[GitBox <gi...@apache.org>]

mkoertgen opened a new issue #226:
URL: https://github.com/apache/pulsar-helm-chart/issues/226


   **Describe the bug**
   Dynamic labelmap-action in the current podMonitor-templates causes prom-operator skipping the PodMonitor altogether.
   
   **To Reproduce**
   Steps to reproduce the behavior:
   1. Install [kube-prometheus-stack>=32.2.0](https://github.com/prometheus-community/helm-charts/releases/tag/kube-prometheus-stack-32.2.0 or [prometheus-operator>=0.54](https://github.com/prometheus-operator/prometheus-operator/tree/v0.54.0)
   2. Install pulsar-helm-chart with `podMonitors` enabled, e.g. [zookeeper](https://github.com/apache/pulsar-helm-chart/blob/master/charts/pulsar/values.yaml#L304)
   3. See your metrics disappear
   4. See error in prometheus-operator-logs
