Automating the Creation of AWS VPC and Subnets for VMware Cloud on AWS
Yesterday I wrote about how to deploy a Single Host SDDC through the VMware Cloud on AWS web console. I mentioned some pre-requisites that where required in order for the deployment to be successful. Part of those is to setup an AWS VPC up with networking in place so that the VMC components can be deployed. While it’s not too hard a task to perform through the AWS console, in the spirit of the work I’m doing around automation I have gotten this done via a Terraform plan.
The max lifetime for a Single Instance deployment is 30 days from creation, but the reality is most people will/should be using this to test the waters and may only want to spin the SDDC up for a couple of hours a day, run some tests and then destroy it. That obviously has it’s disadvantages as well. The main one being that you have to start from scratch every time. Given the nature of the VMworld session around the automation and orchestration of Veeam and VMC, starting from scratch is not an issue however it was desirable to look for efficiencies during the re-deployment.
For those looking to save time and automate parts of the deployment beyond the AWS VPC, there are a number of PowerShell code example and modules available that along with the Terraform plan, reduce the time to get a new SDDC firing.
I’m using a combination of the above scripts to deploy a new SDDC once the AWS VPC has been created. The first one actually deploys the SDDC through PowerShell while the second one is a module that allows some interactivity via commandlets to do things such as export and import Firewall rules.
Using Terraform to Create AWS VPC for VMware Cloud on AWS:
The Terraform plan linked here on GitHub does a couple of things:
- Creates a new VPC
- Creates a VPC Network
- Creates three VPC subnets across different Availability Zones
- Associates the three VPN subnets to the main route table
- Creates desired security group rules
[Note] Even for the Single Instance Node SDDC it will take about 120 minutes to deploy…so that needs to be factored in in terms of the window to work on the instance.
