We are using helm of prometheus operator chart stable, see this link for the source

and we use our values.yaml which works OK, in the value.yaml we are configing prometheus (men cpu etc) and the alertmanger.

Now I need to add the prometheus alert manger config, but not sure how to provide it via the values.yaml (tried, it doesn’t work)

Any idea how to pass the config of the alert manager ?

This is the value.yaml

grafana:
  enabled: true
alertmanager:
  enabled: false
  alertmanagerSpec:
    replicas: 3

Now I need to provide in addition file which contain the alert manager rules

like the following:

file: alerts.yaml

apiVersion: monitoring.coreos.com/v1
kind: PrometheusRule
metadata:
  creationTimestamp: null
  labels:
    prometheus: prometheus
    role: alert-rules
  name: prometheus-prometheus-rules
  namespace: mon
spec:
  groups:
    - name: ./prometheus.rules
      rules:
        - alert: CRITICAL -  nodes Disk Pressure
          expr: 'kube_node_labels{label_workern_cloud_io_group=“ds"} * on(node)kube_node_status_condition{condition="DiskPressure", status="true"} == 1'
          for: 5m
          labels:
            severity: CRITICAL

How should I pass also the alerts.yaml via the helm installation ?

helm install prom stable/prometheus-operator -n mon -f values.yaml

should I create my own chart and put it on template ? if so how it’s recommended for clean implementation ?
