Add support for prometheus ServiceMonitor

[arlyon]

It would be nice to be able to be able to include a CRD for a prometheus service monitor with the chart.

Hello @arlyon,

as previously stated, up until know we declined feature requests like that. However, I'd like to acknowledge that we started some discussions around that topic, as we see that you, our community has a demand for it.

So for now, no real updates on it but please be aware, we're talking over it.

Since then you can use the additionalServiceMonitors feature in the Prometheus-Operator. That's what we are using right now.

prometheus:
  additionalServiceMonitors:
    - name: traefik
      selector:
        matchLabels:
      ...

It would be nice because the old stable/traefik Helm Chart had this option. Might I create a PR?

@SantoDE are there any news since April on the discussions? I would also like to have a possibility to setup a ServiceMonitor or PodMonitor and maybe a PrometheusRule from this chart, as many here do. This is a common pattern.

@k3daevin you probably don't need to ask to create a PR and just create a PR :stuck_out_tongue:

[cubic3d]

@bclermont We already have two of them rejected ;)

+1 for PodMonitor

[cwrau]

Is there an update for this?

If you're not opposed to the idea anymore, maybe you can merge one of the existing PRs? Like #133?

Moving from nginx-ingress to Traefik and I'm really surprised this is not available out of the box.

Any chance this will be included soon? I see there were some PR that have added service monitors, but on master AFAIK it is not available anymore
