type ValidationRule added in v0.23.0 

type ValidationRule struct {
	// Rule represents the expression which will be evaluated by CEL.
	// ref: https://github.com/google/cel-spec
	// The Rule is scoped to the location of the x-kubernetes-validations extension in the schema.
	// The `self` variable in the CEL expression is bound to the scoped value.
	// Example:
	// - Rule scoped to the root of a resource with a status subresource: {"rule": "self.status.actual <= self.spec.maxDesired"}
	//
	// If the Rule is scoped to an object with properties, the accessible properties of the object are field selectable
	// via `self.field` and field presence can be checked via `has(self.field)`. Null valued fields are treated as
	// absent fields in CEL expressions.
	// If the Rule is scoped to an object with additionalProperties (i.e. a map) the value of the map
	// are accessible via `self[mapKey]`, map containment can be checked via `mapKey in self` and all entries of the map
	// are accessible via CEL macros and functions such as `self.all(...)`.
	// If the Rule is scoped to an array, the elements of the array are accessible via `self[i]` and also by macros and
	// functions.
	// If the Rule is scoped to a scalar, `self` is bound to the scalar value.
	// Examples:
	// - Rule scoped to a map of objects: {"rule": "self.components['Widget'].priority < 10"}
	// - Rule scoped to a list of integers: {"rule": "self.values.all(value, value >= 0 && value < 100)"}
	// - Rule scoped to a string value: {"rule": "self.startsWith('kube')"}
	//
	// The `apiVersion`, `kind`, `metadata.name` and `metadata.generateName` are always accessible from the root of the
	// object and from any x-kubernetes-embedded-resource annotated objects. No other metadata properties are accessible.
	//
	// Unknown data preserved in custom resources via x-kubernetes-preserve-unknown-fields is not accessible in CEL
	// expressions. This includes:
	// - Unknown field values that are preserved by object schemas with x-kubernetes-preserve-unknown-fields.
	// - Object properties where the property schema is of an "unknown type". An "unknown type" is recursively defined as:
	//   - A schema with no type and x-kubernetes-preserve-unknown-fields set to true
	//   - An array where the items schema is of an "unknown type"
	//   - An object where the additionalProperties schema is of an "unknown type"
	//
	// Only property names of the form `[a-zA-Z_.-/][a-zA-Z0-9_.-/]*` are accessible.
	// Accessible property names are escaped according to the following rules when accessed in the expression:
	// - '__' escapes to '__underscores__'
	// - '.' escapes to '__dot__'
	// - '-' escapes to '__dash__'
	// - '/' escapes to '__slash__'
	// - Property names that exactly match a CEL RESERVED keyword escape to '__{keyword}__'. The keywords are:
	//	  "true", "false", "null", "in", "as", "break", "const", "continue", "else", "for", "function", "if",
	//	  "import", "let", "loop", "package", "namespace", "return".
	// Examples:
	//   - Rule accessing a property named "namespace": {"rule": "self.__namespace__ > 0"}
	//   - Rule accessing a property named "x-prop": {"rule": "self.x__dash__prop > 0"}
	//   - Rule accessing a property named "redact__d": {"rule": "self.redact__underscores__d > 0"}
	//
	// Equality on arrays with x-kubernetes-list-type of 'set' or 'map' ignores element order, i.e. [1, 2] == [2, 1].
	// Concatenation on arrays with x-kubernetes-list-type use the semantics of the list type:
	//   - 'set': `X + Y` performs a union where the array positions of all elements in `X` are preserved and
	//     non-intersecting elements in `Y` are appended, retaining their partial order.
	//   - 'map': `X + Y` performs a merge where the array positions of all keys in `X` are preserved but the values
	//     are overwritten by values in `Y` when the key sets of `X` and `Y` intersect. Elements in `Y` with
	//     non-intersecting keys are appended, retaining their partial order.
	Rule string
	// Message represents the message displayed when validation fails. The message is required if the Rule contains
	// line breaks. The message must not contain line breaks.
	// If unset, the message is "failed rule: {Rule}".
	// e.g. "must be a URL with the host matching spec.host"
	Message string
	// MessageExpression declares a CEL expression that evaluates to the validation failure message that is returned when this rule fails.
	// Since messageExpression is used as a failure message, it must evaluate to a string.
	// If both message and messageExpression are present on a rule, then messageExpression will be used if validation
	// fails. If messageExpression results in a runtime error, the runtime error is logged, and the validation failure message is produced
	// as if the messageExpression field were unset. If messageExpression evaluates to an empty string, a string with only spaces, or a string
	// that contains line breaks, then the validation failure message will also be produced as if the messageExpression field were unset, and
	// the fact that messageExpression produced an empty string/string with only spaces/string with line breaks will be logged.
	// messageExpression has access to all the same variables as the rule; the only difference is the return type.
	// Example:
	// "x must be less than max ("+string(self.max)+")"
	// +optional
	MessageExpression string
	// reason provides a machine-readable validation failure reason that is returned to the caller when a request fails this validation rule.
	// The HTTP status code returned to the caller will match the reason of the reason of the first failed validation rule.
	// The currently supported reasons are: "FieldValueInvalid", "FieldValueForbidden", "FieldValueRequired", "FieldValueDuplicate".
	// If not set, default to use "FieldValueInvalid".
	// All future added reasons must be accepted by clients when reading this value and unknown reasons should be treated as FieldValueInvalid.
	// +optional
	Reason *FieldValueErrorReason
	// fieldPath represents the field path returned when the validation fails.
	// It must be a relative JSON path (i.e. with array notation) scoped to the location of this x-kubernetes-validations extension in the schema and refer to an existing field.
	// e.g. when validation checks if a specific attribute `foo` under a map `testMap`, the fieldPath could be set to `.testMap.foo`
	// If the validation checks two lists must have unique attributes, the fieldPath could be set to either of the list: e.g. `.testList`
	// It does not support list numeric index.
	// It supports child operation to refer to an existing field currently. Refer to [JSONPath support in Kubernetes](https://kubernetes.io/docs/reference/kubectl/jsonpath/) for more info.
	// Numeric index of array is not supported.
	// For field name which contains special characters, use `['specialName']` to refer the field name.
	// e.g. for attribute `foo.34$` appears in a list `testList`, the fieldPath could be set to `.testList['foo.34$']`
	// +optional
	FieldPath string
}

type WebhookClientConfig

	//
	// The `host` should not refer to a service running in the cluster; use
	// the `service` field instead. The host might be resolved via external
	// DNS in some apiservers (e.g., `kube-apiserver` cannot resolve
	// in-cluster DNS as that would be a layering violation). `host` may
	// also be an IP address.
	//
	// Please note that using `localhost` or `127.0.0.1` as a `host` is
	// risky unless you take great care to run this webhook on all hosts
	// which run an apiserver which might need to make calls to this
	// webhook. Such installs are likely to be non-portable, i.e., not easy
	// to turn up in a new cluster.
	//
	// The scheme must be "https"; the URL must begin with "https://".
	//
	// A path is optional, and if present may be any string permissible in
