Problem this snippet solves: How to create a VoltMesh node inside an existing VPC. The VoltMesh node will be a two interfaces node and so could be used as both an ingress or egress gateway for the VPC. How to use this snippet: Pre-Requirements: Get and create the following from the AWS console: Get the ID of the VPC in which you want to deploy the VoltMesh node Get the ID of the "workload subnet" where are sitting the ressources you want to expose with the VoltMesh node in the VPC Create and get the ID of the following: One subnet (/28 for instance) that will be used as "outside" subnet for the VoltMesh node ie handling the Internet connectivity One subnet (/28 for instance) that will be used as "inside" subnet for the VoltMesh node For more information regarding our AWS concepts, please refer to: https://www.volterra.io/docs/how-to/site-management/create-aws-site Have entered your AWS account credentials within the Volterra console.
