AdmissionPolicySpec​

AdmissionPolicySpec defines the desired state of AdmissionPolicy.

Appears in:

FieldDescription
policyServer stringPolicyServer identifies an existing PolicyServer resource.
module stringModule is the location of the WASM module to be loaded. Can be a local file (file://), a remote file served by an HTTP server (http://, https://), or an artifact served by an OCI-compatible registry (registry://). If prefix is missing, it will default to registry:// and use that internally.
mode PolicyModeMode defines the execution mode of this policy. Can be set to either "protect" or "monitor". If it's empty, it is defaulted to "protect". Transitioning this setting from "monitor" to "protect" is allowed, but is disallowed to transition from "protect" to "monitor". To perform this transition, the policy should be recreated in "monitor" mode instead.
settings RawExtensionSettings is a free-form object that contains the policy configuration values. x-kubernetes-embedded-resource: false
rules RuleWithOperations arrayRules describes what operations on what resources/subresources the webhook cares about. The webhook cares about an operation if it matches any Rule.
failurePolicy FailurePolicyTypeFailurePolicy defines how unrecognized errors and timeout errors from the policy are handled. Allowed values are "Ignore" or "Fail". * "Ignore" means that an error calling the webhook is ignored and the API request is allowed to continue. * "Fail" means that an error calling the webhook causes the admission to fail and the API request to be rejected. The default behaviour is "Fail"
mutating booleanMutating indicates whether a policy has the ability to mutate incoming requests or not.
backgroundAudit booleanBackgroundAudit indicates whether a policy should be used or skipped when performing audit checks. If false, the policy cannot produce meaningful evaluation results during audit checks and will be skipped. The default is "true".
matchPolicy MatchPolicyTypematchPolicy defines how the "rules" 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 webhook.
  • 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 webhook.
Defaults to "Equivalent"
matchConditions MatchCondition arrayMatchConditions are 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. If a parameter object is provided, it can be accessed via the params handle in the same manner as validation expressions. 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. Only available if the feature gate AdmissionWebhookMatchConditions is enabled.
objectSelector LabelSelectorObjectSelector decides whether to run the webhook based on if the object has matching labels. objectSelector is evaluated against both the oldObject and newObject that would be sent to the webhook, 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.
sideEffects SideEffectClassSideEffects states whether this webhook has side effects. Acceptable values are: None, NoneOnDryRun (webhooks created via v1beta1 may also specify Some or Unknown). Webhooks with side effects MUST implement a reconciliation system, since a request may be rejected by a future step in the admission change and the side effects therefore need to be undone. Requests with the dryRun attribute will be auto-rejected if they match a webhook with sideEffects == Unknown or Some.
timeoutSeconds integerTimeoutSeconds specifies the timeout for this webhook. After the timeout passes, the webhook call will be ignored or the API call will fail based on the failure policy. The timeout value must be between 1 and 30 seconds. Default to 10 seconds.

namespaceSelector LabelSelectorNamespaceSelector decides whether to run the webhook 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 webhook.

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 webhook 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.

backgroundAudit booleanBackgroundAudit indicates whether a policy should be used or skipped when performing audit checks. If false, the policy cannot produce meaningful evaluation results during audit checks and will be skipped. The default is true.
expression stringExpression is the evaluation expression to accept or reject the admission request under evaluation. This field uses CEL as the expression language for the policy groups. Each policy in the group will be represented as a function call in the expression with the same name as the policy defined in the group. The expression field should be a valid CEL expression that evaluates to a boolean value. If the expression evaluates to true, the group policy will be considered as accepted, otherwise, it will be considered as rejected. This expression allows grouping policies calls and perform logical operations on the results of the policies. See Kubewarden documentation to learn about all the features available.
failurePolicy FailurePolicyTypeFailurePolicy defines how unrecognized errors and timeout errors from the policy are handled. Allowed values are Ignore or Fail.
  • Ignore means that an error calling the webhook is ignored and the API request is allowed to continue.

Only available if the feature gate AdmissionWebhookMatchConditions is enabled.
matchPolicy MatchPolicyTypematchPolicy defines how the rules 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 webhook.
  • 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 webhook.
Defaults to Equivalent
message stringMessage is used to specify the message that will be returned when the policy group is rejected. The specific policy results will be returned in the warning field of the response.
mode PolicyModeMode defines the execution mode of this policy. Can be set to either protect or monitor. If it's empty, it is defaulted to protect. Transitioning this setting from monitor to protect is allowed, but is disallowed to transition from protect to monitor.

module stringModule is the location of the WASM module to be loaded. Can be a local file (file://), a remote file served by an HTTP server (http://, https://), or an artifact served by an OCI-compatible registry (registry://). If prefix is missing, it will default to registry:// and use that internally.
mode PolicyModeMode defines the execution mode of this policy. Can be set to either "protect" or "monitor". If it's empty, it is defaulted to "protect". Transitioning this setting from "monitor" to "protect" is allowed, but is disallowed to transition from "protect" to "monitor". To perform this transition, the policy should be recreated in "monitor" mode instead.
settings RawExtensionSettings is a free-form object that contains the policy configuration values. x-kubernetes-embedded-resource: false
rules RuleWithOperations arrayRules describes what operations on what resources/subresources the webhook cares about. The webhook cares about an operation if it matches any Rule.
failurePolicy FailurePolicyTypeFailurePolicy defines how unrecognized errors and timeout errors from the policy are handled. Allowed values are "Ignore" or "Fail". * "Ignore" means that an error calling the webhook is ignored and the API request is allowed to continue. * "Fail" means that an error calling the webhook causes the admission to fail and the API request to be rejected. The default behaviour is "Fail"
mutating booleanMutating indicates whether a policy has the ability to mutate incoming requests or not.
backgroundAudit booleanBackgroundAudit indicates whether a policy should be used or skipped when performing audit checks. If false, the policy cannot produce meaningful evaluation results during audit checks and will be skipped. The default is "true".
matchPolicy MatchPolicyTypematchPolicy defines how the "rules" 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 webhook.
  • 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 webhook.
Defaults to "Equivalent"
matchConditions MatchCondition arrayMatchConditions are 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. If a parameter object is provided, it can be accessed via the params handle in the same manner as validation expressions. 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. Only available if the feature gate AdmissionWebhookMatchConditions is enabled.
objectSelector LabelSelectorObjectSelector decides whether to run the webhook based on if the object has matching labels. objectSelector is evaluated against both the oldObject and newObject that would be sent to the webhook, 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.
sideEffects SideEffectClassSideEffects states whether this webhook has side effects. Acceptable values are: None, NoneOnDryRun (webhooks created via v1beta1 may also specify Some or Unknown). Webhooks with side effects MUST implement a reconciliation system, since a request may be rejected by a future step in the admission change and the side effects therefore need to be undone. Requests with the dryRun attribute will be auto-rejected if they match a webhook with sideEffects == Unknown or Some.
timeoutSeconds integerTimeoutSeconds specifies the timeout for this webhook. After the timeout passes, the webhook call will be ignored or the API call will fail based on the failure policy. The timeout value must be between 1 and 30 seconds. Default to 10 seconds.

module stringModule is the location of the WASM module to be loaded. Can be a local file (file://), a remote file served by an HTTP server (http://, https://), or an artifact served by an OCI-compatible registry (registry://).
mode PolicyModeMode defines the execution mode of this policy. Can be set to either "protect" or "monitor". If it's empty, it is defaulted to "protect". Transitioning this setting from "monitor" to "protect" is allowed, but is disallowed to transition from "protect" to "monitor". To perform this transition, the policy should be recreated in "monitor" mode instead.
settings RawExtensionSettings is a free-form object that contains the policy configuration values. x-kubernetes-embedded-resource: false
rules RuleWithOperations arrayRules describes what operations on what resources/subresources the webhook cares about. The webhook cares about an operation if it matches any Rule.
failurePolicy FailurePolicyTypeFailurePolicy defines how unrecognized errors and timeout errors from the policy are handled. Allowed values are "Ignore" or "Fail". * "Ignore" means that an error calling the webhook is ignored and the API request is allowed to continue. * "Fail" means that an error calling the webhook causes the admission to fail and the API request to be rejected. The default behaviour is "Fail"
mutating booleanMutating indicates whether a policy has the ability to mutate incoming requests or not.
matchPolicy MatchPolicyTypematchPolicy defines how the "rules" 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 webhook.
  • 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 webhook.

namespaceSelector LabelSelectorNamespaceSelector decides whether to run the webhook 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 webhook.

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 webhook 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.
