Provide a name (it must be DNS-compliant), select network (only networks defined during depoyment as workload networks are available here), add description and…

TKG Supervisor cluster is deployed as part of vSphere with Tanzu which provides ability to deploy TKG workload clusters (also known as guest clusters in the past) as well as vSphere Pods within a vSphere Cluster. All together with ordinary VMs in the same cluster. The main difference between the TKG with Management cluster (also known as standalone TKG) is that with vSphere with Tanzu we define additional object that can provide resource isolation for workload clusters (and/or vSphere Pods)….

How to – Connect to TKG node via SSH

How to – Connect to TKG node via SSH

Comments 0 Comment

As part of TKG we can distinguish two implementations – TKG with Management cluster also known as TKGm (multicloud) or TKG standalone. Eventhough nowadays these solutions are extremely close to each other especially if we deploy Supervisor cluster based on VDS, there are two different ways to access a TKG node via SSH. Why would you even need to do that? Mostly for troubleshooting, perhaps checking logs or kubelet status on a node locally. So how do we connect there?…

Before we can start the deployment of TKG Management Cluster there are a few prerequisities that needs to ba handled around two main topics: Bootstrap Machine Bootstrap Machine is required to initially host Cluster API that will take care of management cluster deployment. It could be a physical or a virtual machine, in my lab it’s obviously a VM. After bootstrapping the management cluster, the machine can be used to deploy and manage TKG workload clusters. Therefore, a set of…

Adding AKO repository to the Helm CLI fails

Adding AKO repository to the Helm CLI fails

Comments 0 Comment

Since some time you might experience a problem while adding AVI Kubernetes Operator (AKO) in your TKG/K8s cluster. While running following command: helm repo add ako https://projects.registry.vmware.com/chartrepo/ako you might get an error: saying ” https://projects.registry.vmware.com/chartrepo/ako cannot be reached. Error 404 page not found”. This is a VMware’s general issue with the repo itself and as I’ve heard there is some work in progress. However probably becasue of that OCI compliant charts have been uploaded to be used as a workaround or a…

It’s intended to be a step by step guide that will walk you through the entire process from the begining till the end. Starting from the vSphere, NSX and ALB infrastructure preparation up to a deployment of a sample…
