Secrets and extravolumes for fluentd-aggregator about helm-charts

[stevehipwell]

@PushRom I'd be happy to add extra volumes to the chart, it's actually already coded and just waiting for a chart minor release. I think all the secret mounts other than volume are present. I won't enable the creation of secrets through the chart, this isn't a good pattern as the secret values end up in the Helm state and lifecycling secrets with Helm doesn't make sense. I'd recommend always maintaining external secrets external to the chart.

Ok. Let's wait for the release

@PushRom even with the coming extraVolumeMounts I'd recommend binding your secrets to env as demonstrated below; you can then use them directly in your Fluentd config. The added benefit of this is that it works in the current chart version (I use it extensively).

env:
  - name: SECRET_USERNAME
    valueFrom:
        secretKeyRef:
          name: mysecret
          key: username
    - name: SECRET_PASSWORD
      valueFrom:
        secretKeyRef:
          name: mysecret
          key: password
