Terraform Implementation

This project uses Terraform workspaces to manage multiple environments (Dev, Stg, Prod).

Project Structure

• main.tf - Main configuration file with resource definitions
• variables.tf - Input variables
• locals.tf - Local variables for environment configurations
• outputs.tf - Output values

Usage Instructions

1. Initialize Terraform:

   terraform init
   

2. Create and select a workspace:

   terraform workspace new dev
   terraform workspace new stg
   terraform workspace new prod
   terraform workspace select dev
   

3. Deploy resources:

   terraform plan
   terraform apply
   

4. To switch environments:

   terraform workspace select stg
   terraform apply
