  • MultiAZ mode for high availability (default: false)
  • RDS subnets (default: false)

Networks:

  • 10.0.0.0/28 - nat #1
  • 10.0.0.16/28 - nat #2
  • 10.0.0.32/27 - RDS

  • 10.0.1.0/24 - app #1
  • 10.0.2.0/24 - app #2

Usage

Minimal setup: VPC, NAT gw, w/o rds subnets, w/o multiAZ support

module "project_vpc" {
  source            = "github.com/jetbrains-infra/terraform-aws-vpc-with-private-subnets-and-nat"
  project           = "myproject" // required
}

All options with default values:

module "project_vpc" {
  source            = "github.com/jetbrains-infra/terraform-aws-vpc-with-private-subnets-and-nat"
  project           = "myproject" // required
  multi_az          = false
  rds               = false
  nat_mode          = "gateway" // or "instance"
  nat_instance_type = "t2.small"
}

Outputs

  • vpc_id
  • subnet_public_1
  • subnet_public_2 (empty if MultiAZ mode disabled)
  • subnet_private_1
  • subnet_private_2 (empty if MultiAZ mode disabled)
  • subnet_rds_1 (empty if RDS support disabled)
  • subnet_rds_2 (empty if RDS support disabled)
  • db_subnet_group (empty if RDS support disabled)
  • nat_gw_ip_1
  • nat_gw_ip_2 (empty if MultiAZ mode disabled)
  • nat_instance_ip_1
  • nat_instance_ip_2 (empty if MultiAZ mode disabled)
  • default_security_group
