Vpc

The Vpc component lets you add a VPC to your app. It uses Amazon VPC. This is useful for services like RDS and Fargate that need to be hosted inside a VPC.

This creates a VPC with 2 Availability Zones by default. It also creates the following resources:

1. A security group.
2. A public subnet in each AZ.
3. A private subnet in each AZ.
4. An Internet Gateway, all the traffic from the public subnets are routed through it.
5. A NAT Gateway in each AZ. All the traffic from the private subnets are routed to the NAT Gateway in the same AZ.

Note

By default, this creates two NAT Gateways, one in each AZ. And it roughly costs $33 per NAT Gateway per month.

NAT Gateways are billed per hour and per gigabyte of data processed. By default, this creates a NAT Gateway in each AZ. And this would be roughly $33 per NAT Gateway per month. Make sure to review the pricing.

Create a VPC

sst.config.ts

new sst.aws.Vpc("MyVPC");

Create it with 3 Availability Zones

sst.config.ts

new sst.aws.Vpc("MyVPC", {
  az: 3,
});

Constructor

new Vpc(name, args?, opts?)

Parameters

• name string

• args? VpcArgs

• opts? ComponentResourceOptions

VpcArgs

az?

Type Input<number>

Default 2

Number of Availability Zones or AZs for the VPC. By default, it creates a VPC with 2 AZs since services like RDS and Fargate need at least 2 AZs.

{
  az: 3
}

Properties

id

Type Output<string>

The VPC ID.

nodes

Type Object

• elasticIps

• internetGateway

• natGateways

• privateRouteTables

• privateSubnets

• publicRouteTables

• publicSubnets

• securityGroup

• vpc

The underlying resources this component creates.

nodes.elasticIps

Type Output<Eip[]>

The Amazon EC2 Elastic IP.

nodes.internetGateway

Type InternetGateway

The Amazon EC2 Internet Gateway.

nodes.natGateways

Type Output<NatGateway[]>

The Amazon EC2 NAT Gateway.

nodes.privateRouteTables

Type Output<RouteTable[]>

The Amazon EC2 route table for the private subnet.

nodes.privateSubnets

Type Output<Subnet[]>

The Amazon EC2 private subnet.

nodes.publicRouteTables

Type Output<RouteTable[]>

The Amazon EC2 route table for the public subnet.

nodes.publicSubnets

Type Output<Subnet[]>

The Amazon EC2 public subnet.

nodes.securityGroup

Type SecurityGroup

The Amazon EC2 Security Group.

nodes.vpc

Type Vpc

The Amazon EC2 VPC.

privateSubnets

Type Output<Output<string>[]>

A list of private subnet IDs in the VPC.

publicSubnets

Type Output<Output<string>[]>

A list of public subnet IDs in the VPC.

securityGroups

Type Output<string>[]

A list of VPC security group IDs.

Methods

static get

Vpc.get(name, vpcID)

Parameters

• name string

  The name of the component.

• vpcID Input<string>

  The id of the VPC.

Returns Vpc

Reference an existing VPC instance with the given VPC ID. This is useful when you created a VPC in one stage and you want to reference it in another stage.

Imagine you created a VPC in the dev stage. And in your perosonal stage, ie. frank, instead of creating a new VPC, you want to reuse the same VPC from dev.

sst.config.ts

const vpc = $app.stage === "frank"
  ? sst.aws.Vpc.get("MyVPC", "vpc-0be8fa4de860618bb")
  : new sst.aws.Vpc("MyVPC");

Here vpc-0be8fa4de860618bb is the ID of the VPC created in the dev stage.
