Kubernetes cluster fleet viewer

Clusters are the new cattle and we should have tooling available that allows us to quickly get an idea what's going in a fleet of such clusters.

What is this about?

Meet fleet, a simple CLI tool that provides you with the status and configuration of a fleet of Kubernetes clusters. For example:

$ kubectl fleet
CLUSTER                     VERSION            NODES NAMESPACES API
mngbase.us-west-2.eksctl.io v1.14.8-eks-41be3d 2     5          https://123456789ABCDEF.gr7.us-west-2.eks.amazonaws.com
kind-mh9local               v1.16.3            1     4          https://127.0.0.1:58836

Above, you see fleet used as a kubectl plugin, available via krew. The top-level command lists all active clusters found in the kubeconfig provided. Active clusters are defined as the one that you would see when you'd execute the kubectl config get-contexts command. For each cluster, configuration info such as the control plane version or API server endpoint are displayed, as well as select stats, for example, the number of worker nodes or namespaces found in the cluster.

Note that you can also use it standalone, simply download the binary for your platform from the release page.
