Namespace isn't templated #178
Description
I had an error from ArgoCD which sent me searching for this functionality.
I found the previously raised issue (#80), but it was closed (along with the associated PR #78) purportedly because Helm handles this functionality via helm install ... --namespace ....
This doesn't apply, however, if you're doing something other than running helm install
For example, I need to install my helmify-generated chart as a sub-chart in its own namespace (meaning I can't just set the Argo app destination namespace, as this would apply to the parent chart, too). The error Argo gives (if this is useful):
InvalidSpecError: Namespace for parent-sub-app apps/v1, Kind=Deployment is missing.;InvalidSpecError: Namespace for parent-sub-app apps/v1, Kind=Deployment is missing.
I can temporarily workaround this using -preserve-ns, but I think the aforementioned PR should also be reconsidered.
