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.
