LabelSelector
A label selector is a label query over a set of resources. The result of matchLabels and matchExpressions are ANDed. An empty label selector matches all objects. A null label selector matches no objects.
- matchExpressions ([]LabelSelectorRequirement)
matchExpressions is a list of label selector requirements. The requirements are ANDed.
A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values.- matchExpressions.key (string), required
Patch strategy: merge on keykey
key is the label key that the selector applies to. - matchExpressions.operator (string), required
operator represents a key’s relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist. - matchExpressions.values ([]string)
values is 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. This array is replaced during a strategic merge patch.
- matchExpressions.key (string), required
- matchLabels (map[string]string)
matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is “key”, the operator is “In”, and the values array contains only “value”. The requirements are ANDed.
