ssh-check

Check ssh connectivity to nodes within a cluster

This check requires two environment variables in the kube spec used to deploy it. An ssh key, and the user.

SSH Exclude List

The exclude list is a space delimited list of node names that the user would like to exclude from the ssh check.
