Overview
The Operator decouples the deployment of Prometheus instances from the configuration of which targets they are monitoring. The Operator defines two custom resources: Prometheus and ServiceMonitor.
Custom Resources
Prometheus Resource
The Prometheus resource declares a "serviceMonitorSelector":
apiVersion: monitoring.coreos.com/v1
kind: Prometheus
...
spec:
serviceMonitorSelector:
matchLabels:
release: prometheus
ServiceMonitor Resource
A ServiceMonitor is a custom resource
The labels are important, they must match Prometheus serviceMonitorSelector.
The current service monitor list can be obtained with:
kubectl -n <namespace> get servicemonitors
