Troubleshooting Kubernetes Upgrade Issues

kube-state-metrics (KSM) is not Discoverable

Cause

When you use the command-line interface (CLI) to upgrade the Kubernetes cluster from 4.0.0 to 5.0.0 or later, kube-state-metrics (KSM) is not discoverable because the KSM image URL has an extra registry name appended.

Resolution

You need to add the following parameters to the lmc-configuration.yaml file:

kube-state-metrics:
  enabled: true
  image:
    registry: registry.k8s.io
    repository: kube-state-metrics/kube-state-metrics
    tag: v2.10.0

Helm Upgrade is Failing

Cause

When you use the command-line interface (CLI) to upgrade the Kubernetes cluster from 4.3.0 or lower to 4.4.0 or later, the helm upgrade fails due to missing subcharts data for LM OTEL(OpenTelemetry) and LM-Logs in LM Container helm charts. 

Resolution

You need to add the following parameters to the lmc-configuration file:

lmotel:
  enabled: false
lm-logs:
  enabled: false
