APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
DeletingPolicySpec is the specification of the desired behavior of the DeletingPolicy.
Conditions is a list of conditions that must be met for a resource to be deleted. Conditions filter resources that have already been matched by the match constraints, namespaceSelector, and objectSelector. An empty list of conditions matches all resources. There are a maximum of 64 conditions allowed. The exact matching logic is (in order): 1. If ANY condition evaluates to FALSE, the policy is skipped. 2. If ALL conditions evaluate to TRUE, the policy is executed.
expression represents the expression which will be evaluated by CEL. Must evaluate to bool. CEL expressions have access to the contents of the AdmissionRequest and Authorizer, organized into CEL variables: 'object' - The object from the incoming request. The value is null for DELETE requests. 'oldObject' - The existing object. The value is null for CREATE requests. 'request' - Attributes of the admission request(/pkg/apis/admission/types.go#AdmissionRequest). 'authorizer' - A CEL Authorizer. May be used to perform authorization checks for the principal (user or service account) of the request. See https://pkg.go.dev/k8s.io/apiserver/pkg/cel/library#Authz 'authorizer.requestResource' - A CEL ResourceCheck constructed from the 'authorizer' and configured with the request resource. Documentation on CEL: https://kubernetes.io/docs/reference/using-api/cel/ Required.
name is an identifier for this match condition, used for strategic merging of MatchConditions, as well as providing an identifier for logging purposes. A good name should be descriptive of the associated expression. Name must be a qualified name consisting of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyName', or 'my.name', or '123-abc', regex used for validation is '([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9]') with an optional DNS subdomain prefix and '/' (e.g. 'example.com/MyName') Required.
DeletionPropagationPolicy defines how resources will be deleted (Foreground, Background, Orphan).
MatchConstraints specifies what resources this policy is designed to validate. The AdmissionPolicy cares about a request if it matches _all_ Constraints. Required.
excludeResourceRules describes what operations on what resources/subresources the ValidatingAdmissionPolicy should not care about. The exclude rules take precedence over include rules (if a resource matches both, it is excluded)
apiGroups is the API groups the resources belong to. '*' is all groups. If '*' is present, the length of the slice must be one. Required.
apiVersions is the API versions the resources belong to. '*' is all versions. If '*' is present, the length of the slice must be one. Required.
operations is the operations the admission hook cares about - CREATE, UPDATE, DELETE, CONNECT or * for all of those operations and any future admission operations that are added. If '*' is present, the length of the slice must be one. Required.
resourceNames is an optional white list of names that the rule applies to. An empty set means that everything is allowed.
resources is a list of resources this rule applies to. For example: 'pods' means pods. 'pods/log' means the log subresource of pods. '*' means all resources, but not subresources. 'pods/*' means all subresources of pods. '*/scale' means all scale subresources. '*/*' means all resources and their subresources. If wildcard is present, the validation rule will ensure resources do not overlap with each other. Depending on the enclosing object, subresources might not be allowed. Required.
scope specifies the scope of this rule. Valid values are "Cluster", "Namespaced", and "*" "Cluster" means that only cluster-scoped resources will match this rule. Namespace API objects are cluster-scoped. "Namespaced" means that only namespaced resources will match this rule. "*" means that there are no scope restrictions. Subresources match the scope of their parent resource. Default is "*".
matchPolicy defines how the "MatchResources" list is used to match incoming requests. Allowed values are "Exact" or "Equivalent". - Exact: match a request only if it exactly matches a specified rule. For example, if deployments can be modified via apps/v1, apps/v1beta1, and extensions/v1beta1, but "rules" only included `apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"]`, a request to apps/v1beta1 or extensions/v1beta1 would not be sent to the ValidatingAdmissionPolicy. - Equivalent: match a request if modifies a resource listed in rules, even via another API group or version. For example, if deployments can be modified via apps/v1, apps/v1beta1, and extensions/v1beta1, and "rules" only included `apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"]`, a request to apps/v1beta1 or extensions/v1beta1 would be converted to apps/v1 and sent to the ValidatingAdmissionPolicy. Defaults to "Equivalent"
namespaceSelector decides whether to run the admission control policy on an object based on whether the namespace for that object matches the selector. If the object itself is a namespace, the matching is performed on object.metadata.labels. If the object is another cluster scoped resource, it never skips the policy. For example, to run the webhook on any objects whose namespace is not associated with "runlevel" of "0" or "1"; you will set the selector as follows: "namespaceSelector": { "matchExpressions": [ { "key": "runlevel", "operator": "NotIn", "values": [ "0", "1" ] } ] } If instead you want to only run the policy on any objects whose namespace is associated with the "environment" of "prod" or "staging"; you will set the selector as follows: "namespaceSelector": { "matchExpressions": [ { "key": "environment", "operator": "In", "values": [ "prod", "staging" ] } ] } See https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/ for more examples of label selectors. Default to the empty LabelSelector, which matches everything.
matchExpressions is a list of label selector requirements. The requirements are ANDed.
key is the label key that the selector applies to.
operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
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.
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.
objectSelector decides whether to run the validation based on if the object has matching labels. objectSelector is evaluated against both the oldObject and newObject that would be sent to the cel validation, and is considered to match if either object matches the selector. A null object (oldObject in the case of create, or newObject in the case of delete) or an object that cannot have labels (like a DeploymentRollback or a PodProxyOptions object) is not considered to match. Use the object selector only if the webhook is opt-in, because end users may skip the admission webhook by setting the labels. Default to the empty LabelSelector, which matches everything.

resourceRules describes what operations on what resources/subresources the ValidatingAdmissionPolicy matches. The policy cares about an operation if it matches _any_ Rule.
apiGroups is the API groups the resources belong to. '*' is all groups. If '*' is present, the length of the slice must be one. Required.
apiVersions is the API versions the resources belong to. '*' is all versions. If '*' is present, the length of the slice must be one. Required.

Namespace API objects are cluster-scoped. "Namespaced" means that only namespaced resources will match this rule. "*" means that there are no scope restrictions. Subresources match the scope of their parent resource. Default is "*".
The schedule in Cron format Required.
Variables contain definitions of variables that can be used in composition of other expressions. Each variable is defined as a named CEL expression. The variables defined here will be available under `variables` in other expressions of the policy except MatchConditions because MatchConditions are evaluated before the rest of the policy. The expression of a variable can refer to other variables defined earlier in the list but not those after. Thus, Variables must be sorted by the order of first appearance and acyclic.
expression is the expression that will be evaluated as the value of the variable. The CEL expression has access to the same identifiers as the CEL expressions in Validation.
name is the name of the variable. The name must be a valid CEL identifier and unique among all variables. The variable can be accessed in other expressions through `variables` For example, if name is "foo", the variable will be available as `variables.foo`
Status contains policy runtime data.
ConditionStatus is the shared status across all policy types
lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.
message is a human readable message indicating details about the transition. This may be an empty string.
observedGeneration represents the .metadata.generation that the condition was set based upon. For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date with respect to the current state of the instance.
reason contains a programmatic identifier indicating the reason for the condition's last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty.
status of the condition, one of True, False, Unknown.
type of condition in CamelCase or in foo.example.com/CamelCase.
Message is a human readable message indicating details about the generation of ValidatingAdmissionPolicy/MutatingAdmissionPolicy It is an empty string when ValidatingAdmissionPolicy/MutatingAdmissionPolicy is successfully generated.
The ready of a policy is a high-level summary of where the policy is in its lifecycle. The conditions array, the reason and message fields contain more detail about the policy's status.
