title: How to pass the content of a file to Helm values.yaml
body: <p>I want to use Helm chart of RabbitMQ to set up a cluster but when I try to pass the configuration files that we have at the moment to the values.yaml it doesn't work.</p>
  
  <p>The command that I use:</p>
  
  <pre><code>helm install --dry-run --debug stable/rabbitmq --name testrmq --namespace rmq -f rabbit-values.yaml
  </code></pre>
  
  <p>rabbit-values.yaml:</p>
  
  <pre><code>rabbitmq:
    plugins: "rabbitmq_management rabbitmq_federation rabbitmq_federation_management rabbitmq_shovel rabbitmq_shovel_management rabbitmq_mqtt rabbitmq_web_stomp rabbitmq_peer_discovery_k8s"
    advancedConfiguration: |-
      {{ .Files.Get "rabbitmq.config" | quote}}
  </code></pre>
  
  <p>And what I get for <code>advancedConfiguration</code>:</p>
  
  <pre><code>NAME:   testrmq
  REVISION: 1
  RELEASED: Thu Aug 29 10:09:26 2019
  CHART: rabbitmq-5.5.0
  USER-SUPPLIED VALUES:
  rabbitmq:
    advancedConfiguration: '{{ .Files.Get "rabbitmq.config" | quote}}'
    plugins: rabbitmq_management rabbitmq_federation rabbitmq_federation_management
      rabbitmq_shovel rabbitmq_shovel_management rabbitmq_mqtt rabbitmq_web_stomp rabbitmq_peer_discovery_k8s
  </code></pre>
  
  <p>I have to mention that:</p>
  
  <ul>
  <li>rabbitmq.config is an Erlang file</li>
  <li>I tried different things including indentation (<code>indent 4</code>)</li>
  </ul>
