Poem

A metric tweak, a subtle feat,
Where nils now count as zero neat.
Prometheus watches, ever wise,
With gauges clear before its eyes.
A rabbit hops, with metrics new—
Review is quick, the changes few!

88-91: Verify kube-state-metrics image tag ≥ v2.7.0

nilIsZero was added in the kube-state-metrics binary after v2.6. Because this chart doesn’t explicitly override the subchart’s image.tag, Helm will default to v{{ .Chart.AppVersion }} from the kube-state-metrics subchart. Please confirm that the pulled chart’s AppVersion (or your override) is at least v2.7.0:

• If you haven’t set kube-prometheus-stack.kube-state-metrics.image.tag in your top-level values.yaml, inspect the kube-prometheus-stack subchart’s AppVersion to ensure it’s ≥ 2.7.0.
• If the AppVersion is older, explicitly pin the image in values.yaml:

kube-prometheus-stack:
  kube-state-metrics:
    image:
      tag: v2.7.0
