Helm - toYaml indenting dictionary/map correctly - kubernetes-helm

Question

My values.yaml file:
podSelector:
app: myApp
app.kubernetes.io/instance: myApp
My templates/temp.yaml file
apiVersion: something/v1beta
kind: SomeResource
metadata:
name: someName
spec:
selection:
labels:
{{ .Values.podSelector | toYaml | indent 4 }}
helm template . gives me :-
apiVersion: something/v1beta
kind: SomeResource
metadata:
name: someName
spec:
selection:
labels:
app: myApp
app.kubernetes.io/instance: myApp #This is not indented
As you can see, the second key/value pair is not indented. How can I achieve correct indentation? The labels must all be indented the same way

Answer 1

In your output you want:
spec:
selector:
labels:
app: ...
#^^^^^
# there are exactly 6 spaces here
In your Helm chart, the {{ ... | indent ... }} line needs to start at the first column, and the indentation value needs to match the number of spaces.
spec:
selector:
labels:
{{ .Values.podSelector | toYaml | indent 6 }}
{{/* no spaces at the start of the line; indent 6, not 4 */}}
If you're using ... | toYaml | indent ..., the indent applies to every line of the YAML. If there are spaces before the {{ ... }}, these effectively indent only the first line extra, which will cause YAML parse errors.
