[Terraform] 테라폼 프로바이더(Provider) 및 VPC 생성

테라폼 프로바이더 생성

terraform 디렉터리 생성

$ mkdir terraform

$ cd $_

프로바이더 생성

$ vim provider.tf

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "3.25.0"
    }
  }
}

provider "aws" {
  # Configuration options
  shared_credentials_file = "~/.aws/credentials"
  region  = "us-east-1"
  profile = "tfa"
}

VPC 생성

$ vim vpc_vpc99.tf

resource "aws_vpc" "vpc99" {
    cidr_block = "10.99.0.0/16"
    tags = {
        Name = "vpc99"
    }
}

terraform init

$ terraform init

Initializing the backend...

Initializing provider plugins...
- Reusing previous version of hashicorp/aws from the dependency lock file
- Installing hashicorp/aws v3.25.0...
- Installed hashicorp/aws v3.25.0 (signed by HashiCorp)

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

terraform plan

$ terraform plan

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # aws_vpc.vpc99 will be created
  + resource "aws_vpc" "vpc99" {
      + arn                              = (known after apply)
      + assign_generated_ipv6_cidr_block = false

          + "Name" = "vpc99"
        }
    }

Plan: 1 to add, 0 to change, 0 to destroy.

------------------------------------------------------------------------

Note: You didn't specify an "-out" parameter to save this plan, so Terraform
can't guarantee that exactly these actions will be performed if
"terraform apply" is subsequently run.
