• Go to Telegram and search for: ocr_marketalert

• Use /help to get the command list.

How to use the repo

• Open a Terminal window.
• Change to the parent directory you use to store your repos.
• Then run these commands:

git clone https://github.com/tomkat-cr/market_alert_bot.git
cd market_alert_bot

• All the magic is in the index.py file on the api directory...

How to deploy to fly.io

Create the BOT on Telegram:

• Go to Telegram
• Search for: botfather
• Double click on the @botfather entry
• Click on the Start link at the bottom of the chat section.
• Use /newbot command to create the BOT.
• Follow on-screen instructions to assign a BOT user name, BOT name, etc. Please use a different name than @ocr_marketalert_bot ;)
• That the end of the process, copy the Telegram BOT Token and store it in a secure place.

Create the .env file:

• Run this command:

cp .env-example .env

• Edit the .env file and paste the Telegram BOT Token on the TELEGRAM_BOT_TOKEN variable.

Create the App on Fly.io by running this command:

sh run_fly_io.sh create_app

Finally deploy it running this command:

sh run_fly_io.sh deploy

NOTE:
The api/Dockerfile has the magic to run the BOT on Fly.io. It creates a docker container with python setup, perform a pip install and run python index.py. That's the way Fly.io works.
