My Jenkins Hosted In a Independent VM, I configured the Node-cloud Set-up with one of our Kubernetes Engine.

You can see on the screenshots, It is able to create the POD but unable to run the "jenkins-agent" file. (Its in the entrypoint of the image)

If you go inside the Pod do,  run the "jenkins-agent".It is connecting & working fine.

It is perfectly working with the default image "jenkins/inbound-agent4.3_4"

But it is not working with any of custom images.
