A few years ago, I wrote about the vSphere with Tanzu enablement workflow. With the introduction of VCF 9, the underlying architecture and the enablement workflow UI has undergone significant improvements. So here’s an attempt at documenting the new supervisor workflow as well. Pro-Tip Enabling Supervisor Workflow is a pre-requisite to put your VCF-Automation to…
In this article, we will perform a backup of the TKGi cluster with Velero and then delete a namespace. We will then use the backup to restore the cluster to its original state. Below screenshot is a recap of what’s deployed in the cluster. Below screenshot confirms that the S3 bucket (velero-test) is empty. We…
In the previous articles, we have completed all the pre-requisites needed to proceed with Velero installation. We will now use the Velero CLI to execute the following code to complete the installation. The installation should now begin. Now that velero is installed, we can proceed to backup the TKGi Cluster. But we are done yet,…
In this blog we will look at the other pre-requisites and pre-configured information required for the installation apart from the one’s we did earlier in this series here and here. Install Velero CLI Step 1 – Install the binary Extract the tar bundle and install Velero CLI which we will use later to deploy Velero….
We will be using a TKGi cluster to setup Velero and to replicate a production environment, we will use the air-gapped (using images from private registry instead of pulling images directly from the internet) approach to install velero. Hence, we assume a private registry (ex: Harbor) and docker client already exists in the environment and…
Velero is an open-source tool that allows you to backup and restore your kubernetes cluster resources. In this series of blogs, we will look at the procedure of installing Velero in an air-gapped TKGi environment including the pre-requisites. Velero uses an object storage backend to store backup data and associated artifacts. MinIO is an open-source…
In my previous article, I described the process of enabling the Cloud Consumption Interface or CCI which enables you to deploy TKG workloads to a Supervisor Cluster via UI. Here, I will walk through the steps involved in using the UI to provision a cluster using the default and custom configuration. Provisioning a cluster through…
vCenter 8.0U3 was made generally available alongside VCF 5.2 on 25th June. While there are a lot of enhancements across the suite of products, I would like to describe about one such supervisor cluster related feature in this blog. Starting 8.0U3, what used to be known as vSphere with Tanzu, will now be termed as…
Recently, I came across a customer scenario where a storage refresh had to be performed in a TKGi environment, which meant migrating all existing infrastructure including the Persistent Volumes to new data stores. I intend to cover the steps involved in this migration on a very high level, while the focus being Persistent Volumes migration….
I was recently tasked with upgrading a Tanzu Kubernetes Cluster to v1.26.5 (version v1.26.5+vmware.2-fips.1 to be specific). Once I completed the upgrade, to my surprise, when I did a “kubectl get pods“, I found them to be missing. When i went digging for any known issues, I noticed something related to Pod Security that I…
