A number of readers have hit me up with queries around how they can use the integrated Harbor image repository (that comes integrated with vSphere with Kubernetes) for applications that are deployed on their Tanzu Kubernetes Grid clusters, sometimes referred to as guest clusters. Unfortunately, there is no defined workflow on how to achieve this. The reason for this is that there are a number of additional life-cycle management considerations that we need to take into account before we can fully integrate these components. This includes adding new TKG nodes to the image registry as a TKG cluster is scaled.…
This short video will demonstrate how to deploy the embedded Harbor Image Registry in vSphere with Kubernetes. It will highlight the different PodVMs used for Harbor, as well as the Persistent Volumes required by some of the PodVMs. The demo will look at the integration between namespaces created in vSphere with Kubernetes and the Harbor projects. I will also show how to download the CA certificate to a client to enable remote access to Harbor. Finally, I will show how to tag and push some images up to the image registry.
Regular readers will know that I have been spending quite a considerable amount of time recently talking about VMware Cloud Foundation (VCF) 4.0 and vSphere with Kubernetes, formerly known as Project Pacific. Over the past month or so, we have seen how to deploy a VCF 4.0 Management Domain. We also looked at how to create a VCF 4.0 VI Workload Domain, at the same time deploying an NSX-T 3.0 Edge Cluster to the Workload Domain which is now automated in VCF 4.0. With this all configured, we then went through the steps of deploying vSphere with Kubernetes onto this…
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.…
