New label added to worker nodes

Container Engine for Kubernetes now automatically adds the label to each worker node (compute instance) in a cluster, according to the fault domain in which it is placed.

You can constrain the worker nodes on which to run a pod by including the label in the pod specification.

You'll typically use the label to achieve high availability when a cluster is located in a region with a single availability domain.
