## Action Required Before Upgrading

- If you are using Kubernetes to manage `docker` containers, please be aware Kubernetes has been validated to work with docker 1.9.1, docker 1.11.2 (#23397), and docker 1.12.0 (#28698)
- If you upgrade your apiserver to 1.4.x but leave your kubelets at 1.3.x, they will not report init container status, but init containers will work properly.  Upgrading kubelets to 1.4.x fixes this.

configuration to be stored as a Kubernetes API object and pulled dynamically on
container startup, as an alternative to baking in command-line flags when a
container is built.
