VPC Peering via aws-cdk

Question

I created 2 VPCs using aws-cdk. cdk is creating route tables dynamically when cloudformation stack is created. I created a peering connection between the two VPCs I created using CfnVPCPeeringConnection but I am not sure how to add route to vpc peering connection as I do not know what would be the RouteTableId.

Answer 1

You probably mean the peering connection id. Once you know it you can modify the routing tables.

In typescript, you get it this way

import ec2 = require("@aws-cdk/aws-ec2");
....
const vpc_peering = new ec2.CfnVPCPeeringConnection (...)
const vpc_peering_id = vpc_peering.ref
