Pillsale Monitor Bot (AWS ECS Deployment)

A production-ready Telegram bot that monitors pillsale.fun and notifies subscribers when the site goes live.

This repository contains both:

• The application code (by Rehk Mansa)
• A full AWS ECS + Terraform infrastructure built and deployed by Emmanuel Chukwudi

---

🚀 What This Project Does

• Monitors https://www.pillsale.fun every 5 minutes
• Detects when the "Coming Soon" text disappears
• Notifies all subscribed Telegram users instantly
• Runs 24/7 on AWS ECS (Fargate)

---

🧱 Architecture Overview

AWS Services Used

• ECS (Fargate) – runs the bot container
• ECR – stores the Docker image
• VPC – private networking
• CloudWatch Logs – application logging
• IAM – task execution & logging permissions
• Terraform – Infrastructure as Code

🛠 Infrastructure (Terraform)

All AWS resources are provisioned using Terraform.

Create Infrastructure

cd infra
terraform init
terraform plan
terraform apply

This creates:

• ECS cluster
• ECS task definition
• ECS service
• ECR repository
• CloudWatch log group
• IAM roles
• VPC + subnets

🐳 Container Build & Push (ECR)

aws ecr get-login-password --region us-east-1 \
 | docker login --username AWS --password-stdin <ACCOUNT_ID>.dkr.ecr.us-east-1.amazonaws.com

docker build -t pillsale-bot .
docker tag pillsale-bot:latest <ACCOUNT_ID>.dkr.ecr.us-east-1.amazonaws.com/pillsale-bot:latest
docker push <ACCOUNT_ID>.dkr.ecr.us-east-1.amazonaws.com/pillsale-bot:latest

Verifying the Bot Is Running Check ECS Service

aws ecs list-services --cluster infinite_loop-cluster

Check Running Tasks

aws ecs list-tasks \
  --cluster infinite_loop-cluster \
  --service-name app-test-service-g6kdm271

View Logs

aws logs tail /ecs/pillsale-bot --follow

If logs show polling and Telegram startup messages → ✅ bot is live.

How to Test

Open the bot on Telegram
Send /start
Send /notify

Wait for site status change (or simulate locally)

🔐 Environment Variables
TELEGRAM_BOT_TOKEN=xxxx
TARGET_URL=https://www.pillsale.fun/
MONITOR_TEXT=Coming Soon
CHECK_INTERVAL_MS=300000

Key DevOps Lessons Demonstrated

• ECS Fargate production deployment
• Terraform state & modular infra
• Container image lifecycle (build → push → deploy)
• CloudWatch log debugging
• IAM least-privilege roles
• Git hygiene (.terraform excluded)
