AWS Lambda Passport Status Checker with Telegram Notifications

Overview

This project involves deploying a Python script to AWS Lambda, which checks the status of a passport application at regular intervals and sends updates via Telegram. The script is triggered every 15 minutes to verify if there's a new update on the status page and notifies the user accordingly.

Prerequisites

Before you start, you need to have the following:

• An AWS account. You can create it here.
• Basic understanding of AWS services, especially Lambda and CloudWatch.
• Terraform installed on your computer.
• Python installed on your computer.
• Telegram account and a Telegram bot. Here's how to create a Telegram bot.

Setup and Deployment

Step 0: Clone the Repository

1. Clone the repository:
   • Clone this repository to your local machine.

Step 1: AWS Configuration

1. AWS CLI Setup:
   • Install AWS CLI: AWS CLI Installation Guide.
   • Configure AWS CLI with your credentials: Run aws configure and enter your AWS Access Key, Secret Key, and default region.

Step 2: Terraform Configuration

1. Install Terraform:

   • Follow the instructions here to install Terraform.

2. Initialize Terraform:

   • In the directory with your Terraform files (main.tf, variables.tf, terraform.tfvars), run:

     terraform init
     

Step 3: Setting Up Terraform Variables

1. Create terraform.tfvars file in the same directory as your Terraform files.:
   • Open terraform.tfvars.
   • Set the values for telegram_token, telegram_chat_id, passport_series, and passport_number with your own values.

Step 4: Deploying with Terraform

1. Run Terraform Apply:
   • Execute:

     terraform apply
     

   • Review the plan and type yes to proceed.

Step 5: Verification

1. Check AWS Lambda:

   • Log into your AWS Console.
   • Go to the Lambda service and check if your function (UAPassportCheck) exists.
   • You can test the function manually here.

2. Check CloudWatch Events:

   • In the AWS Console, navigate to CloudWatch.
   • Verify that there's a rule set to trigger your Lambda function every 15 minutes.

3. Check Telegram Bot:

   • Send a message to your Telegram bot.
   • Ensure you receive updates from the Lambda function.

Troubleshooting

• Lambda Function Errors: Check the logs in CloudWatch for any errors during Lambda execution.
• Terraform Errors: Ensure all Terraform configuration files are correct and all required values are provided.
• Telegram Bot Issues: Verify that the bot token and chat ID are correct.

Conclusion

Your AWS Lambda Passport Status Checker is now set up and will notify you via Telegram every 15 minutes if there's an update on the passport status page.
