AWS Resource Listing Script

Description

This script automates the process of listing resources in an AWS account for a specified service and region using the AWS Command Line Interface (CLI). It simplifies the task of auditing and managing your AWS resources by providing a quick overview of the specified service's resources.

Supported AWS Services

The script supports the following AWS services:

1. EC2 - Elastic Compute Cloud instances.
2. RDS - Relational Database Service instances.
3. S3 - Simple Storage Service buckets.
4. CloudFront - Content Delivery Network distributions.
5. VPC - Virtual Private Cloud configurations.
6. IAM - Identity and Access Management users and roles.
7. Route53 - DNS and domain management.
8. CloudWatch - Monitoring and logging services.
9. CloudFormation - Infrastructure as Code stacks.
10. Lambda - Serverless function services.
11. SNS - Simple Notification Service topics.
12. SQS - Simple Queue Service queues.
13. DynamoDB - NoSQL database tables.
14. EBS - Elastic Block Store volumes.

Prerequisites

• AWS CLI: The AWS CLI must be installed and configured on your system.
• AWS Configuration: Ensure the AWS CLI is configured with appropriate credentials and default settings.

Installing AWS CLI

If you haven't installed the AWS CLI, you can do so by following these instructions:

# On macOS
brew install awscli

# On Linux
sudo apt-get update
sudo apt-get install awscli

# On Windows
Download the installer from the [AWS CLI installation page](https://aws.amazon.com/cli/).

Bash Script (AWS-Resource-List.sh)

Usage

1. Clone the repository or download the script.
2. Open your terminal and navigate to the directory containing the script.
3. Make the script executable (if it’s not already):

chmod +x aws_resource_listing.sh

4. Run the script with the desired service and region:

./aws_resource_listing.sh <service> <region>

Replace <service> with the desired AWS service (e.g., ec2, rds, etc.) and <region> with the AWS region (e.g., us-west-2, us-east-1, etc.).

Example

To list all EC2 instances in the us-west-2 region, you would run:

./aws_resource_listing.sh ec2 us-west-2

How It Works

The script leverages AWS CLI commands to query specific services based on the user inputs for service type and AWS region. Upon execution, the script will:

1. Check if the required AWS CLI is installed and configured.
2. Parse command-line arguments for the service and region.
3. Execute the appropriate AWS CLI command to list the resources for the specified service.
4. Output the results in a user-friendly format.

Python Script (AWS-Resource-List.py)

Usage

1. Clone the repository or download the script.
2. Ensure Python 3 is installed on your system.
3. Install any required Python dependencies, if any.
4. Run the Python script using the following command:

python aws_resource_list.py <aws_region> <aws_service>

Replace <aws_region> with the AWS region (e.g., us-west-2, us-east-1, etc.), and <aws_service> with the AWS service to query (e.g., ec2, rds, etc.).

Example

To list all EC2 instances in the us-west-2 region, you would run:

python aws_resource_list.py us-west-2 ec2

How It Works

The Python script works similarly to the Bash script but uses the subprocess module to interact with the AWS CLI. When executed, the Python script:

1. Verifies if the AWS CLI is installed and configured.
2. Takes command-line arguments for the service and region.
3. Executes the appropriate AWS CLI command using the subprocess module.
4. Prints the result of the AWS CLI command to the console in a user-friendly format.

Installation

To install the necessary tools for the Python script:

1. Install Python 3.x, if not already installed. You can download it from here.
2. Ensure the AWS CLI is installed and configured.

Notes

• Both Scripts Require AWS CLI: Ensure that the AWS CLI is installed and configured with appropriate access credentials before running the script.
• Service Name: When providing the service name, ensure it matches the supported services exactly as listed above (case-insensitive). For example, use ec2 for EC2 instances, s3 for S3 buckets, etc.

Troubleshooting

• AWS CLI Not Installed: If you receive an error indicating that AWS CLI is not installed, follow the installation instructions above.

• AWS CLI Not Configured: Ensure that you have set up your AWS credentials using aws configure. You can check the configuration by running:

  aws configure list
