    Deploy vSphere VMs with Ansible!

    In a previous post, we covered how to create a virtual machine from a VM template in vSphere using Python and the REST API as an example of service-agnostic methods to invoke infrastructure resources. VMware's PowerCLI is a fantastic tool, but it's not for me. Tweaking or porting functionality from PowerCLI to other …
