Automated VMware Cloud Foundation (VCF) host commission using ESXi Kickstart

by // 1 Comment

ESXi Scripted Installation (Kickstart) has been my go-to method for achieving zero-touch provisioning of ESXi hosts at scale, which I had started using back in the ESX 2.5 days when I was a customer! Having worked at some very larger enterprises, I got the opportunity to experience and manage a variety of environments for automated ESXi provisioning.

For more than a decade, I have written hundreds of articles about ESXi kickstart and how it can help solve a variety of use cases stemming from my own background to some of the unique requirements that have come up from some of our largest VMware customers. To date, some of my favorite ESXi kickstart solutions includes my 2014 blog post in automating VM deployments using a USB device which became the basis for my USB to SDDC project in 2017.

While playing with the latest VMware Cloud Foundation (VCF) 5.1 Holodeck release (currently in Beta), I was thinking about the current VCF host commissioning workflow, which is a multi-step process after an ESXi host has been provisioned where you need to manually (or using automation) to add the hosts to SDDC Manager before they can be consumed for either expanding and/or deploying a new workload domain.

I thought, why could we not just skip this step all together and that was when I had the idea of just incorporating the VCF host commissioning workflow automatically as part of an ESXi Kickstart installation! 😀

Determining new VMware vSphere Foundation (VVF) & VMware Cloud Foundation (VCF) license usage in vSphere 8.0 Update 2b

by // 14 Comments

vSphere 8.0 Update 2b was just released last week and with this release, customers can now take advantage of the new included 100 GiB trial vSAN storage capacity for each deployed VMware vSphere Foundation (VVF) core for use with vSAN!

Note: If you would like to understand how much vSAN storage you are entitled to (100GiB for VVF and 1TiB for VMware Cloud Foundation (VCF)), check out the new inventory and calculator script in KB 95927 (brownfield) and KB 96426 (greenfield) for more details.

In addition to installing and/or updating your vCenter Server to vSphere 8.0 Update 2b, you will also need to login to Customer Connect to download your new VVF and/or VCF license keys that will activate your vSAN entitlement.

I have already received questions on how to determine whether an ESXi host has been licensed with the new VVF and/or VCF license keys and which you can do so by using the vSphere UI by navigating to Administration->Licensing->Licenses->Assets->Hosts or vSAN Clusters and using the various filters, but this can be time consuming when you have a large environment with various license editions.

This is where automation and vSphere API can help!

Automated VMware Cloud Foundation (VCF) Workload Domain deployment using PowerVCF

by // 4 Comments

Using my Automated VMware Cloud Foundation (VCF) Lab Deployment script, you can quickly get to a functional VCF Management Domain which includes deploying the required Nested ESXi VMs and the Cloud Builder appliance, end-to-end automated deployment .


After recently enhancing the script to support the latest VCF 5.1 release and enabling users to also specify the Nested ESXi VMs that can be used to setup a VCF Workload Domain, I wanted to take it one step further and also automate the VCF Workload Domain deployment and utilizing the infrastructure that was setup in the initial deployment script.

Previously, if you wanted to create a Workload Domain, you would need to deploy the required Nested ESXi VMs, commission the ESXi hosts into SDDC Manager and then either use the Workload Domain creation wizard in SDDC Manager or manually construct the required JSON configuration file for an automated installation.
