Integrating Github Actions with vSphere and VMware Cloud on AWS

by // 2 Comments

I have always been a fan of event-driven automation, the idea where you can automatically trigger a workflow or an operation based on a specific event. In the consumer world, the most popular example is the If This, Then That (IFTTT) service, which I use on a regular basis to automate the sharing of new articles from virtuallyGhetto to different Social Media channels.

For the Enterprise, this is also not a new idea and many folks including myself have been doing this for years in vSphere using vCenter Server Alarms. In fact, one example I still reference on a regular basis is from 2012 where you automatically apply a set of vSphere Security Hardening configurations to a Virtual Machine when a new VM Create Event is published by vCenter.

There are countless more examples of this concept beyond VMware but the general idea is to be able to subscribe to specific events and then automatically do something when a given event occurs. When Github Actions (Beta) was announced last year, I was really interested as I think this could open the door for a ton of interesting possibilities, especially from a VMware perspective around Continuous Integration/Development (CI/CD). I quickly registered for the Beta but did not get access until the start of this year. If you want to know what Github Actions can do, check out some of these demos that have been built by various folks from the community. The really exciting thing about Github Actions is that you can literally execute any workflow as long as you can containerized your business logic within a Docker Container. This means, you can use any language or tool that you are familiar with and make this work with Github Actions, pretty powerful stuff!

It was only recently while working on a personal project, which I hope will make its way to VMworld, that I finally got a chance to dig into Github Actions. I noticed in many of the online Github Action examples, that it included ways to deploy applications and containers to a Public Cloud but there was nothing that I found related to VMware. I figured, this would be a good learning opopournity for myself and I could even learn how to build my own Actions which can be useful for others to use or extend further.

Creating a vSphere Content Library directly on Amazon S3

by // 4 Comments

A few years back I had blogged about creating your own 3rd Party vSphere Content Library enabling customers to take advantage of different types of storage backing than just vSphere Datastores. The primary requirement was that the content endpoint was accessible over HTTP(s), which meant that a number of solutions could be used from a simple web server like Nginx to an advanced distributed object store like Amazon S3 for example.

The workflow to create a 3rd Party vSphere Content Library on S3 is fairly straight forward, here is high level summary:

  1. Organize the content on a local system (desktop)
  2. Run a python script to index and generate the Content Library metadata
  3. Upload the Content Library to S3


A disadvantage of the above solution is that each time you need to update or remove content, the entire process would have to be repeated again, including re-uploading the changes. Not only was this time consuming from an operational standpoint but now you also needed to also keep a full copy of all the content locally which can be several hundred gigabytes, if not more.

This topic was recently brought back up again by Gilles Chekroun, an SE in our Networking and Security Business Unit who reached out to see if there was a solution to help his customer who was running into this challenge. Over the last couple of weeks, I had been working with both Gilles and Eric Cao (Content Library Engineer) on how we could enhance the existing Python script which indexes and generates the Content Library metadata to also support running directly on Amazon S3 bucket.

Automating VM Template management using Content Library in VMC

by // 11 Comments

Today, the vSphere Content Library only supports a single deployable VM type using the Open Virtualization Format (OVF) standard. Although customers are familiar with both OVF and OVA (archive of OVF and VMDKs), support for vCenter VM Template is still one of the most highly requested feature for Content Library. This should come as no surprise since many of our customers have built operational procedures and automation workflows for managing VM deployments over the years and simply switching to another format has a significant impact to their existing workflows.

UPDATE (10/18/18) - The VMTX feature is now available in vSphere 6.7 Update 1

I know the Content Library team has been heads down working on a number of enhancements to Content Library and it looks like one of these improvements has recently made its way out onto VMware Cloud on AWS (VMC) which I had just noticed while working in my SDDC.


In VMC, when you right click on a VM and select "Clone as Template to Library", there will be a new option to capture a VM as a VM Template (VMTX) within a Content Library!
