Setting up VS Code for terraform

• We need to install an extension for Terraform from hashicorp
  

Creating the required infra with Terraform

Activity 1: I want to create a vpc with 4 subnets in AWS

AWS Credentials

• Ensure you have aws cli installed and configured (view classroom recording to create one)

Data types in Terraform

• official docs
• string: this will be in quotes
• number
• bool
• list
• set
• map or object

Hashicorp Configuration Language (HCL)

• Refer Here for official docs

Terraform AWS Provider

• official docs
• Terraform block to choose the provider and version

terraform {
    required_providers {
        aws = {
            source = "hashicorp/aws"
            version = "5.82.2"
        }
    }

}

• Lets try to configure the provider

provider "<name>" {
    arg1 = value1
    ...
    ..
    argn = valuen

}

• AWS Provider Argument reference
• As of now our main.tf looks as shown below

terraform {
    required_providers {
      aws = {
        source = "hashicorp/aws"
        version = "5.82.2"
      }
    }
}

provider "aws" {
    region = "ap-south-1"
}

• Now from terminal
  • download providers and initialize terraform init
    
  • Format the template terraform fmt
  • Validate the template terraform validate
• Resource block in terraform

resource "type" "identifier" {
    arg1 = value1
    ...
    ..
    argn = valuen
}

• Now to find resources,
  • Search in provider docs
  • google terraform <cloud> <resource>
• vpc resource docs
• Add the vpc resource block so as of now the template is

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "5.82.2"
    }
  }
}

provider "aws" {
  region = "ap-south-1"
}


resource "aws_vpc" "network" {
  cidr_block = "10.10.0.0/16"
  tags = {
    Name = "from tf"
  }

}

• Now to create infrastructure, execute terraform apply where the plan will be shown
  
• To be continued…
