sent via Telegram app
Enter confirmation code: 123456
The two-step verification is enabled and a password is required
Password hint: None
Enter password (empty to recover): verysecurepassword
---
abcdefghijklmnopqrstuvwxyz (ver long string)

6. Copy the last long string from the output. Set it to an env var $SESSION_KEY.

7. Set forwarding variables in docker-compose.yml: BOT_CHANNELS (from where we forward) and BOT_CHATS (to which chats we forward). Examples are provided in the file.

8. After all things done you can start the container:

docker-compose build
docker-compose up -d
