AWS Resource Reporting Script

Overview

This project provides a Bash script that reports all AWS resources, including S3 buckets, EC2 instances, Lambda functions, and IAM users. The script is designed to run on an EC2 instance and create a daily report of these resources. It utilizes AWS CLI commands and is scheduled to run automatically using cron jobs.

Step-by-Step Instructions

1. Configure AWS CLI

Run the following command to configure your AWS CLI with your access key and secret access key:

aws configure

• Enter your AWS Access Key ID.
• Enter your AWS Secret Access Key.
• Specify the default region name (e.g., us-east-1).
• Specify the default output format (e.g., json).

2. Create the Reporting Script

Create a new script file named project.sh and add the following content:

vim project.sh

Insert the following script into project.sh:

#!/bin/bash

# Author:- Sarvesh
# Date:- 7/09/2024
#
# This script will report all the AWS resources

set -x

# Lists S3 buckets
touch /home/ec2-user/daily_report
aws s3 ls >> daily_report

# List EC2 instances
aws ec2 describe-instances | jq '.Reservations[].Instances[] | {InstanceId: .InstanceId, InstanceType: .InstanceType}' >> daily_report

# List all Lambda Functions
aws lambda list-functions >> daily_report

# List all the IAM users
aws iam list-users >> daily_report

3. Install and Configure Cron

Execute the following commands to install and start the cron service:

sudo yum install cronie
sudo systemctl status crond
sudo systemctl start crond

4. Set Permissions for the Script

Make the project.sh script executable:

sudo chmod u+x project.sh

5. Schedule the Script with Cron

Open the crontab editor to schedule the script to run daily at 5:30 PM:

crontab -e

Add the following line to the crontab:

30 17 * * * /home/ec2-user/project.sh

6. Verify Cron Jobs

To verify that the cron job has been set up correctly, run:

cronie -l

Complete Summary

The AWS Resource Reporting Script is a comprehensive solution for monitoring and managing your AWS infrastructure. By executing this Bash script on an EC2 instance, users can automatically generate a daily report at 5:30 PM (17:30) that includes vital information about their AWS resources, such as:

• S3 Buckets: A list of all S3 buckets in the account.
• EC2 Instances: Details of EC2 instances, including their IDs and types.
• Lambda Functions: A list of all deployed Lambda functions.
• IAM Users: Information about all IAM users in the account.

The generated report is saved in a file named daily_report located in the /home/ec2-user/ directory. This automated reporting process helps users keep track of their AWS resources, enabling them to:

• Audit resource usage effectively.
• Identify unused or idle resources for cost optimization.
• Track changes in the AWS environment over time.
• Generate reports for compliance or billing purposes.

By scheduling the script to run daily at 5:30 PM using cron jobs, users can ensure that they always have up-to-date information about their AWS resources without manual intervention. This project is an essential tool for AWS administrators and developers looking to maintain visibility and control over their cloud infrastructure.
