nitialSeats : The number of seats will be occupied during the initial (normal) stage of execution of the request. FinalSeats : The number of seats will be occupied during the final stage of request execution, accounting for the associated WATCH notifications.• ◦ ◦ ◦

AdditionalLatency : The extra time taken during the final stage of request execution. FinalSeats will be occupied during this time period. It does not mean any latency that a user will observe. StartTime : The time a request starts to execute. It will be 0001-01-01T00:00:00Z for queued requests. Debug logging At -v=3 or more verbosity, the API server outputs an httplog line for every request in the API server log, and it includes the following attributes. apf_fs : the name of the flow schema to which the request was classified. apf_pl : the name of the priority level for that flow schema. apf_iseats : the number of seats determined for the initial (normal) stage of execution of the request. apf_fseats : the number of seats determined for the final stage of execution (accounting for the associated watch notifications) of the request. apf_additionalLatency : the duration of the final stage of execution of the request. At higher levels of verbosity there will be log lines exposing detail

s of how APF handled the request, primarily for debugging purposes. Response headers APF adds the following two headers to each HTTP response message. They won't appear in the audit log. They can be viewed from the client side. For client using klog, use verbosity -v=8 or higher to view these headers. X-Kubernetes-PF-FlowSchema-UID holds the UID of the FlowSchema object to which the corresponding request was classified. X-Kubernetes-PF-PriorityLevel-UID holds the UID of the PriorityLevelConfiguration object associated with that FlowSchema.

Field Description apiVersion stringeventratelimit.admission.k8s.io/v1alpha1 kind stringConfiguration limits [Required] []Limitlimits are the limits to place on event queries received. Limits can be placed on events received server-wide, per namespace, per user, and per source+object. At least one limit is required. Limit Appears in: Configuration Limit is the configuration for a particular limit type Field Description type [Required] LimitTypetype is the type of limit to which this configuration applies qps [Required] int32qps is the number of event queries per second that are allowed for this type of limit. The qps and burst fields are used together to determine if a particular event query is accepted. The qps determi

nes how many queries are accepted once the burst amount of queries has been exhausted. burst [Required] int32burst is the burst number of event queries that are allowed for this type of limit. The qps and burst fields are used together to determine if a particular event query is accepted. The burst determines the maximum size of the allowance granted for a particular bucket. For example, if the burst is 10 and the qps is 3, then the•

Field Description admission control will accept 10 queries before blocking any queries. Every second, 3 more queries will be allowed. If some of that allowance is not used, then it will roll over to the next second, until the maximum allowance of 10 is reached. cacheSize int32cacheSize is the size of the LRU cache for this type of limit. If a bucket is evicted from the cache, then the allowance for that bucket is reset. If more queries are later received for an evicted bucket, then that bucket will re-enter the cache with a clean slate, giving that bucket a full allowance of burst queries. The default cache size is 4096. If limitType is 'server', then cacheSize is ignored.

If this is specified and differs from the value in "kind", an equivalent match and conversion was performed. For example, if deployments can be modifi

ed via apps/v1 and apps/ v1beta1, and a webhook registered a rule of apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"] and matchPolicy: Equivalent , an API request to apps/v1beta1 deployments would be converted and sent to the webhook with kind: {group:"apps", version:"v1", kind:"Deployment"} (matching the rule the webhook registered for), and requestKind: {group:"apps", version:"v1beta1", kind:"Deployment"} (indicating the kind of the original API request). See documentation for the "matchPolicy" field in the webhook configuration type for more details. requestResource meta/ v1.GroupVersionResourceRequestResource is the fully-qualified resource of the original API request (for example, v1.pods). If this is specified and differs from the value in "resource", an equivalent match and conversion was performed. For example, if deployments can be modified via apps/v1 and apps/ v1beta1, and a webhook registered a rule of apiGroups:["apps"], apiVersions:["v1"], resour

ces: ["deployments"] and matchPolicy: Equivalent , an API request to apps/v1beta1 deployments would be converted and sent to the webhook with resource: {group:"apps", version:"v1", resource:"deployments"} (matching the resource the webhook registered for), and requestResource: {group:"apps", version:"v1beta1", resource:"deployments"} (indicating the resource of the original API request)

Field Description See documentation for the "matchPolicy" field in the webhook configuration type. requestSubResource stringRequestSubResource is the name of the subresource of the original API request, if any (for example, "status" or "scale") If this is specified and differs from the value in "subResource", an equivalent match and conversion was performed. See documentation for the "matchPolicy" field in the webhook configuration type. name stringName is the name of the object as presented in the request. On a CREATE operation, the client may omit name and rely on the server to generate the name. If that is the case, this field will contain an empty string. namespace stringNamespace is the namespace associated with the request (if any). operation [Required] OperationOperation is the operation being performed.

Defaults to false. options k8s.io/apimachinery/pkg/ runtime.RawExtensionOptions is the operation option structure of the operation being performed. e.g. meta.k8s.io/v1.DeleteOptions or meta.k8s.io/ v1.CreateOptions . This may be different than the options the caller provided. e.g. for a patch request the performed Operation might be a CREATE, in which case the Options will a meta.k8s.io/ v1.CreateOptions even though the caller provided meta.k8s.io/ v1.PatchOptions

AdmissionResponse Appears in: AdmissionReview AdmissionResponse describes an admission response. Field Description uid [Required] k8s.io/ apimachinery/pkg/ types.UIDUID is an identifier for the individual request/response. This must be copied over from the corresponding AdmissionRequest. allowed [Required] boolAllowed indicates whether or not the admission request was permitted. status meta/v1.StatusResult contains extra details into why an admission request was denied. This field IS NOT consulted in any way if "Allowed" is "true". patch []byteThe patch body. Currently we only support "JSONPatch" which implements RFC 6902. patchType PatchTypeThe type of Patch. Currently we only allow "JSONPatch". auditAnnotations map[string]stringAuditAnnotations is an unstructured key value map set by remote admission controller (e.g. error=image-blacklisted). MutatingAdmissionWebhook and ValidatingAdmissionWebhook admission controller will prefix the keys with admission webhook name (e.g. imagepoli

cy.example.com/error=image-blacklisted). AuditAnnotations will be provided by the admission webhook to add additional context to the audit log for this request. warnings []stringwarnings is a list of warning messages to return to the requesting API client. Warning messages describe a problem the client making the API request should correct or be aware of. Limit warnings to 120 characters if possible. Warnings over 256 characters and large numbers of warnings may be truncated. Operation (Alias of string ) Appears in: AdmissionRequest•

Note: All but the last IP can be arbitrarily set by the client. userAgent stringUserAgent records the user agent string reported by the client. Note that the UserAgent is provided by the client, and must not be trusted. objectRef ObjectReferenceObject reference this request is targeted at. Does not apply for List-type requests, or n

on-resource requests. responseStatus meta/v1.StatusThe response status, populated even when the ResponseObject is not a Status type. For successful responses, this will only include the Code and StatusSuccess. For non-status type error responses, this will be auto-populated with the error Message. requestObject k8s.io/apimachinery/pkg/ runtime.UnknownAPI object from the request, in JSON format. The RequestObject is recorded as-is in the request (possibly re-encoded as JSON), prior to version conversion, defaulting, admission or merging. It is an external versioned object type, and may not be a valid object on its own. Omitted for non-resource requests. Only logged at Request Level and higher. responseObject k8s.io/apimachinery/pkg/ runtime.UnknownAPI object returned in the response, in JSON. The ResponseObject is recorded after conversion to the external type, and serialized as JSON. Omitted for non-resource requests. Only logged at Response Level. requestReceivedTimestamp meta/v1.Micr

oTimeTime the request reached the apiserver.1. 2. 3

Field Description stageTimestamp meta/v1.MicroTimeTime the request reached current audit stage. annotations map[string]stringAnnotations is an unstructured key value map stored with an audit event that may be set by plugins invoked in the request serving chain, including authentication, authorization and admission plugins. Note that these annotations are for the audit event, and do not correspond to the metadata.annotations of the submitted object. Keys should uniquely identify the informing component to avoid name collisions (e.g. podsecuritypolicy.admission.k8s.io/policy). Values should be short. Annotations are included in the Metadata level. EventList EventList is a list of audit Events. Field Description apiVersion stringaudit.k8s.io/v1 kind stringEventList metadata meta/v1.ListMetaNo description provided. items [Required] []EventNo description provided. Policy Appears in: PolicyList Policy defines the configuration of audit logging, and the rules for how different request catego

ries are logged. Field Description apiVersion stringaudit.k8s.io/v1 kind stringPolicy metadata meta/ v1.ObjectMetaObjectMeta is included for interoperability with API infrastructure. Refer to the Kubernetes API documentation for the fields of the metadata field.

Field Description rules [Required] []PolicyRuleRules specify the audit Level a request should be recorded at. A request may match multiple rules, in which case the FIRST matching rule is used. The default audit level is None, but can be overridden by a catch-all rule at the end of the list. PolicyRules are strictly ordered. omitStages []StageOmitStages is a list of stages for which no events are created. Note that this can also be specified per rule in which case the union of both are omitted. omitManagedFields boolOmitManagedFields indicates whether to omit the managed fields of the request and response bodies from being written to the API audit log. This is used as a global default - a value of 'true' will omit the managed fileds, otherwise the managed fields will be included in the API audit log. Note that this can also be specified per rule in which case the value specified in a rule will override the global default. PolicyList PolicyList is a list of audit Policies. Field Descrip
