Getting started with VCF Part 10 – Kubernetes deployment

With Enterprise PKS deployed in a Workload Domain in VMware Cloud Foundation, we now come to the point where we can begin to create Kubernetes clusters and deploy some containerized applications. We need access to some tooling to achieve this. One option is to SSH onto the Operations Manager appliance, as it has many of the necessary tools already installed. However, I prefer to do this in my own management/jump desktop rather than use components that are part of the actual product. In this post, I will show you the steps to get setup with the required tool-set, deploy your…

Getting started with VCF Part 9 – PKS deployment

We are nearing the end of our journey with Getting Started with VMware Cloud Foundation (VCF). In this post, we will go through the deployment of Enterprise PKS v1.5 on a Workload Domain created in VCF v3.9. We’ve been through a number of steps to get to this point, all of which can be found here. Now we have some of the major prerequisites in place, notably NSX-T Edge networking and PKS Certificates, so we can proceed with the Enterprise PKS deployment. However, there are still a few additional prerequisites needed before we can start. Let’s review those first of…

NSX-T Edge T0 Router: Static Route + SNAT instead of BGP

If you been following my adventures of deploying Enterprise PKS 1.5 on VMware Cloud Foundation (VCF) 3.9, you will be aware that I spent a considerable amount of time establishing Border Gateway Protocol (BGP) peering between my NSX-T Edge T0 Logical Router and my physical Upstream Router as documented in this post. This allows them to exchange route information, so that when one of my internal overlay networks needs to communicate externally, it can do so. However, I am in the fortunate position where I can access my Upstream Router and make any necessary BGP configuration changes to allow it…

Getting started with VCF Part 7 – NSX-T Edge

I think now is a good time to take a recap on what we have built so far with VMware Cloud Foundation (VCF). We’ve done a number of activities to date, notably the deployment of the management domain in part 1. Then we spend some time deploying the vRealize Suite of products in parts 2, 3 and 4. In part 5, we commissioned some additional ESXi hosts and then most recently we created our first workload domain in part 6, which included the deployment of NSX-T 2.5. Now we come to quite a long section, which is the deployment of…

Kubernetes on vSphere 101 – Ingress

As I was researching content for the 101 series, I came across the concept of an Ingress. As I hadn’t come across it before, I wanted to do a little more research on what it actually did. It seems that in some ways, they achieve the same function as a Load Balancer in so far as they provide a mean of allowing external traffic into your cluster. But they are significantly different in how they do this. If we take the Load Balancer service type first, then for every service that is exposed via a Load Balancer, a unique external…

A first look at vRealize Network Insight for Kubernetes

Regular readers will know that I have been spending quite a bit of time recently looking at Kubernetes running on vSphere. I’ve written a number of posts on the storage side of things, which you can read here as part of my 101 series. I also posted about how you can setup vRealize Operations Manager 7.5 and add the Management Pack for Container Monitoring. This provide some really good dashboards for examining the state of your K8s clusters, as well as detailed breakdowns into K8s node VM health and performance (CPU, Memory, DIsk IO). Not only that, but you can…

Kubernetes on vSphere 101 – Services

This will be last article in the 101 series, as I think I have covered off most of the introductory storage related items at this point. One object that came up time and again during the series was services. While not specifically a storage item, it is a fundamental building block of Kubernetes applications. In the 101 series, we came across a “headless” service with the Cassandra StatefulSet demo. This was where service type ClusterIP was set to None. When we started to look at ReadWriteMany volumes, we used NFS to demonstrate these volumes in action. In the first NFS…
