I am setting up Dynamic Jenkins slaves provision in Kubernetes. The default jenkins/jnlp-slave:alpine works fine but I see this below error in Kubernetes Agent:
W0129 19:09:42.310410 26799 kuberuntime_container.go:191] Non-root verification doesn't support non-numeric user (jenkins)
The job is just to check the environment variables and it runs fine & gives a proper output. But why do we have this error message?
It seems an authentication problem. Take a look at these following:

Jenkins kubernetes plugin not working
Hope this helps.
