Deployment

Why would you want to do that?

If you want to somehow deploy another same bot:

• Configuration is currently a bit hard-coded. Change code according to your needs
• Specify these environment variables
  • BOT_SECRET: A secret string to use in webhooks
  • TELEGRAM_KEY: Your Telegram bot key
  • DATABASE_URL: A Postgresql connection URL
  • ARMED: true if you want the bot to send Telegram messages (or any non-reply requests to the Telegram servers at all)
  • PORT: Port to listen on. Defaults to 5000
• Set webhook to .../webhook/$BOT_SECRET using the Telegram Bot API manually.
• Periodically POST to /update with json like { "secret": "<bot secret>", "action": "update" }. An update will run in the background after some delay (0 to 60 seconds random).
