helm template get first element and value

helm_template_first_element.md

I had this YAML list and I needed to extract the name of the first server without the port:

global:
  datastores:
     db:
       hosts:
       - name: prod-mongo-11
         port: 27017
       - name: prod-mongo-12
         port: 27017
       - name: prod-mongo-13
         port: 27017

Solution:

'{{ index .Values.global.datastores.db.hosts 0 "name"  }}'
