Talos OS vSphere Virtual Machine Terraform Module

Page in Terraform Registry

This module allows you to deploy a Talos OS-based vSphere virtual machine with a custom configuration. The configuration of the virtual machine fully corresponds to the configuration of Talos OS v1.0.x.

Usage

It is strongly not recommended to use this module separately, since creating groups of virtual machines does not make a full cycle of Terraform automation (you cannot continue working with the created cluster using Terraform). To create a cluster, use ilpozzd/vsphere-cluster/talos. This module is useful in some cases when using Terragrunt. See examples.
