From f7fca469de23b64b9ae797076721beff21e25848 Mon Sep 17 00:00:00 2001 From: Ruslan Aliev Date: Sun, 14 Mar 2021 22:39:09 -0500 Subject: [PATCH] Add KRM function to validate site documents Proposed KRM function can perform static validation of the site documents based on Kubeval. It allows to specify additional CRD locations to be able to validate custom resources. As input, it uses document bundle created from desired phase's document entry point or output from render command.
