You should be able to tweak this to work for you:
apiVersion: v1
kind: ConfigMap
metadata:
name: {{ .Release.Name }}-configmap
data:
config.json: |-
{
{{- range $key, $val := .Values.json }}
{{ $key | quote | indent 6}}: {{ $val | quote }}
{{- end}}
}
values.yaml
json:
key1: val1
key2: val2
key3: val3apiVersion: v1
kind: ConfigMap
metadata:
name: mangy-hare-configmap
data:
config.json: |-
{
"key1": "val1"
"key2": "val2"
"key3": "val3"
}
Or you can try loading the yaml using following way:
{{ (.Files.Glob "files/indexes.conf").AsConfig | indent 2 }}
