TKGI CLI

This topic describes how to use the VMware Tanzu Kubernetes Grid Integrated Edition Command Line Interface (TKGI CLI) to interact with the TKGI API.

Overview

The TKGI CLI is a command-line tool to manage Tanzu Kubernetes Grid Integrated Edition provisioned Kubernetes clusters. Use the TKGI CLI to create, manage, and delete Kubernetes clusters.

To deploy workloads to a Kubernetes cluster, use kubectl, the Kubernetes CLI.

The TKGI CLI was previously named the PKS CLI, and both CLIs accept the same commands and arguments.

This version of Tanzu Kubernetes Grid Integrated Edition is compatible with both the TKGI and the PKS CLIs. Enterprise PKS v1.7 and earlier versions are compatible with only the PKS CLI.

If you are using the PKS CLI:

• When using the reference below, substitute pks where the commands below use tkgi.
• Please consider revising your command line scripts to use the tkgi CLI:
  • New commands have been added to the tkgi CLI.
  • The pks CLI may eventually be deprecated.

WARNING: Resize only TKGI clusters that have been upgraded to the current TKGI version.

VMware recommends that you avoid using the tkgi resize command to perform resizing operations. Instead, use the tkgi update-cluster command as follows:

tkgi update-cluster CLUSTER-NAME --num-nodes NUMBER-OF-WORKER-NODES

Where:

• CLUSTER-NAME is the name of your cluster.
• NUMBER-OF-WORKER-NODES is the number of worker nodes that you want to set for the cluster.

For more information on updating clusters, see tkgi update-cluster below.

Synopsis

This command is deprecated as of TKGI v1.12. Please use tkgi update-cluster instead.

Resize requires a cluster name, and the number of desired worker nodes. Users can scale up clusters to the plan defined maximum number of worker nodes, or scale down clusters to one node.
