### Node Condition
Node Condition describes the conditions of `Running` nodes. Current valid
conditions are `NodeReachable`, `NodeReady` and `NodeSchedulable`. In the
future, we plan to add more. `NodeReachable` means the node can be reached
within the cluster. `NodeReady` means the kubelet returns StatusOK for HTTP
health check. `NodeSchedulable` means node is allowed to schedule any new
pods and is controlled by 'unschedulable' field in node spec.
Different condition provides different level of understanding for node
health. Kubernetes will make a comprehensive scheduling decision based on the
information. Node condition is represented as a json object. For example, the
following conditions mean the node is reachable from its cluster, node is in
sane state but not allowed to accept new pods:
