Openshift (OKD) + Datasource Kubernetes issue

Hello,

We are running CheckMK Enterprise 1.6.0p7 and I’m trying to configure the Datasource Kubernetes for Openshift (OKD).

This is my setup:

  • CheckMK Enterprise 1.6.0p7
  • OpenShift Master: v3.11.0+bdd37ad-314
  • Kubernetes Master: v1.11.0+d4cacc0
  • OpenShift Web Console: v3.11.0+ea42280

I have followed the instructions precisely, verified all settings, and I believe everything is setup correctly. https://checkmk.com/cms_monitoring_kubernetes.html

I have tried debugging via command line. However, I receive the following error.

OMD[system]:~$ ~/bin/python ~/share/check_mk/agents/special/agent_kubernetes --url-prefix https://console.system.com --infos PODS --debug --port 8443 --token <removed> console.system.com

Please advise, how do I fix this issue?
