version kubectl's rolling-update command is compatible with Kubernetes 1.4 and higher only if you specify a new replication controller name. You will need to update to kubectl 1.4 or higher to use the rolling update command against a 1.4 cluster if you want to keep the original name, or you'll have to do two rolling updates.

If you do happen to use old version kubectl's rolling update against a 1.4 cluster, it will fail, usually with an error message that will direct you here. If you saw that...

  * `--admission-control=...,PodSecurityPolicy,...`
* Use authorization to limit users' ability to use specific PodSecurityPolicy objects

**What is the impact?**

A user that is authorized to create pods can make use of any existing PodSecurityPolicy, even ones they are not authorized to use.

**How can I mitigate this prior to installing 1.5.5?**

1. Export existing PodSecurityPolicy objects:
