 | `Ready`        | `True` if the node is healthy and ready to accept pods, `False` if the node is not healthy and is not accepting pods, and `Unknown` if the node controller has not heard from the node in the last 40 seconds |

+| `MemoryPressure`    | `True` if pressure exists on the node memory -- that is, if the node memory is low; otherwise `False` |
+| `DiskPressure`    | `True` if pressure exists on the disk size -- that is, if the disk capacity is low; otherwise `False` |
 
 The node condition is represented as a JSON object. For example, the following response describes a healthy node.
