Terraform AWS

This document provides an overview of using Terraform to provision resources in AWS.

Prerequisites

Before getting started, make sure you have the following:

• An AWS account
• Terraform installed on your local machine
• AWS CLI configured with your AWS credentials

Getting Started

To begin using Terraform with AWS, follow these steps:

1. Clone the repository containing your Terraform configuration files.
2. Navigate to the directory where your Terraform files are located.
3. Run terraform init to initialize the working directory.
4. Create a new Terraform configuration file (e.g., main.tf) and define your AWS resources.
5. Run terraform plan to preview the changes that will be made or terraform show -json plan.out > plan.json to save the report to a json file.
6. Run terraform apply to apply the changes and provision the resources in AWS. You can also run terraform apply "plan.out" to using plan file ran before to save time.

Best Practices

When working with Terraform and AWS, consider the following best practices:

• Use version control to track changes to your Terraform configuration files.
• Separate your Terraform code into modules for reusability and maintainability.
• Use variables and input files to make your configuration more flexible.
• Use Terraform workspaces to manage multiple environments (e.g., dev, staging, production).
• Regularly review and update your Terraform code to reflect changes in your infrastructure.

Conclusion

Terraform provides a powerful and flexible way to provision and manage resources in AWS. By following best practices and leveraging the capabilities of Terraform, you can effectively automate your infrastructure deployment process.
