A very minimalistic Telegram bot that helps manage events. The idea is very simple - create an event, then participants of the chat respond if they join or not. Initially, it was made for organizing football games.
- /i - Add yourself as a participant to the current event. Add name as an argument to add someone.
- /cant - Remove yourself from participants of the current event, pass the position number to remove someone.
- /event - Display the list of participants for the current event.
- /new - Create a new event, only one active event is supported at the moment, creating a new one will close the existing one.
The bot is written in GO to try out the language.
The bot uses GCP Datastore.
Deployment is not automated. It's necessary to enable API for datastore and register secrets TG_KEY - token provided
by Telegram, and TG_WEBHOOK_SECRET - random secret for making webhook url safe. Telegram allows to register webhook
programmatically, so it can be easily rotated.
New service version can be deployed to GCP Cloudrun using the cli from the repository root.
gcloud run deploy `NAME` --source . --project `PROJECT` --region `REGION` --set-secrets TG_KEY=TG_KEY:latest --set-secrets TG_WEBHOOK_SECR
ET=TG_WEBHOOK_SECRET:latest --allow-unauthenticated
Exit code 3 indicates initialization error, check the logs for details.
