Struct k8s_openapi::api::admissionregistration::v1beta1::Webhook

pub struct Webhook {
    pub client_config: WebhookClientConfig,
    pub failure_policy: Option<String>,

    pub rules: Option<Vec<RuleWithOperations>>,
    pub side_effects: Option<String>,
}

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

Fields

client_config: WebhookClientConfig

ClientConfig defines how to communicate with the hook. Required

failure_policy: Option<String>

FailurePolicy defines how unrecognized errors from the admission endpoint are handled - allowed values are Ignore or Fail. Defaults to Ignore.

name: String

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.

namespace_selector: Option<LabelSelector>

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.

rules: Option<Vec<RuleWithOperations>>

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.

side_effects: Option<String>

SideEffects states whether this webhookk has side effects. Acceptable values are: Unknown, None, Some, NoneOnDryRun 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. Defaults to Unknown.
