Kepler crashing on Kubernetes cluster (Openstack)

[carre140]

Hi all
I have deployed prometheus and kepler on clean kubernetes cluster like described here https://sustainable-computing.io/installation/kepler-helm/

All kepler pods are crashing in loop

Versions:

• Kubernetes: v1.31.4
• Openstack: huracan 3.12.16
• Linux Os: Rocky Linux 8.10 (Green Obsidian)
• prometheus: kube-prometheus-stack-70.7.0
• kepler: kepler-0.5.13

Pods logs:
