title: Is it possible to set a hostname in a Kubernetes replication controller?
body: <p>I need to set a static hostname in a Kubernetes replication controller. Docker supports it with some runtime flags, however, Kubernetes replication controllers don't appear to support it.
  The environment: OS - CentOS 6.6
  Approach to use sysctl to change the variable kernel.hostname does not work for a K8s replication controller. The host name is not changed.
  Use:
  sysctl kernel.hostname
  to read the current hostname, and
  sysctl kernel.hostname=NEW_HOSTNAME</p>
  
  <p>Is it possible to set a hostname in a Kubernetes replication controller?</p>
