Terraform을 통해서 VPC를 생성해보도록 하겠습니다. VPC를 생성할 때는 aws_vpc 리소스를 사용하시면 되고, 필수적으로 필요한 설정은 cidr_block 입니다.
CIDR은 중요한 개념이므로 위키백과를 반드시 한 번 읽어보시는 것을 추천드립니다.
provider "aws" {
region = "ap-northeast-2"
}
resource "aws_vpc" "main" {
cidr_block = "10.0.0.0/16"
tags = {
Name = "terraform-101"
}
}
Terraform Plan 명령어를 통해 생성되는 리소스를 확인합니다.
$ terraform plan
Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.
------------------------------------------------------------------------
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.main will be created
+ resource "aws_vpc" "main" {
+ arn = (known after apply)
+ assign_generated_ipv6_cidr_block = false
+ cidr_block = "10.0.0.0/16"
+ default_network_acl_id = (known after apply)
+ default_route_table_id = (known after apply)
+ default_security_group_id = (known after apply)
+ dhcp_options_id = (known after apply)
+ enable_classiclink = (known after apply)
+ enable_classiclink_dns_support = (known after apply)
+ enable_dns_hostnames = (known after apply)
+ enable_dns_support = true
+ id = (known after apply)
+ instance_tenancy = "default"

+ main_route_table_id = (known after apply)
+ owner_id = (known after apply)
+ tags = {
+ "Name" = "terraform-101"
}
}
Plan: 1 to add, 0 to change, 0 to destroy.
