Getting kapp-controller to trust your CA certificates in TKG

Have you ever had to deploy a package using kapp-controller from your Harbor private registry?

I recently deployed the Tanzu RabbitMQ package to a TKGm workload cluster in an air-gapped/internet-restricted environment.

Doing so in air-gapped environments requires you to push the packages into Harbor, then have kapp-controller deploy the package from Harbor.

After adding the PackageRepository referencing my Harbor registry, I observed it couldn’t complete reconciling due to a certificate issue.

Since my previous posts on TAP Overview and Backstage, I have been diving deeper into TAP, trying to establish the practices around it.
