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 install the TKGI CLI, see Installing the TKGI CLI.
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
pkswhere the commands below usetkgi. - Consider revising your command line scripts to use the
tkgiCLI:- New commands have been added to the
tkgiCLI. - The
pksCLI might eventually be deprecated.
- New commands have been added to the
