Issue/Introduction

To resolve and complete the Tanzu CLI installation

Symptoms:
Installing Tanzu CLI on windows for TKG 1.5 following the below document.
https://docs.vmware.com/en/VMware-Tanzu-Kubernetes-Grid/1.5/vmware-tanzu-kubernetes-grid-15/GUID-install-cli.html

Windows Powershell throws a certificate error
 
> tanzu init
unable to list plugin from discovery 'default': error while processing package: failed to get resource files from discovery: Checking if image is bundle: Fetching image: Get "https://projects.registry.vmware.com/v2/": x509: certificate signed by unknown authority


Environment

Tanzu Kubernetes Grid 1.5.2

Cause

This appears to be the forcing of the incorrect Root CA

Resolution

Resolved in TKG v1.5.4

Workaround:
As a workaround, override the root CA certificate which is embedded in the CLI via the TKG_CUSTOM_IMAGE_REPOSITORY_CA_CERTIFICATE config variable i.e. if in PowerShell, use the following command before running `tanzu init` or `tanzu plugin`

Set the environment variable given below, this is just the base64 encoded version of the DigiCert Global Root CA PEM file, this can also be downloaded from
