Rancher and RKE on vSphere Terraform Script

This repo creates the following:

• 1x NGINX Loadbalancer
• 3x RKE Nodes leveraging Embedded HA, forming a K8s Cluster
• Installation of Cert-Manager and Rancher

Prerequisites

• Prior to running this script, a DNS record needs to be created to point at the Loadbalancer IP address, defined in the variable lb_address.

• The VM template used must have the Cloud-Init Datasource for VMware GuestInfo project installed, which facilitates pulling meta, user, and vendor data from VMware vSphere's GuestInfo interface. This can be achieved with:

curl -sSL https://raw.githubusercontent.com/vmware/cloud-init-vmware-guestinfo/master/install.sh | sh -

Or use the following Packer Template:
