Interesting Kubernetes application demos

by // 3 Comments

I am always on the lookout for cool and interesting demos to deploy, especially with some of the work I have been doing lately with vSphere with Kubernetes (K8s) and Tanzu Kubernetes Grid (TKG). I am sure many of you have probably seen the basic wordpress demos which seems to be the typical "Hello World" app for K8s and having something more compelling not only makes the demo more interesting but it can also help folks better understand how a modern applications can be built, deployed and run.

Below is a list of of the K8s demo applications that I have come across as part of my exploration and by no means is this an exhaustive list. I have been able to successfully deploy these applications running on the latest version of K8s (1.17 and 1.18) as I did come across other demos which did not work or I had issues setting up. If there are other K8s demos that folks have used, feel free to leave a comment and I will update the blog post after doing some basic testing.

For those of you who may not have a K8s environment and is running either vSphere 6.7 Update 3 or have access to a VMware Cloud on AWS SDDC, you can easily setup a TKG Cluster in under 30 minutes leveraging my TKG Demo Appliance Fling.

Big updates to the vCenter Event Broker Appliance (VEBA) Fling

by // 1 Comment

The vCenter Event Broker Appliance (VEBA) team has been working hard over the last couple of months on some pretty exciting enhancements and today we are pleased to announce the release of VEBA v0.3 which can be download from the VMware Fling site. Although this is a "dot" release, do not let that fool you as this release contains a large number updates including a major re-architecture in how events are consumed and processed at the core of VEBA.

While this re-architecture does introduce some breaking changes, it does unlock a number of new capabilities that our current users have been asking for. It also provides us with a solid foundation for delivering on future enhancements such as multi-vCenter Server support and additional event sources from NSX-T, vSAN and other VMware Cloud Services to just name a few. Today, the "V" in VEBA stands for vCenter, but in the future, I do see it changing to just "VMware" as it can support so many other solutions.

Having said that, some of the breaking changes also improves the overall user experience, especially as it relates to defining and consuming vCenter Server events as well as troubleshooting and debugging. The team is super excited to get this release in the hands of our community and we look forward to hearing your feedback!

What's New:

  • Introduction of the VMware Event Router which provides a modular and flexible architecture for decoupling the stream "Providers" such as vCenter Server from the actual stream "Processors" like OpenFaaS. More details including its architecture and design can be found here

ESXi on Intel NUC 10 (Frost Canyon)

by // 65 Comments

Just a heads up, if you are considering the latest 10th Generation of the Intel NUC (formally known as Frost Canyon) which are now available on Amazon, Newegg & SimplyNUC, there is an issue to be aware of. The onboard Intel NIC is not detected by ESXi which prevents the installer from proceeding. This issue was reported by a fellow reader named Ben who reached out to me over the holiday and with his help, I was able to get access to the system. It looks like the these NUCs have a newer version of I219-V NIC which is currently not recognized by either the vmklinux e1000 or ne1000 driver.

UPDATE (09/21/20) - The required ne1000 driver has been incorporated into ESXi 7.0 Update 1

UPDATE (08/21/20) - To disable the TPM 2.0 connection cannot be established message in ESXi, please see this blog post for more details.

UPDATE (01/20/20) - As shared on Twitter last Friday, we now have an updated ne1000 driver that will detect the Intel NIC found in the new 10th Gen NUC. You will need to replace the existing ne1000 driver with the new offline bundle, which can be downloaded from here. I would like to remind folks that the Intel NUC is not an officially supported platform from VMware and although have have enable this new system for the community, it does not mean this system or previous generations are supported.

There are two options to author a new ESXi Image Profile containing the ne1000 driver, the easiest method is if you have an existing vCenter Server and using the vSphere H5 Client and Image Builder UI. For more details, please take a look at this blog post for detailed instructions.
