matchConditions:
description: |-
MatchConditions is a list of conditions that must be met for a request to be validated.
Match conditions filter requests that have already been matched by the rules,
namespaceSelector, and objectSelector. An empty list of matchConditions matches all requests.
There are a maximum of 64 match conditions allowed.
The exact matching logic is (in order):
1. If ANY matchCondition evaluates to FALSE, the policy is skipped.
2. If ALL matchConditions evaluate to TRUE, the policy is evaluated.
3. If any matchCondition evaluates to an error (but none are FALSE):
- If failurePolicy=Fail, reject the request
- If failurePolicy=Ignore, the policy is skipped

matchPolicy:
description: |-
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"
type: string
namespaceSelector:
description: |-
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

type: object
type: object
x-kubernetes-map-type: atomic
objectSelector:
description: |-
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.

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": [

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",

'JSONPatch' - CEL type of JSON Patch operations.
JSONPatch has the fields 'op', 'from', 'path'
and 'value'.\n See [JSON patch](https://jsonpatch.com/)
for more details. The 'value' field may
be set to any of: string,\n integer, array,
map or object. If set, the 'path' and 'from'
fields must be set to a\n [JSON pointer](https://datatracker.ietf.org/doc/html/rfc6901/)

- CEL type of object field (such as 'Object.spec')\n-
'Object.<fieldName1>.<fieldName2>...<fieldNameN>`
- CEL type of nested field (such as 'Object.spec.containers')\n\nCEL
expressions have access to the contents
of the API request, organized into CEL variables
as well as some other useful variables:\n\n-
'object' - The object from the incoming
request. The value is null for DELETE requests.\n-
'oldObject' - The existing object. The value
is null for CREATE requests.\n- 'request'
- Attributes of the API request([ref](/pkg/apis/admission/types.go#AdmissionRequest)).\n-
'params' - Parameter resource referred to
by the policy binding being evaluated. Only
populated if the policy has a ParamKind.\n-
'namespaceObject' - The namespace object
that the incoming object belongs to. The
value is null for cluster-scoped resources.\n-
'variables' - Map of composited variables,
from its name to its lazily evaluated value.\n
\ For example, a variable named 'foo' can
be accessed as 'variables.foo'.\n- 'authorizer'
- A CEL Authorizer. May be used to perform
authorization checks for the principal (user
or service account) of the request.\n See
https://pkg.go.dev/k8s.io/apiserver/pkg/cel/library#Authz\n-
'authorizer.requestResource' - A CEL ResourceCheck
constructed from the 'authorizer' and configured
with the\n request resource.\n\nCEL expressions
have access to [Kubernetes CEL function
libraries](https://kubernetes.io/docs/reference/using-api/cel/#cel-options-language-features-and-libraries)\nas
well as:\n\n- 'jsonpatch.escapeKey' - Performs
JSONPatch key escaping. '~' and '/' are
escaped as '~0' and `~1' respectively).\n\nOnly

1. If ANY matchCondition evaluates to FALSE, the policy is skipped.
2. If ALL matchConditions evaluate to TRUE, the policy is evaluated.
3. If any matchCondition evaluates to an error (but none are FALSE):
- If failurePolicy=Fail, reject the request
- If failurePolicy=Ignore, the policy is skipped

ResourceRules describes what operations on what resources/subresources the ValidatingAdmissionPolicy matches.
The policy cares about an operation if it matches _any_ Rule.
items:
description: NamedRuleWithOperations is a tuple
of Operations and Resources with ResourceNames.
properties:
apiGroups:
description: |-
APIGroups is the API groups the resources belong to. '*' is all groups.
If '*' is present, the length of the slice must be one.
Required.
items:
type: string
type: array
x-kubernetes-list-type: atomic
apiVersions:
description: |-
APIVersions is the API versions the resources belong to. '*' is all versions.
If '*' is present, the length of the slice must be one.
Required.
items:
type: string
type: array
x-kubernetes-list-type: atomic
operations:
description: |-
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.
items:
description: OperationType specifies an
operation for a request.
type: string
type: array
x-kubernetes-list-type: atomic
resourceNames:
description: ResourceNames is an optional
white list of names that the rule applies
to. An empty set means that everything
is allowed.
items:
type: string
type: array
x-kubernetes-list-type: atomic
resources:
description: |-
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.
items:
type: string
type: array
x-kubernetes-list-type: atomic
scope:
description: |-
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 "*".

variables:
description: |-
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.
items:
description: Variable is the definition of a variable
that is used for composition. A variable is defined
as a named expression.
properties:
expression:
description: |-
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.
type: string
name:
description: |-
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`

webhookConfiguration:
description: WebhookConfiguration defines the configuration
for the webhook.
properties:
timeoutSeconds:
description: |-
TimeoutSeconds specifies the maximum time in seconds allowed to apply this policy.
After the configured time expires, the admission request may fail, or may simply ignore the policy results,
based on the failure policy. The default timeout is 10s, the value must be between 1 and 30 seconds.

conditions:
items:
description: Condition contains details for one aspect of the
current state of this API Resource.
properties:
lastTransitionTime:
description: |-
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.
