title: Creating MongoDB through Helm with Gitlab fails
body: <p>I followed the instructions here to create a Mongo instance using <code>helm</code>. This requires some adaptation as it's being created through gitlab with gitlab-ci.
  Unfortunately, the part about <code>values.yaml</code> gets skimmed over and I haven't found complete examples for mongo through helm. [Many of the examples also seemed deprecated as well.]
  Being unsure how to address the issue, using this as a <code>values.yaml</code> file:</p>
  <pre><code>global:
    mongodb:
      DBName: 'example'
      mongodbUsername: &quot;user&quot;
      mongodbPassword: &quot;password&quot;
      mongodbDatabase: &quot;database&quot;
      mongodbrootPassword: &quot;password&quot;
      auth.rootPassword: &quot;password&quot; 
  </code></pre>
  <p>The following error is returned:</p>
  <pre><code>'auth.rootPassword' must not be empty, please add '--set auth.rootPassword=$MONGODB_ROOT_PASSWORD' to the command. To get the current value:
          export MONGODB_ROOT_PASSWORD=$(kubectl get secret --namespace angular-23641052-review-86-sh-mousur review-86-sh-mousur-mongodb -o jsonpath=&quot;{.data.mongodb-root-password}&quot; | base64 --decode)
  </code></pre>
  <p>Given that I'm only using <code>helm</code> as called by gitlab-ci, I am unsure on how to implement the <code>set</code> or otherwise set the root password.</p>
