This short video will show you some of the initial steps that one might take once vSphere with Kubernetes has been successfully deployed via VMware Cloud Foundation (VCF) 4.0 and SDDC Manager. And FYI, as I know a number of reader have been asking this question, VCF 4.0 is now officially GA. In this short video, I will introduce you to the namespace concept in vSphere with Kubernetes as a way of allocating vSphere resources between multiple tenants. As well, we will see how to enable and use Harbor as a Container Image Registry. Finally we will deploy a StatefulSet…
Now that we have our vSphere with Kubernetes deployed, we take the next logical step in this post and deploy a Tanzu Kubernetes Grid (TKG) guest cluster. [Update] Whilst guest cluster isn’t an official name for the Tanzu Kubernetes cluster, I’ll use it in this post to differentiate it from the Supervisor cluster deployed with vSphere with Kubernetes. TKG is a full CNCF certified Kubernetes distribution. It is deployed as a set of virtual machines, in accordance with a TanzuKubernetesCluster manifest which we will look at later. The OS and K8s distribution is also specified in the manifest. There may…
In my previous post on VCF 4.0, we looked at the steps involved in deploying vSphere with Kubernetes in a Workload Domain (WLD). When we completed that step, we had rolled out the Supervisor Control Plane VMs, and installed the Spherelet components which allows our ESXi hosts to behave as Kubernetes worker nodes. Let’s now take a closer look at that configuration, and I will show you a few simple Kubernetes operations to get you started on the Supervisor Cluster in vSphere with Kubernetes. Disclaimer: “Like my earlier posts, I want to be clear, this post is based on a…
Another product added to the VMware portfolio with the acquisition of Heptio is Sonobuoy. In a nutshell, Sonobuoy will validate the state of your Kubernetes cluster by running a suite of non-destructive tests against your cluster. As part of the end-to-end (e2e) tests that are run by Sonobuoy, there is a also a subset of conformance tests run as well. These include things like best practices and interoperability tests. This will ensure that your Kubernetes cluster (whether is an upstream version or a third-party packaged version) supports all of the necessary Kubernetes APIs. You can read more about conformance here.…
After deploying and configuring the Harbor tile in Pivotal Ops Manager, I ran into a couple of issues with certificates. The first was encountered when I was trying to login to harbor from an Ubuntu VM where I was running all of my PKS and BOSH commands. It was also the VM where I pulled my container images, and the VM from which I now wanted to push them into Harbor. Harbor is our registry server for storing container images. Here is what I got on trying to login: cormac@pks-cli:~$ sudo docker login -u admin harbor.rainpole.com Password: Error response from…
In this post, I wanted to play a little more with our registry product (Harbor) and how it integrated with vSphere Integrated Containers (VIC). The workflow that I am going to show you in this post is using Docker on MAC to pull an image from the docker hub, do whatever I need to do with that image/application, and then push out the updated version to my private Harbor registry. From my Harbor registry I am then going to pull that image down and run it on my production VCH (Virtual Container Host). The VCH provides my docker API endpoint…
In my last post, I showed some of the new command line functionality associated with deploying out a new Virtual Container Host (VCH) with vSphere Integrated Containers (VIC). I also highlighted how VIC now includes both Admiral for container orchestration via templates and the harbor registry is used for storing docker images. Harbor hosts docker images and Admiral hosts templates. An Admiral template describes how docker images hosted on Harbor gets instantiated (Kudos again to Massimo for this explanation). In my last post, I showed how I finally managed to deploy my VCH. Now the idea was that I should…
