TransitGatewayRouteTableAssociation

The TransitGatewayRouteTableAssociation resource allows you to associate a transit gateway route table with a specified transit gateway attachment in AWS. This association is essential for routing network traffic through the transit gateway. More information can be found in the AWS EC2 TransitGatewayRouteTableAssociations documentation.

Minimal Example

Create a basic Transit Gateway Route Table Association with required properties.

import AWS from "alchemy/aws/control";

const transitGatewayAssociation = await AWS.EC2.TransitGatewayRouteTableAssociation("tgRouteTableAssociation", {
  TransitGatewayRouteTableId: "tgw-rtb-0123456789abcdef0",
  TransitGatewayAttachmentId: "tgw-attach-0123456789abcdef0"
});

Advanced Configuration

Configure a Transit Gateway Route Table Association with the optional adopt property to enable adopting existing resources.

const transitGatewayAssociationWithAdopt = await AWS.EC2.TransitGatewayRouteTableAssociation("tgRouteTableAssociationWithAdopt", {
  TransitGatewayRouteTableId: "tgw-rtb-0123456789abcdef0",
  TransitGatewayAttachmentId: "tgw-attach-0123456789abcdef0",
  adopt: true // Enable adopting existing resource if it already exists
});

Detailing the Resource

Here’s how to create a Transit Gateway Route Table Association while checking for the existence of the resource before attempting to create it.

const conditionalTransitGatewayAssociation = await AWS.EC2.TransitGatewayRouteTableAssociation("conditionalTgAssociation", {
  TransitGatewayRouteTableId: "tgw-rtb-0123456789abcdef0",
  TransitGatewayAttachmentId: "tgw-attach-0123456789abcdef0",
  adopt: true // Adopt if it already exists
});

Leveraging the Resource ARN

When creating the Transit Gateway Route Table Association, you can access the ARN of the resource after creation.

const transitGatewayAssociationWithArn = await AWS.EC2.TransitGatewayRouteTableAssociation("tgAssociationWithArn", {
  TransitGatewayRouteTableId: "tgw-rtb-0123456789abcdef0",
  TransitGatewayAttachmentId: "tgw-attach-0123456789abcdef0"
});

// Access the ARN of the created resource
console.log(`Created Transit Gateway Route Table Association ARN: ${transitGatewayAssociationWithArn.Arn}`);
