title: How can I set the prometheus.enabled flag to true in VMWare's Kubernetes FluentD Operator using the helm chart?
body: <p>I currently have a Kubernetes FluentD operator<a href="https://github.com/vmware/kube-fluentd-operator" rel="nofollow noreferrer">[1]</a> running in my environment. It deploys fine using the helm chart but I need to somehow set the <code>prometheus-enabled</code> flag when deploying the helm chart.</p>
  <p>The documentation states the following :</p>
  <pre><code>usage: config-reloader [&lt;flags&gt;]
  
  Regenerates Fluentd configs based Kubernetes namespace annotations against templates, reloading
  Fluentd if necessary
  
  Flags:
    ...
    --prometheus-enabled          Prometheus metrics enabled (default: false)
  </code></pre>
  <p>My question is, can I set this flag when I run the helm chart? ie.</p>
  <p><code>helm upgrade --install kfo &lt;prometheus-enabled=true&gt; \$CHART_URL --namespace \$INSTALL_NAMESPACE -f kfo/config.yaml</code></p>
  <p>where <code>config.yaml</code> consists of :</p>
  <pre><code>---
  meta:
    key: metadata
    values:
      region: ${AWS_REGION}
      env: ${ENV}
      cluster: ${KUBERNETES_CLUSTER_TYPE}
  rbac:
    create: true
  image:
    repository: vmware/kube-fluentd-operator
    tag: v1.12.0
  fluentd:
    extraVolumeMounts:
      - name: fluentd-template-mapping
        mountPath: /templates
  extraVolumes:
    - name: fluentd-template-mapping
      configMap:
        defaultMode: 420
        name: fluentd-template-mapping
  </code></pre>
  <p>If not, what can I do to set it?</p>
  <p>Thanks</p>
