Read and set values to template

to render kubernetes manifest files inside template folder either you send values via values.yaml or --set option through command line

assume you have below line in you manifest file of templates folder

image: {{ .Values.application.image}}

then your values.yaml should look like below

application:
  image: deekshithsn/node-ui

if you want to send any value from command line then use this command helm install example --set application.image="busybox"
