diff does not honour "helm.sh/resource-policy: keep"

[timjohncurtis]

We have a deployment which used an older version of helm, which defines the namespace as a YAML object in the helm chart. We want to upgrade to removing this as is the defined method in helm 3, so have added helm.sh/resource-policy: keep as an annotation, however when I run helm diff on the chart, it shows it will be removed. This is intended functionality as the YAML no longer exists, but could a note be added to the output of the diff noting to the user that this is annotated so it will not be deleted?

I have the same problem.

I also just ran into this. I know it may be kind of an edge case, but it might be worth re-opening; even if just for visibility.

I have the same issue, in our case with secrets which are generated only if they do not already exist (check via lookup if one exists, if so use that, else generate a new one).
