I want to know if it's possible to use a value as an object key of a different value like this?
...
spec:
replicas: {{ .Values[.Release.Namespace].replicas }}
...When my values.yaml is like:
production:
replicas: 2
staging:
replicas: 1And I install like this:
helm install --namespace production my-release .If not, is there any other way to achieve this?
You can use more than one value file when installing a helm chart. You can have a "default" values.yaml, and then have several values.env.yaml files with the specific settings for each environment.
So you would have:
values.yaml
someConfigForAllEnvironments: truevalues.staging.yaml
replicas: 1values.production.yaml
replicas: 2template.yaml
...
spec:
replicas: {{ .Values.replicas }}
...And you would install with:
helm install --namespace production my-release -f values.production.yamlTake look at similar case: helm-values. You use the index template function, though its values layout is little bit different from yours; {{ index (index .Values .Release.Namespace) "replicas" }} should work.

You could iterate over the "namespaces" and use the one that matches the current namespace.
