This page documents all output values that the VPC module exposes after creating the infrastructure.

​
VPC Outputs

​
vpc_id
string
The ID of the VPC.Example: vpc-0123456789abcdef0
​
vpc_cidr_block
string
The CIDR block of the VPC.Example: 10.0.0.0/16
​
default_security_group_id
string
The ID of the default security group created by AWS for the VPC.Example: sg-0123456789abcdef0
​
default_network_acl_id
string
The ID of the default network ACL created by AWS for the VPC.Example: acl-0123456789abcdef0

​
Subnet Outputs

​
public_subnets
list
List of IDs of public subnets.Example: ["subnet-abc123", "subnet-def456", "subnet-ghi789"]
​
private_subnets
list
List of IDs of private subnets.Example: ["subnet-abc123", "subnet-def456", "subnet-ghi789"]
​
database_subnets
list
List of IDs of database subnets.Example: ["subnet-abc123", "subnet-def456", "subnet-ghi789"]
​
elasticache_subnets
list
List of IDs of elasticache subnets.Example: ["subnet-abc123", "subnet-def456", "subnet-ghi789"]

​
Subnet Group Outputs

​
database_subnet_group
string
The name/ID of the RDS database subnet group. Only created if create_database_subnet_group is true and database_subnets are provided.Example: my-vpc-rds-subnet-group
​
elasticache_subnet_group
string
The name/ID of the ElastiCache subnet group. Only created if elasticache_subnets are provided.Example: my-vpc-elasticache-subnet-group

​
Route Table Outputs

​
public_route_table_ids

​
NAT Gateway Outputs

​
natgw_ids
list
List of NAT Gateway IDs. Only created if enable_nat_gateway is true. The number of NAT Gateways depends on the single_nat_gateway setting:

​
nat_eips_public_ips
list
List of public IP addresses of Elastic IPs for NAT Gateways. Only created if enable_nat_gateway is true.Example: ["54.123.45.67", "54.123.45.68", "54.123.45.69"]

​
VPC Endpoint Outputs

​
vpc_endpoint_s3_id
string
The ID of the VPC endpoint for S3. Only created if enable_s3_endpoint is true.Example: vpce-0123456789abcdef0
​
vpc_endpoint_dynamodb_id
string
The ID of the VPC endpoint for DynamoDB. Only created if enable_dynamodb_endpoint is true.Example: vpce-0123456789abcdef0

​
Usage Example

To reference these outputs in your Terraform configuration: 
module "vpc" {
  source = "github.com/Planview/tf_aws_vpc"
  
  name = "my-vpc"
  cidr = "10.0.0.0/16"
  
  azs             = ["us-east-1a", "us-east-1b", "us-east-1c"]
  private_subnets = ["10.0.1.0/24", "10.0.2.0/24", "10.0.3.0/24"]
  public_subnets  = ["10.0.101.0/24", "10.0.102.0/24", "10.0.103.0/24"]
  
  enable_nat_gateway = true
}

# Reference outputs
output "vpc_id" {
  value = module.vpc.vpc_id
}

output "private_subnet_ids" {
  value = module.vpc.private_subnets
}
