junior devops engineer new to Terraform here. how would I go about creating a Terraform config file that deploys a VPC and public subnet in us-west-1? thanks in advance
Here's an example Terraform code to create a VPC and public subnet in the us-west-1 region:

```
terraform {

  # NOTE: Replace with the version that you need or use
  required_version = ">= 1.2.0"

  required_providers {
    aws = {
      source = "hashicorp/aws"
      # NOTE: Replace with the version that you need or use
      version = "~> 4.16"
    }
  }
}

# Define the provider and region
provider "aws" {
  region = "us-west-1"
}

# Resources
resource "aws_vpc" "main" {
  cidr_block = "10.0.0.0/16"
}

resource "aws_subnet" "public" {
  vpc_id     = aws_vpc.main.id
  cidr_block = "10.0.1.0/24"
}
```

This Terraform config specifies the required versions for Terraform and the AWS provider. The specified region is us-west-1. It creates a VPC and public subnet and associates them both together.

I hope that helps! Let me know if you need help with anything else.
