<p>Returns descriptive information about an Amazon VPC</p>
99
</div>
1010

11+
## Purpose
12+
13+
This module is considered to be a [data-only](https://www.terraform.io/docs/language/modules/develop/composition.html#data-only-modules) module. Given the name of a VPC and an optional set of availability zones, this module returns information about a VPC, such as public and private subnets, the VPC ID, etc. See the [outputs](outputs.tf) file for which data is returned from this module. This module is useful for workspaces that require such information without declaring repetitive `data` sources in your Terraform configurations.
14+
15+
## Usage
16+
17+
The following example creates a security group and an application load balancer.
18+
19+
```hcl
20+
provider "aws" {}
21+
22+
module "networking" {
23+
source = "github.com/mongodb-ansible-roles/terraform-aws-networking-readonly"
24+
version = "1.1.0"
25+
26+
vpc_name = "tutorial-vpc"
27+
}
28+
29+
resource "aws_security_group" "this" {
30+
ingress = [
31+
{
32+
cidr_blocks = ["0.0.0.0/0"]
33+
from_port = 443
34+
protocol = "TCP"
35+
to_port = 443
36+
}
37+
]
38+
39+
vpc_id = module.networking.vpc_id
40+
}
41+
42+
resource "aws_lb" "this" {
43+
internal = false
44+
load_balancer_type = "application"
45+
security_groups = [aws_security_group.this.id]
46+
subnets = module.networking.public_subnets
47+
}
48+
```
