 In the Kubernetes API, a node's condition is represented as part of the `.status`
 of the Node resource. For example, the following JSON structure describes a healthy node:
 
-```json

-    "reason": "KubeletReady",

 When problems occur on nodes, the Kubernetes control plane automatically creates
 [taints](/docs/concepts/scheduling-eviction/taint-and-toleration/) that match the conditions
 affecting the node. An example of this is when the `status` of the Ready condition
 remains `Unknown` or `False` for longer than the kube-controller-manager's `NodeMonitorGracePeriod`,
-which defaults to 50 seconds. This will cause either an `node.kubernetes.io/unreachable` taint, for an `Unknown` status,
