An alternative approach is modifying the existing CoreOS templates in-place. It might be a little difficult to implement but it saves your overhead to deprecate the old version and roll out the new version.<o:p></o:p></span></p>

<p class="MsoNormal">Hi,<br>
<br>
The CoreOS template is not really up to date and in sync with upstream CoreOS « Best Practice » (<a href="https://github.com/coreos/coreos-kubernetes" target="_blank">https://github.com/coreos/coreos-kubernetes</a>), it is more a port of th fedora atomic template
but CoreOS has its own Kubernetes deployment method.<br>
<br>
I’d like to implement the changes to sync kubernetes deployment on CoreOS to latest kubernetes version (1.5.2) along with standards components according the CoreOS Kubernetes guide :<br>
- « Defaults » add ons like kube-dns , heapster and kube-dashboard (kube-ui has been deprecated for a long time and is obsolete)<br>
- Canal for network policy (Calico and Flannel)<br>
- Add support for RKT as container engine<br>
- Support sane default options recommended by Kubernetes upstream (admission control :
<a href="https://kubernetes.io/docs/admin/admission-controllers/" target="_blank">
https://kubernetes.io/docs/admin/admission-controllers/</a>, using service account…)<br>
- Of course add every new parameters to HOT.<br>
<br>
These changes are difficult to implement as is (due to the fragment concept and everything is a bit messy between common and specific template fragment, especially for CoreOS).<br>
<br>
I’m wondering if it is better to clone the CoreOS v1 template to a new v2 template en build from here ?<br>
