Requirements

• Docker

Installation and usage

1. Pull the Docker image from the DockerHub:

   docker pull aleg94/telegram-forwarder
   

2. Create a Telegram session by getting developer's api id and api hash from here and running the command:

   docker run -it --rm aleg94/telegram-forwarder python ./scripts/create_session.py --api-id <api-id> --api-hash <api-hash>
   

   Follow the on-screen instructions and enter your confirmation code and password (if two-factor authentication is enabled).

3. Run the image in a container providing the following environment variables:

   • API_ID: the api id associated with your Telegram account
   • API_HASH: the api hash associated with your Telegram account
   • SESSION: the session obtained in step 2
   • INPUT_CHATS: comma separated list of chat's ids or usernames that you'd like to forward messages from (must be present on dialogs)
   • OUTPUT_CHATS: comma separated list of chat's ids or usernames that you'd like to forward messages to (must be present on dialogs)
   • MESSAGE_PATTERN: a regular expression that messages must match to be forwarded
   
   

   docker run --name telegram_forwarder -d
     -e API_ID=<api-id>
