Kubernetes plugin to provide option to overwrite hostname in podtemplate

Issue Type:	Bug
Assignee:	Carlos Sanchez
Components:	kubernetes-plugin
Created:	2018-07-12 21:57
Environment:	Jenkins ver. 2.60.3 Kubernetes plugin - 1.8.4
Priority:	Major
Reporter:	NOOR MOHAMED NAINAMOHAMED

if hostname is a added to the specs, container shell couldn't locate the hostname. Since jenkins slave sets pod name as hostname. Keeping both same as same. Is there a way to overwrite only hostname within a podname. Kubernetes support it where podname and hostname can be different. usecase is to have different podname and hostname. Trying to keep hostname as consistent for a build activity trying to avoid rebuild as build records hostname information in its objects.

Detail of the podtemplate used
