A node selector requirement is a selector that contains values, a key, and an operator that relates the key and values.

---

• key (string), required

  The label key that the selector applies to.

• operator (string), required

  Represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists, DoesNotExist. Gt, and Lt.

• values ([]string)

  An array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. If the operator is Gt or Lt, the values array must have a single element, which will be interpreted as an integer. This array is replaced during a strategic merge patch.
