+kops can be used to create a highly available cluster, with multiple master and worker nodes spread across multiple availability zones.
 The master and worker nodes within the cluster can use either DNS or the https://github.com/weaveworks/mesh[Weave Mesh, window="_blank"] *gossip* protocol for name resolution.  For this workshop, we will use the gossip protocol.  A gossip-based cluster is easier and quicker to setup, and does not does not require a domain, subdomain, or Route53 hosted zone to be registered. Instructions for creating a DNS-based cluster are provided as an appendix at the bottom of this page.
 
 To create a cluster using the gossip protocol, simply use a cluster name with a suffix of `.k8s.local`. In the following steps, we will use `example.cluster.k8s.local` as a sample gossip cluster name. You may choose a different name as long as it ends with `.k8s.local`.

 Kubernetes resources are created with a specific API version. The exact value is defined by the `apiVersion` attribute in the resource configuration file. Some of the values are `v1`, `extensions/v1beta1` or `batch/v1`. By default, resources with `apiVersion` values X, Y, Z are enabled. If a resource has a version with the word `alpha` in it, then that version needs to be explicitly enabled in the cluster.
