Chapter 6. ClusterVersion [config.openshift.io/v1] Description ClusterVersion is the configuration for the ClusterVersionOperator. This is where parameters related to automatic updates can be set. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). Type object Required spec 6.1. Specification Property Type Description apiVersion string 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: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources kind string 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: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds metadata ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata spec object spec is the desired state of the cluster version - the operator will work to ensure that the desired version is applied to the cluster. status object status contains information about the available updates and any in-progress updates. 6.1.1. .spec Description spec is the desired state of the cluster version - the operator will work to ensure that the desired version is applied to the cluster. Type object Required clusterID Property Type Description capabilities object capabilities configures the installation of optional, core cluster components. A null value here is identical to an empty object; see the child properties for default semantics. channel string channel is an identifier for explicitly requesting that a non-default set of updates be applied to this cluster. The default channel will be contain stable updates that are appropriate for production clusters. clusterID string clusterID uniquely identifies this cluster. This is expected to be an RFC4122 UUID value (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx in hexadecimal values). This is a required field. desiredUpdate object desiredUpdate is an optional field that indicates the desired value of the cluster version. Setting this value will trigger an upgrade (if the current version does not match the desired version). The set of recommended update values is listed as part of available updates in status, and setting values outside that range may cause the upgrade to fail. Some of the fields are inter-related with restrictions and meanings described here. 1. image is specified, version is specified, architecture is specified. API validation error. 2. image is specified, version is specified, architecture is not specified. You should not do this. version is silently ignored and image is used. 3. image is specified, version is not specified, architecture is specified. API validation error. 4. image is specified, version is not specified, architecture is not specified. image is used. 5. image is not specified, version is specified, architecture is specified. version and desired architecture are used to select an image. 6. image is not specified, version is specified, architecture is not specified. version and current architecture are used to select an image. 7. image is not specified, version is not specified, architecture is specified. API validation error. 8. image is not specified, version is not specified, architecture is not specified. API validation error. If an upgrade fails the operator will halt and report status about the failing component. Setting the desired update value back to the version will cause a rollback to be attempted. Not all rollbacks will succeed. overrides array overrides is list of overides for components that are managed by cluster version operator. Marking a component unmanaged will prevent the operator from creating or updating the object. overrides[] object ComponentOverride allows overriding cluster version operator's behavior for a component. upstream string upstream may be used to specify the preferred update server. By default it will use the appropriate update server for the cluster and region. 6.1.2. .spec.capabilities Description capabilities configures the installation of optional, core cluster components. A null value here is identical to an empty object; see the child properties for default semantics. Type object Property Type Description additionalEnabledCapabilities array (string) additionalEnabledCapabilities extends the set of managed capabilities beyond the baseline defined in baselineCapabilitySet. The default is an empty set. baselineCapabilitySet string baselineCapabilitySet selects an initial set of optional capabilities to enable, which can be extended via additionalEnabledCapabilities. If unset, the cluster will choose a default, and the default may change over time. The current default is vCurrent. 6.1.3. .spec.desiredUpdate Description desiredUpdate is an optional field that indicates the desired value of the cluster version. Setting this value will trigger an upgrade (if the current version does not match the desired version). The set of recommended update values is listed as part of available updates in status, and setting values outside that range may cause the upgrade to fail. Some of the fields are inter-related with restrictions and meanings described here. 1. image is specified, version is specified, architecture is specified. API validation error. 2. image is specified, version is specified, architecture is not specified. You should not do this. version is silently ignored and image is used. 3. image is specified, version is not specified, architecture is specified. API validation error. 4. image is specified, version is not specified, architecture is not specified. image is used. 5. image is not specified, version is specified, architecture is specified. version and desired architecture are used to select an image. 6. image is not specified, version is specified, architecture is not specified. version and current architecture are used to select an image. 7. image is not specified, version is not specified, architecture is specified. API validation error. 8. image is not specified, version is not specified, architecture is not specified. API validation error. If an upgrade fails the operator will halt and report status about the failing component. Setting the desired update value back to the version will cause a rollback to be attempted. Not all rollbacks will succeed. Type object Property Type Description architecture string architecture is an optional field that indicates the desired value of the cluster architecture. In this context cluster architecture means either a single architecture or a multi architecture. architecture can only be set to Multi thereby only allowing updates from single to multi architecture. If architecture is set, image cannot be set and version must be set. Valid values are 'Multi' and empty. force boolean force allows an administrator to update to an image that has failed verification or upgradeable checks. This option should only be used when the authenticity of the provided image has been verified out of band because the provided image will run with full administrative access to the cluster. Do not use this flag with images that comes from unknown or potentially malicious sources. image string image is a container image location that contains the update. image should be used when the desired version does not exist in availableUpdates or history. When image is set, version is ignored. When image is set, version should be empty. When image is set, architecture cannot be specified. version string version is a semantic version identifying the update version. version is ignored if image is specified and required if architecture is specified. 6.1.4. .spec.overrides Description overrides is list of overides for components that are managed by cluster version operator. Marking a component unmanaged will prevent the operator from creating or updating the object. Type array 6.1.5. .spec.overrides[] Description ComponentOverride allows overriding cluster version operator's behavior for a component. Type object Required group kind name namespace unmanaged Property Type Description group string group identifies the API group that the kind is in. kind string kind indentifies which object to override. name string name is the component's name. namespace string namespace is the component's namespace. If the resource is cluster scoped, the namespace should be empty. unmanaged boolean unmanaged controls if cluster version operator should stop managing the resources in this cluster. Default: false 6.1.6. .status Description status contains information about the available updates and any in-progress updates. Type object Required desired observedGeneration versionHash Property Type Description availableUpdates `` availableUpdates contains updates recommended for this cluster. Updates which appear in conditionalUpdates but not in availableUpdates may expose this cluster to known issues. This list may be empty if no updates are recommended, if the update service is unavailable, or if an invalid channel has been specified. capabilities object capabilities describes the state of optional, core cluster components. conditionalUpdates array conditionalUpdates contains the list of updates that may be recommended for this cluster if it meets specific required conditions. Consumers interested in the set of updates that are actually recommended for this cluster should use availableUpdates. This list may be empty if no updates are recommended, if the update service is unavailable, or if an empty or invalid channel has been specified. conditionalUpdates[] object ConditionalUpdate represents an update which is recommended to some clusters on the version the current cluster is reconciling, but which may not be recommended for the current cluster. conditions array conditions provides information about the cluster version. The condition "Available" is set to true if the desiredUpdate has been reached. The condition "Progressing" is set to true if an update is being applied. The condition "Degraded" is set to true if an update is currently blocked by a temporary or permanent error. Conditions are only valid for the current desiredUpdate when metadata.generation is equal to status.generation. conditions[] object ClusterOperatorStatusCondition represents the state of the operator's managed and monitored components. desired object desired is the version that the cluster is reconciling towards. If the cluster is not yet fully initialized desired will be set with the information available, which may be an image or a tag. history array history contains a list of the most recent versions applied to the cluster. This value may be empty during cluster startup, and then will be updated when a new update is being applied. The newest update is first in the list and it is ordered by recency. Updates in the history have state Completed if the rollout completed - if an update was failing or halfway applied the state will be Partial. Only a limited amount of update history is preserved. history[] object UpdateHistory is a single attempted update to the cluster. observedGeneration integer observedGeneration reports which version of the spec is being synced. If this value is not equal to metadata.generation, then the desired and conditions fields may represent a version. versionHash string versionHash is a fingerprint of the content that the cluster will be updated with. It is used by the operator to avoid unnecessary work and is for internal use only. 6.1.7. .status.capabilities Description capabilities describes the state of optional, core cluster components. Type object Property Type Description enabledCapabilities array (string) enabledCapabilities lists all the capabilities that are currently managed. knownCapabilities array (string) knownCapabilities lists all the capabilities known to the current cluster. 6.1.8. .status.conditionalUpdates Description conditionalUpdates contains the list of updates that may be recommended for this cluster if it meets specific required conditions. Consumers interested in the set of updates that are actually recommended for this cluster should use availableUpdates. This list may be empty if no updates are recommended, if the update service is unavailable, or if an empty or invalid channel has been specified. Type array 6.1.9. .status.conditionalUpdates[] Description ConditionalUpdate represents an update which is recommended to some clusters on the version the current cluster is reconciling, but which may not be recommended for the current cluster. Type object Required release risks Property Type Description conditions array conditions represents the observations of the conditional update's current status. Known types are: * Evaluating, for whether the cluster-version operator will attempt to evaluate any risks[].matchingRules. * Recommended, for whether the update is recommended for the current cluster. conditions[] object Condition contains details for one aspect of the current state of this API Resource. --- This struct is intended for direct use as an array at the field path .status.conditions. For example, type FooStatus struct{ // Represents the observations of a foo's current state. // Known .status.conditions.type are: "Available", "Progressing", and "Degraded" // +patchMergeKey=type // +patchStrategy=merge // +listType=map // +listMapKey=type Conditions []metav1.Condition json:"conditions,omitempty" patchStrategy:"merge" patchMergeKey:"type" protobuf:"bytes,1,rep,name=conditions" // other fields } release object release is the target of the update. risks array risks represents the range of issues associated with updating to the target release. The cluster-version operator will evaluate all entries, and only recommend the update if there is at least one entry and all entries recommend the update. risks[] object ConditionalUpdateRisk represents a reason and cluster-state for not recommending a conditional update. 6.1.10. .status.conditionalUpdates[].conditions Description conditions represents the observations of the conditional update's current status. Known types are: * Evaluating, for whether the cluster-version operator will attempt to evaluate any risks[].matchingRules. * Recommended, for whether the update is recommended for the current cluster. Type array 6.1.11. .status.conditionalUpdates[].conditions[] Description Condition contains details for one aspect of the current state of this API Resource. --- This struct is intended for direct use as an array at the field path .status.conditions. For example, type FooStatus struct{ // Represents the observations of a foo's current state. // Known .status.conditions.type are: "Available", "Progressing", and "Degraded" // +patchMergeKey=type // +patchStrategy=merge // +listType=map // +listMapKey=type Conditions []metav1.Condition json:"conditions,omitempty" patchStrategy:"merge" patchMergeKey:"type" protobuf:"bytes,1,rep,name=conditions" // other fields } Type object Required lastTransitionTime message reason status type Property Type Description lastTransitionTime string lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable. message string message is a human readable message indicating details about the transition. This may be an empty string. observedGeneration integer observedGeneration represents the .metadata.generation that the condition was set based upon. For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date with respect to the current state of the instance. reason string reason contains a programmatic identifier indicating the reason for the condition's last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty. status string status of the condition, one of True, False, Unknown. type string type of condition in CamelCase or in foo.example.com/CamelCase. --- Many .condition.type values are consistent across resources like Available, but because arbitrary conditions can be useful (see .node.status.conditions), the ability to deconflict is important. The regex it matches is (dns1123SubdomainFmt/)?(qualifiedNameFmt) 6.1.12. .status.conditionalUpdates[].release Description release is the target of the update. Type object Property Type Description channels array (string) channels is the set of Cincinnati channels to which the release currently belongs. image string image is a container image location that contains the update. When this field is part of spec, image is optional if version is specified and the availableUpdates field contains a matching version. url string url contains information about this release. This URL is set by the 'url' metadata property on a release or the metadata returned by the update API and should be displayed as a link in user interfaces. The URL field may not be set for test or nightly releases. version string version is a semantic version identifying the update version. When this field is part of spec, version is optional if image is specified. 6.1.13. .status.conditionalUpdates[].risks Description risks represents the range of issues associated with updating to the target release. The cluster-version operator will evaluate all entries, and only recommend the update if there is at least one entry and all entries recommend the update. Type array 6.1.14. .status.conditionalUpdates[].risks[] Description ConditionalUpdateRisk represents a reason and cluster-state for not recommending a conditional update. Type object Required matchingRules message name url Property Type Description matchingRules array matchingRules is a slice of conditions for deciding which clusters match the risk and which do not. The slice is ordered by decreasing precedence. The cluster-version operator will walk the slice in order, and stop after the first it can successfully evaluate. If no condition can be successfully evaluated, the update will not be recommended. matchingRules[] object ClusterCondition is a union of typed cluster conditions. The 'type' property determines which of the type-specific properties are relevant. When evaluated on a cluster, the condition may match, not match, or fail to evaluate. message string message provides additional information about the risk of updating, in the event that matchingRules match the cluster state. This is only to be consumed by humans. It may contain Line Feed characters (U+000A), which should be rendered as new lines. name string name is the CamelCase reason for not recommending a conditional update, in the event that matchingRules match the cluster state. url string url contains information about this risk. 6.1.15. .status.conditionalUpdates[].risks[].matchingRules Description matchingRules is a slice of conditions for deciding which clusters match the risk and which do not. The slice is ordered by decreasing precedence. The cluster-version operator will walk the slice in order, and stop after the first it can successfully evaluate. If no condition can be successfully evaluated, the update will not be recommended. Type array 6.1.16. .status.conditionalUpdates[].risks[].matchingRules[] Description ClusterCondition is a union of typed cluster conditions. The 'type' property determines which of the type-specific properties are relevant. When evaluated on a cluster, the condition may match, not match, or fail to evaluate. Type object Required type Property Type Description promql object promQL represents a cluster condition based on PromQL. type string type represents the cluster-condition type. This defines the members and semantics of any additional properties. 6.1.17. .status.conditionalUpdates[].risks[].matchingRules[].promql Description promQL represents a cluster condition based on PromQL. Type object Required promql Property Type Description promql string PromQL is a PromQL query classifying clusters. This query query should return a 1 in the match case and a 0 in the does-not-match case. Queries which return no time series, or which return values besides 0 or 1, are evaluation failures. 6.1.18. .status.conditions Description conditions provides information about the cluster version. The condition "Available" is set to true if the desiredUpdate has been reached. The condition "Progressing" is set to true if an update is being applied. The condition "Degraded" is set to true if an update is currently blocked by a temporary or permanent error. Conditions are only valid for the current desiredUpdate when metadata.generation is equal to status.generation. Type array 6.1.19. .status.conditions[] Description ClusterOperatorStatusCondition represents the state of the operator's managed and monitored components. Type object Required lastTransitionTime status type Property Type Description lastTransitionTime string lastTransitionTime is the time of the last update to the current status property. message string message provides additional information about the current condition. This is only to be consumed by humans. It may contain Line Feed characters (U+000A), which should be rendered as new lines. reason string reason is the CamelCase reason for the condition's current status. status string status of the condition, one of True, False, Unknown. type string type specifies the aspect reported by this condition. 6.1.20. .status.desired Description desired is the version that the cluster is reconciling towards. If the cluster is not yet fully initialized desired will be set with the information available, which may be an image or a tag. Type object Property Type Description channels array (string) channels is the set of Cincinnati channels to which the release currently belongs. image string image is a container image location that contains the update. When this field is part of spec, image is optional if version is specified and the availableUpdates field contains a matching version. url string url contains information about this release. This URL is set by the 'url' metadata property on a release or the metadata returned by the update API and should be displayed as a link in user interfaces. The URL field may not be set for test or nightly releases. version string version is a semantic version identifying the update version. When this field is part of spec, version is optional if image is specified. 6.1.21. .status.history Description history contains a list of the most recent versions applied to the cluster. This value may be empty during cluster startup, and then will be updated when a new update is being applied. The newest update is first in the list and it is ordered by recency. Updates in the history have state Completed if the rollout completed - if an update was failing or halfway applied the state will be Partial. Only a limited amount of update history is preserved. Type array 6.1.22. .status.history[] Description UpdateHistory is a single attempted update to the cluster. Type object Required image startedTime state verified Property Type Description acceptedRisks string acceptedRisks records risks which were accepted to initiate the update. For example, it may menition an Upgradeable=False or missing signature that was overriden via desiredUpdate.force, or an update that was initiated despite not being in the availableUpdates set of recommended update targets. completionTime `` completionTime, if set, is when the update was fully applied. The update that is currently being applied will have a null completion time. Completion time will always be set for entries that are not the current update (usually to the started time of the update). image string image is a container image location that contains the update. This value is always populated. startedTime string startedTime is the time at which the update was started. state string state reflects whether the update was fully applied. The Partial state indicates the update is not fully applied, while the Completed state indicates the update was successfully rolled out at least once (all parts of the update successfully applied). verified boolean verified indicates whether the provided update was properly verified before it was installed. If this is false the cluster may not be trusted. Verified does not cover upgradeable checks that depend on the cluster state at the time when the update target was accepted. version string version is a semantic version identifying the update version. If the requested image does not define a version, or if a failure occurs retrieving the image, this value may be empty. 6.2. API endpoints The following API endpoints are available: /apis/config.openshift.io/v1/clusterversions DELETE : delete collection of ClusterVersion GET : list objects of kind ClusterVersion POST : create a ClusterVersion /apis/config.openshift.io/v1/clusterversions/{name} DELETE : delete a ClusterVersion GET : read the specified ClusterVersion PATCH : partially update the specified ClusterVersion PUT : replace the specified ClusterVersion /apis/config.openshift.io/v1/clusterversions/{name}/status GET : read status of the specified ClusterVersion PATCH : partially update status of the specified ClusterVersion PUT : replace status of the specified ClusterVersion 6.2.1. /apis/config.openshift.io/v1/clusterversions Table 6.1. Global query parameters Parameter Type Description pretty string If 'true', then the output is pretty printed. HTTP method DELETE Description delete collection of ClusterVersion Table 6.2. Query parameters Parameter Type Description 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 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 key, but from the latest snapshot, which is inconsistent from the 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 " 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 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. 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. 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. Table 6.3. HTTP responses HTTP code Reponse body 200 - OK Status schema 401 - Unauthorized Empty HTTP method GET Description list objects of kind ClusterVersion Table 6.4.

Query parameters Parameter Type Description 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 fieldManager string fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint . fieldValidation string fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. 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. Table 6.7. Body parameters Parameter Type Description body ClusterVersion schema Table 6.8.

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. 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.

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. force boolean Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests. Table 6.17.
