          This is not a bug. Job was executing on the master itself. The following step executed to resolve the issue. 

          To completely disable jobs from executing on the master and to solely utilize slave, the executors count on the master needs to be set to 0. This value is set on the Jenkins system configuration page which can be accessed by selecting Manage Jenkins on the lefthand size of the master landing page and selecting Configure System. Next to # of executors, enter 0 and then hit Save to apply the changes.

          So, what if I'm executing Jenkins with no slave nodes at all? I'm using Jenkins on a Pod.

          I would not be able to use Jenkins to deploy on Kubernetes? 

          Is that the policy?
