The new Tanzu portfolio has a plethora of new (and not so new) Kubernetes products that we are all getting used to. There are also some new names that we are using for existing VMware products. I decided to dedicate some time to figuring it all, and documenting it here for future posterity as I know others are also finding the new branding a challenge. Note that I’m not including the new suite of products that were added to the Tanzu portfolio when VMware acquired Pivotal. This post is focusing purely on the Kubernetes related products. Enterprise PKS is now…
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…
Another new feature added to the vSphere CSI driver in the vSphere 7.0 release is the ability to offline extend / grow a Kubernetes Persistent Volume (PV). This requires a special directive to be added to the StorageClass and, as per the title, the operation must be done offline whilst the PV is detached from any Pod. Let’s take a closer look at the steps involved. New CSI component – CSI Resizer To enable resizing operations, a new component has been added to the vSphere CSI Controller called csi-resizer. We can examine the csi-resizer and other components associated with the…
A common request we’ve had for the vSphere CSI (Container Storage Interface) driver is to support encryption of Kubernetes Persistent Volumes using the vSphere feature called VMcrypt. Although we’ve had VM encryption since vSphere 6.5, this was a feature that we could not support in the first version of the CSI driver that we shipped with vSphere 6.7U3. However, I’m pleased to announce that we can now support this feature with the new CSI driver shipping with vSphere 7.0. The reason we can support it in vSphere 7.0 is that First Class Disks, also known as Improved Virtual Disks, now…
With the release of vSphere 7.0, we also announced enhancements to our Cloud Native Storage (CNS) offering. One of the new features that we now offer in vSphere 7.0 is the ability to provision Virtual Volumes (vVols) to back Kubernetes Persistent Volumes (PVs) via our updated version of the vSphere Container Storage Interface (CSI) driver. In this post, I will walk through the steps involved in consuming vVols via Kubernetes manifest files when dynamically provisioning PVs. I will also show some enhancements to our CNS UI in vSphere 7.0 so that you can easily identify vVol backed PVs. Step 1…
This video will show the steps involved in deploying a fully functional Tanzu Kubernetes Grid cluster (TKG) via vSphere with Kubernetes. We will see how to build and sync a content library for the TKG control plane and worker node images. We will walk through the creation of a new namespace, and review the manifest file used for the creation of the cluster. Once deployed, we will switch contexts from the namespace used to build the cluster and place ourselves in the context of the new TKG cluster. From there, we will run some kubectl commands to query the cluster.…
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…
