ParamRef

ParamRef describes how to locate the params to be used as input to expressions of rules applied by a policy binding.

namestringname is the name of the resource being referenced.One of `name` or `selector` must be set, but `name` and `selector` are mutually exclusive properties. If one is set, the other must be unset.A single parameter used for all admission requests can be configured by setting the `name` field, leaving `selector` blank, and setting namespace if `paramKind` is namespace-scoped.
namespacestringnamespace is the namespace of the referenced resource. Allows limiting the search for params to a specific namespace. Applies to both `name` and `selector` fields.A per-namespace parameter may be used by specifying a namespace-scoped `paramKind` in the policy and leaving this field empty.
  • If `paramKind` is cluster-scoped, this field MUST be unset. Setting this field results in a configuration error.
  • If `paramKind` is namespace-scoped, the namespace of the object being evaluated for admission will be used when this field is left unset. Take care that if this is left empty the binding must not match any cluster-scoped resources, which will result in an error.
parameterNotFoundActionstringparameterNotFoundAction controls the behavior of the binding when the resource exists, and name or selector is valid, but there are no parameters matched by the binding. If the value is set to `Allow`, then no matched parameters will be treated as successful validation by the binding. If set to `Deny`, then no matched parameters will be subject to the `failurePolicy` of the policy.Allowed values are `Allow` or `Deny`Required
selectorLabelSelectorselector can be used to match multiple param objects based on their labels. Supply selector: {} to match all resources of the ParamKind.If multiple params are found, they are all evaluated with the policy expressions and the results are ANDed together.One of `name` or `selector` must be set, but `name` and `selector` are mutually exclusive properties. If one is set, the other must be unset.
matchExpressions[]LabelSelectorRequirementmatchExpressions is a list of label selector requirements. The requirements are ANDed.
keystring requiredkey is the label key that the selector applies to.
operatorstring requiredoperator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
values[]stringvalues 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.
matchLabelsmap[string]stringmatchLabels 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.
