vpc.tf

In the Virtual private cloud and subnets section, we explained that a VPC is the beginning of an AWS infrastructure. In the vpc.tf file, we define this:

resource "aws_vpc" "gitlabha" {    cidr_block = "10.0.0.0/16"      enable_dns_hostnames = true      enable_dns_support = true      tags{       Name = "VPC-${var.environment}"     } }

We assign the VPC a private network address that, again, can be divided into subnets:

cidr_block = "10.0.0.0/16"  

We want to enable DNS hostnames for this VPC:

enable_dns_hostnames = trueenable_dns_support = true 

We can use tags to give the VPC a name that fits with the environment we define:

tags{ Name = "VPC-${var.environment}" }

Now that we have a basic VPC, we can divide it into further networks and create more objects. ...
