Tips & Tricks for deploying VMware Cloud Foundation (VCF) using Holodeck

by // 4 Comments

The VMware Cloud Foundation (VCF) Holodeck Toolkit has become quite popular amongst our field teams for quickly spinning up a fully self-contained VCF environment, running on just a single physical ESXi host for educational and hands on experience.

Internally, we have a Holodeck Google Space which has been getting quite busy where folks can ask questions but also share their own experiences and setup using Holodeck. I had noticed there were some common questions and themes that were coming up along with some neat tips and tricks from various folks, some of which I also found quite insightful.

I know some of these tips and tricks will also benefit our customers and partners looking to deploy VCF using Holodeck, so I figure I put together a consolidated list that would benefit everyone. If you have other Holodeck tips and tricks, feel free to leave a comment and happy to keep updating this page.

Dynamically generate custom vSAN ESA HCL JSON for VMware Cloud Foundation (VCF) 5.1

by // 6 Comments

I recently shared on how you can deploy the latest VMware Cloud Foundation (VCF) 5.1 release with vSAN Express Storage Architecture (ESA) using Nested ESXi and leveraging a custom vSAN ESA HCL JSON file, which I had created to workaround the required vSAN ESA pre-check during the VCF Bringup process.

I will admit, I actually did not the create the custom vSAN ESA HCL JSON file manually, it was auto-generated using automation 😉

My initial goal was to make it easier for anyone to play with VCF 5.1 using both Nested ESXi as well any physical system that is capable but may is not on the official VMware vSAN ESA HCL. After a lot of trial and error testing with Nested ESXi, I finally had a functional PowerCLI script that can then be used to run against a standalone ESXi host to dynamically generate a compatible custom vSAN ESA HCL JSON file that can then be used with both VCF 5.1 with vSAN ESA or even a standalone vCenter Server deployment for vSAN ESA enablement.

How to setup private GitLab on a Synology for Project Keswick?

by // 3 Comments

My recent blog post on setting up a custom vSphere Content Library on my Synology gave me another idea that I had been thinking about regarding Project Keswick, which was announced back at VMware Explore Las Vegas.

If you have network connectivity to the Keswick Cloud Service, you can easily associate a Git repository, which is used for host configurations and workload deployments using GitOps using Github or even a privately managed Gitlab instance. For organizations that have additional compliance, security or air-gapped requirements, using the Keswick Cloud Service may not be an option. With that said, Project Keswick also supports an advanced deployment option where the association of a Git repository, such as GitLab, can also be accomplished without requiring the use of the Keswick Cloud Service.

While I have had experience using both Github as well as GitLab, which VMware uses to host its own code repository, I have actually never setup my own GitLab instance before. I thought this would be a great learning opportunity, especially with the ability to run additional add-on applications on a Synology.

After a bit of researching online, I found that GitLab can easily run as a Container workload and it just so happens that the Synology DiskStation Manager (DSM) has a package for running containers creatively called Container Manager and below are the step by step instructions for setting up GitLab running on Synology DSM 7.2.
