Define values for each namespace

values.yaml

replicas: {
  test: 1,
  stage: 2,
  prod: 3
}

Here I am trying to use Helm templates to define number of replicas per namespace but am unsure of the proper syntax and pattern:

deployment.yaml

replicas: {{ .Values.replicas.{{ .Release.Namespace }} }}

So if this were deployed to --namespace=prod, I would expect the template to return:

# .Values.replicas.prod
replicas: 3
Solution

  • All of the template functions provided by the standard Go text/template library are available. In particular, that includes an index function which can do dynamic lookup in an array or map object.

    replicas: {{ index .Values.replicas .Release.Namespace }}
