This blog post will cover how well Kubernetes is supported on Azure today, and where there is still room to improve.

#### Upgrading Kubernetes (e.g. to 1.5.1) {#upgrading}
The Kubernetes cluster you get is currently a 1.4.6 cluster. This is not bad, it's a stable version, but currently you can't influence it in a convenient way. It's 1.4.6 you get, period. Kubernets on Azure being the standard version though, it's possible to do a manual upgrade of the Kubernetes version, as one of the [issues on Cole Mickens' `azure-kubernetes-status` repository](https://github.com/colemickens/azure-kubernetes-status/issues/15) suggests.

I raised an issue on the Azure Support asking for how this will be done once Kubernetes on Azure reaches GA (General Availability), and the answer I got for this was that it's a "reasonable expectation" that there either will be explicit support for automatically upgrading the Kubernetes components, **or** that there will be documentation on how to accomplish this manually, as part of the official documentation of the Azure Container Service. Both options are valid in my opinion.
