AWS Resource Tracker Shell Script

Project Overview

This project demonstrates how to automate AWS resource monitoring using a Bash shell script and AWS CLI.

The script retrieves information about commonly used AWS resources and displays them in the terminal. This helps reduce manual effort and provides a simple introduction to infrastructure automation using shell scripting.

Objectives

• Learn Bash Shell Scripting
• Use AWS CLI to interact with AWS services
• Automate repetitive AWS monitoring tasks
• Practice Linux command-line operations
• Build a beginner-friendly DevOps project

---

AWS Services Used

• Amazon S3
• Amazon EC2
• AWS Lambda
• AWS IAM

Script Used

#!/bin/bash

set -x

echo "Printing S3 Buckets"
aws s3 ls

echo "Printing EC2 Instances"
aws ec2 describe-instances

echo "Printing Lambda Functions"
aws lambda list-functions

echo "Printing IAM Users"
aws iam list-users

echo "Resource tracking completed successfully"

---

Prerequisites

Before running the script, ensure the following are installed and configured:

• Linux (Ubuntu)
• AWS CLI
• AWS Account
• IAM User with AWS CLI permissions
• Configured AWS Credentials

Verify AWS CLI installation:

aws --version

Verify AWS credentials:

aws sts get-caller-identity

How to Run the Project

Step 1: Create the Script

vim aws-resource-tracker.sh

Paste the script and save the file.

---

Step 2: Give Execute Permission

chmod +x aws-resource-tracker.sh

---

Step 3: Execute the Script

./aws-resource-tracker.sh

---

Sample Output

Printing S3 Buckets
bucket-1
bucket-2

Printing EC2 Instances
InstanceId: i-xxxxxxxxxxxxx

Printing Lambda Functions
FunctionName: demo-function

Printing IAM Users
UserName: admin

---

Cron Job Automation

Cron jobs can be used to schedule the script to run automatically at fixed intervals.

Open the cron editor:

crontab -e

Schedule the script to run every day at 6:00 PM:

0 18 * * * /home/ubuntu/aws-resource-tracker.sh

View existing cron jobs:

crontab -l

Check cron service status:

systemctl status cron
