How can a Virtual Private Cloud (VPC) be created using Infrastructure as Code (IaC) with Terraform?

Question

Accepted Answer

Create a VPC using Terraform by defining resources in a configuration file and applying it to your cloud provider.

Define the provider in your Terraform configuration (e.g., AWS, GCP). Example: `provider "aws" { region = "us-east-1" }`
Create a VPC resource using the `aws_vpc` resource block. Example: `resource "aws_vpc" "my_vpc" { cidr_block = "10.0.0.0/16" }`
Optionally, add subnets, route tables, and internet gateways to your VPC. Example: `resource "aws_subnet" "my_subnet" { vpc_id = aws_vpc.my_vpc.id cidr_block = "10.0.1.0/24" }`
Run `terraform init` to initialize the configuration and `terraform apply` to create the VPC and associated resources.
Use `terraform plan` to preview changes before applying them.
