If you’ve been following along my recent blog posts, you’ll have seen that I have been spending some time ramping up on NSX-T and Pivotal Container Services (PKS). My long term goal was to see how these two products integrate together and to figure out the various moving parts. As I was very unfamiliar with both products, I took a piece-meal approach to both. First, I tried to get some familiarity with NSX-T. You can find my previous posts on NSX-T here: Building a simple ESXi host overlay network with NSX-T First steps with NSX-T Edge – DHCP Server Next…
This week I attended KubeCon and CloudNativeCon 2018 in Copenhagen. I had two primary goals during this visit: (a) find out what was happening with storage in the world of Kubernetes (K8s), and (b) look at how people were doing day 2 operations, monitoring, logging, etc, as well as the challenges one might encounter running K8s in production. Let’s start with what is happening in storage. The first storage related session I went to was on Rook. This was a presentation by Jared Watts. According to Jared, the issues that Rook is trying to solve are to avoid vendor lock-in…
In my previous post, I showed how to deploy Pivotal Container Services (PKS) on a simplified flat network. In this post, I will highlight some of the issues one might encounter if you wish to deploy PKS on a more complex network topology. For example, you may have vCenter Server on a vSphere management network alongside the PKS management components (PKS CLI client, Pivotal Ops Manager). You may then want to have another “intermediate network” for the deployment of the BOSH and PKS VMs. And then finally, you may finally have another network on which the Kubernetes (K8s) VMs (master,…
This post will walk you through a simplified PKS (Pivotal Container Service) deployment in my lab. The reason why I say this is simplified is because all of the components will be deployed on a single flat network. PKS has a number of network dependencies. These include the bosh agents deployed on the Kubernetes (K8s) VMs being able to reach the BOSH Director, as well as the vCenter server. Let’s not get too deep into the components just yet – these will be explained over the course of the post. So rather than trying to set up routing between multiple…
I’ve recently begun to look at NSX-T. My long-term goal is to use it to enable me to build multiple Kubernetes clusters used PKS, the Pivotal Container Service. The hope is then to look at some cool storage related items with Kubernetes. But first things first. Kudos to both Sam McGeown and William Lam for their excellent blogs on NSX-T. However, I’m coming at this as a newbie, and I’m not using a nested environment, but rather a 4 nodes physical environment in my lab. And I am also not separating my cluster into management and production, but rather using…
Today VMware has another cloud launch update, and this one is significant for many reasons. Our underlying goals of VMware Cloud are many. From an infrastructure perspective, the goal is to provide operational consistency no matter where the application is running, whether this is from an automation, security or governance perspective. But one thing that is often overlooked is what this operational consistency means to the developer. The goal, I feel, is to make it as simple as possible for developers to create their apps and make it as simple as possible to consume services that they might need for…
Last week, I had the pleasure to attend our CTO Ambassadors conference, hosted by our Global Field CTO Chris Wolf. This was an excellent week, especially for someone like me who works directly for a single business unit at VMware. It gave me great insight into the activities going on in our other business units at VMware. One of the highlights for me was our “Serverless” night, where I finally got an opportunity to learn about Serverless, Functions As A Service (FaaS), AWS Lambda and all that other stuff that I kept hearing about, but did not quite fully understand.…
