I want to dynamically inject multiple key value pairs in the helm chart using –set-string. This is the end goal I am trying to achieve:

apiVersion: v1
kind: ConfigMap
metadata:
  name: configmap1 
data:
  key1: "value1"
  key2: "Value2"

Where the following is dynamically injected:

  key1: "value1"
  key2: "value2"

So, if three key,value pairs are injected, it will render as:

  key1: "value1"
  key2: "value2"
  key3: "value3"

So far I have this in my template yaml file:

apiVersion: v1
kind: ConfigMap
metadata:
  name: configmap1
data:
  {{- range $env_key, $env_value := .Values.env }}
  {{ $env_key }}: "{{ $env_value }}"
  {{- end }}

This works well when it picks up the default values of env from values.yaml file:

env:
  key1: "value1"
  key2: "Value2"

This is how it looks like:

bash-3.2$ helm template my-helmchart
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: configmap1 
data:
  key1: "value1"
  key2: "Value2"
bash-3.2$ 

But I want to inject it using –set-string. This didn’t work:

bash-3.2$ helm template workflow-helmchart --set-string env={key1:value1,key2:value2}
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: configmap1 
data:
  0: "key1:value1"
  1: "key2:value2"
bash-3.2$ 

Any thoughts?
