Terraform module to setup AWS VPC with required parameters. Based on Hashicorp's VPC module.
These types of resources are supported:
- VPC
- Subnet
- Route
- Route table
- Internet Gateway
- NAT Gateway
- VPN Gateway
- VPC Endpoint:
- Gateway: S3, DynamoDB
- Interface: EC2, SSM, EC2 Messages, SSM Messages, ECR API, ECR DKR, API Gateway
- RDS DB Subnet Group
- ElastiCache Subnet Group
- Redshift Subnet Group
- DHCP Options Set
- Default VPC
module "core" {
source = "github.com/lean-delivery/tf-module-awscore"
project = "Project"
environment = "dev"
availability_zones = ["us-east-1a", "us-east-1b", "us-east-1c"]
vpc_cidr = "10.0.0.0/16"
private_subnets = ["10.11.0.0/24", "10.11.1.0/24", "10.11.2.0/24"]
public_subnets = ["10.11.3.0/24", "10.11.4.0/24", "10.11.5.0/24"]
enable_nat_gateway = "true"
}
Sometimes you need to have a way to create VPC resources conditionally but Terraform does not allow to use count inside module block, so the solution is to specify argument create_vpc.
# This VPC will not be created
module "core" {
source = "github.com/lean-delivery/tf-module-awscore"
create_vpc = false
# ... omitted
}
