How to create a namespace if it doesn't exists from HELM templates


Kasun Siyambalapitiya <kasunsi@...>
 

Hi all,

I have a `kind: Namespace` template yaml like follows,

    apiVersion: v1
    kind: Namespace
    metadata:
      name: {{ .Values.namespace }}
      namespace: ""


How do I make `helm install` create the above-given namespace (`{{ .Values.namespace }}`) if and only if above namespace (`{{ .Values.namespace }}`) doesn't exits in the pointed kubernets cluster?

Thanks,
Kasun Siyambalapitiya

With an operator and a CRD?
