MutatingAdmissionPolicyBinding admissionregistration.k8s.io/v1

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)

NamedRuleWithOperations is a tuple of Operations and Resources with ResourceNames.

excludeResourceRules.apiGroups ([]string)

apiGroups is the API groups the resources belong to. '' is all groups. If '' is present, the length of the slice must be one. Required.

excludeResourceRules.apiVersions ([]string)

apiVersions is the API versions the resources belong to. '' is all versions. If '' is present, the length of the slice must be one. Required.

excludeResourceRules.operations ([]string)

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.

excludeResourceRules.resourceNames ([]string)

resourceNames is an optional white list of names that the rule applies to. An empty set means that everything is allowed.

excludeResourceRules.resources ([]string)

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.

excludeResourceRules.scope (string)

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.

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.

NamedRuleWithOperations is a tuple of Operations and Resources with ResourceNames.

resourceRules.apiGroups ([]string)

apiGroups is the API groups the resources belong to. '' is all groups. If '' is present, the length of the slice must be one. Required.

resourceRules.apiVersions ([]string)

apiVersions is the API versions the resources belong to. '' is all versions. If '' is present, the length of the slice must be one. Required.

resourceRules.operations ([]string)

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.

resourceRules.resourceNames ([]string)

resourceNames is an optional white list of names that the rule applies to. An empty set means that everything is allowed.

resourceRules.resources ([]string)

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.

resourceRules.scope (string)

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 "*".

name 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.

namespace 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.

parameterNotFoundAction 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

selector 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.
