Terraform - Public subnet 및 Private subnet 생성

resource "aws_vpc" "main" {
  cidr_block       = "10.0.0.0/16"
  instance_tenancy = "default"

  tags = {
    Name = "main"
  }
}

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

  tags = {
    Name = "Main"
  }
}

 

- 가용 영역을 추가

 

- 인스턴스 생성 시 public ip를 할당 받도록 하겠다는 옵션이다.

 

provider "aws" {
  region = "ap-northeast-2"
}

resource "aws_vpc" "vpc-10-10-0-0" {
  cidr_block       = "10.10.0.0/16"
  instance_tenancy = "default"
  enable_dns_hostnames = true

  tags = {
    Name = "vpc-10-10-0-0"
  }
}

resource "aws_subnet" "sub-pub1-10-10-1-0" {
  vpc_id     = aws_vpc.vpc-10-10-0-0.id
  cidr_block = "10.10.1.0/24"
  availability_zone = "ap-northeast-2a"
  map_public_ip_on_launch = true
  
  tags = {
    Name = "sub-pub1-10-10-1-0"
  }
}

resource "aws_subnet" "sub-pub2-10-10-2-0" {
  vpc_id     = aws_vpc.vpc-10-10-0-0.id
  cidr_block = "10.10.2.0/24"
  availability_zone = "ap-northeast-2c"
  map_public_ip_on_launch = true
  # 이 부분 때문에 public ip가 부여 된다.
  
  tags = {
    Name = "sub-pub1-10-10-2-0"
  }
}

resource "aws_subnet" "sub-pri1-10-10-3-0" {
  vpc_id     = aws_vpc.vpc-10-10-0-0.id
  cidr_block = "10.10.3.0/24"
  availability_zone = "ap-northeast-2a"
  # pri이기 떄문에 pub과 다르게 이부분이 없다.
  
  tags = {
    Name = "sub-pub1-10-10-3-0"
  }
}

resource "aws_subnet" "sub-pri2-10-10-4-0" {
  vpc_id     = aws_vpc.vpc-10-10-0-0.id
  cidr_block = "10.10.4.0/24"
  availability_zone = "ap-northeast-2c"
  
  tags = {
    Name = "sub-pub1-10-10-4-0"
  }
}

- 위와 같이 코드를 작성하고 plan 후 apply하게 되면 vpc 및 subnet이 생성된다.
