Tanzu Kubernetes Grid (TKG) on vSphere 6.7 U3 - Part2

In this post, I will explain how to deploy and manage multiple Kubernetes workload clusters using TKG CLI.

To view the management cluster: tkg get management-cluster

To create a new workload cluster: tkg create cluster <cluster name> --plan=<cluster plan>

Now as per default dev plan one master, one worker, and a load balancer are deployed.

Tanzu Kubernetes Grid (TKG) on vSphere 6.7 U3 - Part1

TKG is an enterprise-ready Kubernetes runtime which provides a consistent, upstream-compatible implementation of Kubernetes, that is tested, signed, and supported by VMware. 

Installation

I am using a 3 node vSAN cluster running vSphere 6.7 U3 to deploy TKG. The first step is to prepare a VM that will be used to kickstart the deployment process. Here I am using a CentOS 7 VM with desktop UI. Download the TKG CLI, TKG Kubernetes OVA, and Load Balancer OVA from the following link:

https://my.vmware.com/en/web/vmware/downloads/info/slug/infrastructure_operations_management/vmware_tanzu_kubernetes_grid/1_x 

I am using the following versions:

• VMware Tanzu Kubernetes Grid CLI 1.1 Linux
• VMware Tanzu Kubernetes Grid 1.1.0 Kubernetes v1.18.2 OVA
• VMware Tanzu Kubernetes Grid 1.1 Load Balancer OVA

Unzip and install TKG CLI on the CentOS VM.

Kubernetes 101 - Part3 - Install kubectl on Windows

This article shows how to install kubectl on a Windows machine and connect to a remote Kubernetes cluster.

Open PowerShell as administrator and run the following:

Install-Script -Name install-kubectl -Scope CurrentUser -Force

This will download the installation files to Windows PowerShell script folder of the current user. In my case it is: C:\Users\vineetha\Documents\WindowsPowerShell\Scripts

Now browse to the above location in Powershell and execute the install-kubectl.ps1 file.

install-kubectl.ps1 [-DownloadLocation <path>]

Note: If you do not specify a DownloadLocation, kubectl will be installed in the user's temp directory.
