start-stop-ec2/

This directory contains Terraform configurations for managing EC2 instances, including the provisioning of resources and setting up automation using AWS Lambda and EventBridge.

provisioning/

• common/: Contains common Terraform modules and configurations for managing EC2 instances.
• dev/: Environment-specific configurations, such as variables or overrides, for development environments.

start-stop-rds/

Similar to start-stop-ec2/, this directory contains Terraform configurations for managing RDS instances.

.gitignore

Specifies intentionally untracked files to ignore, such as local development environment settings or sensitive files.

README.md

You're currently reading it! This file provides an overview of the repository, its contents, and instructions on how to use the provided Terraform configurations.

Usage

1. Clone this repository to your local machine.
2. Navigate to the desired directory (start-stop-ec2/ or start-stop-rds/) containing the Terraform configurations.
3. Customize the configurations as needed, including variables, IAM roles, and event rules.
4. Run terraform init to initialize Terraform.
5. Run terraform plan to preview the changes Terraform will make.
6. Run terraform apply to apply the changes and provision resources in your AWS account.
7. Monitor the AWS Management Console or logs to verify the automation and ensure instances are started and stopped according to the defined schedules.

Notes

• Ensure you have the necessary permissions and IAM roles configured to execute Terraform operations and manage resources in AWS.
• Review and adjust the event schedules (cron expressions) in rule.tf to align with your desired start and stop times for instances.
• Update the variables.tf file with any additional configuration variables or settings required for your environment.
