MutatingWebhook

class lightkube.models.admissionregistration_v1.MutatingWebhook(admissionReviewVersions, clientConfig, name, sideEffects, failurePolicy=None, matchPolicy=None, namespaceSelector=None, objectSelector=None, reinvocationPolicy=None, rules=None, timeoutSeconds=None)

MutatingWebhook describes an admission webhook and the resources and operations it applies to.

parameters

  • admissionReviewVersions List[str] - AdmissionReviewVersions is an ordered list of preferred AdmissionReview versions the Webhook expects. API server will try to use first version in the list which it supports. If none of the versions specified in this list supported by API server, validation will fail for this object. If a persisted webhook configuration specifies allowed versions and does not include any versions known to the API Server, calls to the webhook will fail and be subject to the failure policy.
  • clientConfig WebhookClientConfig - ClientConfig defines how to communicate with the hook. Required
  • name str - The name of the admission webhook. Name should be fully qualified, e.g., imagepolicy.kubernetes.io, where "imagepolicy" is the name of the webhook, and kubernetes.io is the name of the organization. Required.
  • sideEffects str - SideEffects 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 chain 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.
  • failurePolicy str - (optional) FailurePolicy defines how unrecognized errors from the admission endpoint are handled - allowed values are Ignore or Fail. Defaults to Fail.
  • matchPolicy str - (optional) matchPolicy 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"
  • namespaceSelector meta_v1.LabelSelector - (optional) NamespaceSelector 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.
  • objectSelector meta_v1.LabelSelector - (optional) ObjectSelector 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.
  • reinvocationPolicy str - (optional) reinvocationPolicy indicates whether this webhook should be called multiple times as part of a single admission evaluation. Allowed values are "Never" and "IfNeeded". Never: the webhook will not be called more than once in a single admission evaluation. IfNeeded: the webhook will be called at least one additional time as part of the admission evaluation if the object being admitted is modified by other admission plugins after the initial webhook call. Webhooks that specify this option must be idempotent, able to process objects they previously admitted. Note: * the number of additional invocations is not guaranteed to be exactly one. * if additional invocations result in further modifications to the object, webhooks are not guaranteed to be invoked again. * webhooks that use this option may be reordered to minimize the number of additional invocations.
  • to validate an object after all mutations are guaranteed complete, use a validating admission webhook instead. Defaults to "Never".
  • rules RuleWithOperations - (optional) Rules describes what operations on what resources/subresources the webhook cares about. The webhook cares about an operation if it matches any Rule. However, in order to prevent ValidatingAdmissionWebhooks and MutatingAdmissionWebhooks from putting the cluster in a state which cannot be recovered from without completely disabling the plugin, ValidatingAdmissionWebhooks and MutatingAdmissionWebhooks are never called on admission requests for ValidatingWebhookConfiguration and MutatingWebhookConfiguration objects.
  • timeoutSeconds int - (optional) TimeoutSeconds 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.

ValidatingWebhookConfiguration

class lightkube.models.admissionregistration_v1.ValidatingWebhookConfiguration(apiVersion=None, kind=None, metadata=None, webhooks=None)

ValidatingWebhookConfiguration describes the configuration of and admission webhook that accept or reject and object without changing it.

parameters

  • apiVersion str - (optional) 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
  • kind str - (optional) 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
  • metadata meta_v1.ObjectMeta - (optional) Standard object metadata; More info
  • webhooks ValidatingWebhook - (optional) Webhooks is a list of webhooks and the affected resources and operations.

ValidatingWebhookConfigurationList

class lightkube.models.admissionregistration_v1.ValidatingWebhookConfigurationList(items, apiVersion=None, kind=None, metadata=None)

ValidatingWebhookConfigurationList is a list of ValidatingWebhookConfiguration.

parameters

  • items ValidatingWebhookConfiguration - List of ValidatingWebhookConfiguration.
  • apiVersion str - (optional) 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
  • kind str - (optional) 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
  • metadata meta_v1.ListMeta - (optional) Standard list metadata. More info

WebhookClientConfig

class lightkube.models.admissionregistration_v1.WebhookClientConfig(caBundle=None, service=None, url=None)

WebhookClientConfig contains the information to make a TLS connection with the webhook

parameters

  • caBundle str - (optional) caBundle is a PEM encoded CA bundle which will be used to validate the webhook's server certificate. If unspecified, system trust roots on the apiserver are used.
  • service ServiceReference - (optional) service is a reference to the service for this webhook. Either service or url must be specified. If the webhook is running within the cluster, then you should use service.
  • url str - (optional) url gives the location of the webhook, in standard URL form (scheme://host:port/path). Exactly one of url or service must be specified. 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 a URL. You may use the path to pass an arbitrary string to the webhook, for example, a cluster identifier. Attempting to use a user or basic auth e.g. "user:password@" is not allowed. Fragments ("#...") and query parameters ("?...") are not allowed, either.
