separated from the apiserver running locally on the master node so that it can be optionally enabled or disabled as needed. Also, fix the healthchecking configuration for the master components, which was previously only working by coincidence: If a kubelet doesn't register with a master, it never bothers to figure out what its local address is. In which case it ends up constructing a URL like http://:8080/healthz for the http probe. This happens to work on the master because all of the pods are using host networking and explicitly binding to 127.0.0.1. Once the kubelet is registered with the master and it determines the local node address, it tries to healthcheck on an address where the pod isn't listening and the kubelet periodically restarts each master component when the liveness probe fails.
SaltStack configuration
This is the root of the SaltStack configuration for Kubernetes. A high level overview for the Kubernetes SaltStack configuration can be found in the docs tree.
This SaltStack configuration currently applies to default
configurations for Debian-on-GCE, Fedora-on-Vagrant, Ubuntu-on-AWS and
Ubuntu-on-Azure. (That doesn't mean it can't be made to apply to an
arbitrary configuration, but those are only the in-tree OS/IaaS
combinations supported today.) As you peruse the configuration, these
are shorthanded as gce, vagrant, aws, azure in grains.cloud;
the documentation in this tree uses this same shorthand for convenience.
