MutatingWebhook

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


FieldDescription
admissionReviewVersions *
string array
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
failurePolicy
string
failurePolicy defines how unrecognized errors from the admission endpoint are handled - allowed values are Ignore or Fail. Defaults to Fail.

Possible enum values:
- `"Fail"` means that an error calling the webhook causes the admission to fail.
- `"Ignore"` means that an error calling the webhook is ignored.
matchConditions
MatchCondition array
patch strategy: merge on key name
matchConditions is a list of conditions that must be met for a request to be sent to this webhook. 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. The exact matching logic is (in order): 1. If ANY matchCondition evaluates to FALSE, the webhook is skipped. 2. If ALL matchConditions evaluate to TRUE, the webhook is called. 3. If any matchCondition evaluates to an error (but none are FALSE): - If failurePolicy=Fail, reject the request - If failurePolicy=Ignore, the error is ignored and the webhook is skipped
matchPolicy
string
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"

Possible enum values:
- `"Equivalent"` means requests should be sent to the webhook if they modify a resource listed in rules via another API group or version.
- `"Exact"` means requests should only be sent to the webhook if they exactly match a given rule.
name *
string
name is 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.
namespaceSelector
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.
objectSelector
LabelSelector
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
string
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".

Possible enum values:
- `"IfNeeded"` indicates that the mutation may 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 mutation call.
- `"Never"` indicates that the mutation must not be called more than once in a single admission evaluation.
rules
RuleWithOperations array
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.
sideEffects *
string
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.

Possible enum values:
- `"None"` means that calling the webhook will have no side effects.
- `"NoneOnDryRun"` means that calling the webhook will possibly have side effects, but if the request being reviewed has the dry-run attribute, the side effects will be suppressed.
- `"Some"` means that calling the webhook will possibly have side effects. If a request with the dry-run attribute would trigger a call to this webhook, the request will instead fail.
- `"Unknown"` means that no information is known about the side effects of calling the webhook. If a request with the dry-run attribute would trigger a call to this webhook, the request will instead fail.
timeoutSeconds
integer
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.

Query Parameters

NameTypeDescription
pretty string If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun string When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

Path Parameters

NameTypeDescription
name string name of the MutatingWebhookConfiguration

Query Parameters

NameTypeDescription
pretty string If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun string When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
gracePeriodSeconds integer The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential boolean if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents boolean Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy string Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

delete Delete Collection

HTTP Request

DELETE /apis/admissionregistration.k8s.io/v1/mutatingwebhookconfigurations

Query Parameters

NameTypeDescription
pretty string If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue string The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun string When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector string A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds integer The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential boolean if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector string A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit integer limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents boolean Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy string Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion string resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch string resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents boolean `sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following:
- `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed.
- `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector string shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds integer Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

allowWatchBookmarks boolean allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue string The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize.

fieldSelector string A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector string A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit integer limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion string resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch string resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents boolean `sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection.

- `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector string shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds integer Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch boolean Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

Query Parameters

NameTypeDescription
allowWatchBookmarks boolean allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue string The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector string A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector string A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit integer limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty string If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion string resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch string resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents boolean `sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following:
- `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed.
- `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector string shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid").
