What is the correct way to install addons with Kubernetes 1.1? The docs aren't as clear as I'd like on this subject; they seem to imply that one should copy addons' yaml files to /etc/kubernetes/addons on master nodes, but I have tried this and nothing happens.
Additionally, for added confusion, the docs imply that addons are bundled with Kubernetes:
So the only persistent way to make changes in add-ons is to update the manifests on the master server. But still, users are discouraged to do it on their own - they should rather wait for a new release of Kubernetes that will also contain new versions of add-ons.
So, how should I really install addons, f.ex. cluster-loadbalancing, with Kubernetes 1.1?

This is only true if you are using one of the salt-based installation mechanisms.

Most of the add-ons can be installed by just running kubectl create -f against the replication controller and service files for the add-on. You need to create the kube-system namespace first if you haven't already, and some of the add-ons (like dns) require you to fill in a few values in a jinja template that would otherwise be handled by salt.
