How can I reference a helm array parameter with index

Question

I have this helm parameters in a values.yaml file.

spec:
   containers: 
     - name: mycontainer
       image: my.image.url

I would like to reference the name and image parameters from another kubernetes-resource.yaml file with index.

I tried

containerReference: {{ index .Values.spec.containers[0].name | quote }}

and

containerReference: {{ (index .Values.spec.containers 0).name | quote }}

But I get: bad character U+002D '-'

Can you give a little more complete example? What command are you running that produces that error? (There's almost no `-` in what you've shown.) — David Maze, Feb 07 '20 at 11:59
kubernetes-resource.yaml is a k8s resource yaml in templates directory. The values.yaml is the standard helm values.yam. The error is triggered with helm install — voutsasg, Feb 07 '20 at 12:05
Are you able to access other values? I am wondering because I think it should be `.Values` instead of `.Value`. — brass monkey, Feb 07 '20 at 12:25
