Can you also add the following to the PR helm pacakge helm index and create it in repo/beta directory. Steps:

• cd helm/charts/portworx
• helm package . # there is . at the end
• mkdir -p helm/repo/beta
• mv helm/charts/portworx/portworx-2.13.3.tgz helm/repo/beta
• cd helm/repo/beta
• helm repo index . --url https://raw.githubusercontent.com/portworx/helm/<your_branch_name>/repo/stable Add the resultant files to the PR, that way we can consume this as a helm chart for testing.

Hi everyone, sorry to burst into this - I just wanted to encourage you to go ahead with this. I found this PR while I am in the process of using kustomize to achieve some core changes you already have build in here. These changes would definitely be much appreciated. Like I need to get rid of namespace creation ( which is easy ) but the namespace is hard coded e. g. in a batch job - which needs an ugly replacement procedure ... Anyway, this definitely makes it harder and more time consuming to implement a POC in my/our case. Please make this PR happen if you can :)
