PodGroup represents a runtime instance of pods grouped together. PodGroups are created by workload controllers (Job, LWS, JobSet, etc...) from Workload.podGroupTemplates. PodGroup API enablement is toggled by the GenericWorkload feature gate.
apiVersionstring = "scheduling.k8s.io/v1alpha2"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#resourceskindstring = "PodGroup"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-kindsmetadataObjectMetaStandard object's metadata.More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
annotationsmap[string]stringAnnotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects.More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/annotationscreationTimestampTime read-onlyCreationTimestamp is a timestamp representing the server time when this object was created. It is not guaranteed to be set in happens-before order across separate operations. Clients may not set this value. It is represented in RFC3339 form and is in UTC.Populated by the system.Read-only. Null for lists.More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadatadeletionGracePeriodSecondsinteger (int64) read-onlyNumber of seconds allowed for this object to gracefully terminate before it will be removed from the system. Only set when deletionTimestamp is also set. May only be shortened.Read-only.deletionTimestampTime read-onlyDeletionTimestamp is RFC 3339 date and time at which this resource will be deleted. This field is set by the server when a graceful deletion is requested by the user, and is not directly settable by a client. The resource is expected to be deleted (no longer visible from resource lists, and not reachable by name) after the time in this field, once the finalizers list is empty. As long as the finalizers list contains items, deletion is blocked. Once the deletionTimestamp is set, this value may not be unset or be set further into the future, although it may be shortened or the resource may be deleted prior to this time. For example, a user may request that a pod is deleted in 30 seconds. The Kubelet will react by sending a graceful termination signal to the containers in the pod. After that 30 seconds, the Kubelet will send a hard termination signal (SIGKILL) to the container and after cleanup, remove the pod from the API. In the presence of network partitions, this object may still exist after this timestamp, until an administrator or automated process can determine the resource is fully terminated. If not set, graceful deletion of the object has not been requested.Populated by the system when a graceful deletion is requested.Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadatafinalizers[]stringMust be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed. Finalizers may be processed and removed in any order. Order is NOT enforced because it introduces significant risk of stuck finalizers. finalizers is a shared field, any actor with permission can reorder it. If the finalizer list is processed in order, then this can lead to a situation in which the component responsible for the first finalizer in the list is waiting for a signal (field value, external system, or other) produced by a component responsible for a finalizer later in the list, resulting in a deadlock. Without enforced ordering finalizers are free to order amongst themselves and are not vulnerable to ordering changes in the list.generateNamestringGenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided. If this field is used, the name returned to the client will be different than the name passed. This value will also be combined with a unique suffix. The provided value has the same validation rules as the Name field, and may be truncated by the length of the suffix required to make the value unique on the server.If this field is specified and the generated name exists, the server will return a 409.Applied only if Name is not specified.More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#idempotencygenerationinteger (int64) read-onlyA sequence number representing a specific generation of the desired state.Populated by the system.Read-only.labelsmap[string]stringMap of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services.More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labelsmanagedFields[]ManagedFieldsEntryManagedFields maps workflow-id and version to the set of fields that are managed by that workflow. This is mostly for internal housekeeping, and users typically shouldn't need to set or understand this field. A workflow can be the user's name, a controller's name, or the name of a specific apply path like "ci-cd". The set of fields is always in the version that the workflow used when modifying the object.
apiVersionstringAPIVersion defines the version of this resource that this field set applies to. The format is "group/version" just like the top-level APIVersion field. It is necessary to track the version of a field set because it cannot be automatically converted.fieldsTypestringFieldsType is the discriminator for the different fields format and version. There is currently only one possible value: "FieldsV1"fieldsV1FieldsV1FieldsV1 holds the first JSON version format as described in the "FieldsV1" type.managerstringManager is an identifier of the workflow managing these fields.operationstringOperation is the type of operation which lead to this ManagedFieldsEntry being created. The only valid values for this field are 'Apply' and 'Update'.subresourcestringSubresource is the name of the subresource used to update that object, or empty string if the object was updated through the main resource. The value of this field is used to distinguish between managers, even if they share the same name. For example, a status update will be distinct from a regular update using the same manager name. Note that the APIVersion field is not related to the Subresource field and it always corresponds to the version of the main resource.timeTimeTime is the timestamp of when the ManagedFields entry was added. The timestamp will also be updated if a field is added, the manager changes any of the owned fields value or removes a field. The timestamp does not update when a field is removed from the entry because another manager took it over.namestringName must be unique within a namespace. Is required when creating resources, although some resources may allow a client to request the generation of an appropriate name automatically. Name is primarily intended for creation idempotence and configuration definition.Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#namesnamespacestringNamespace defines the space within which each name must be unique. An empty namespace is equivalent to the "default" namespace, but "default" is the canonical representation. Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty.Must be a DNS_LABEL.Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespacesownerReferences[]OwnerReferenceList of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.
apiVersionstring requiredAPI version of the referent.blockOwnerDeletionbooleanIf true, AND if the owner has the "foregroundDeletion" finalizer, then the owner cannot be deleted from the key-value store until this reference is removed. See https://kubernetes.io/docs/concepts/architecture/garbage-collection/#foreground-deletion for how the garbage collector interacts with this field and enforces the foreground deletion. Defaults to false. To set this field, a user needs "delete" permission of the owner, otherwise 422 (Unprocessable Entity) will be returned.controllerbooleanIf true, this reference points to the managing controller.kindstring requiredKind of the referent.More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kindsnamestring requiredName of the referent.More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#namesuidstring requiredUID of the referent.More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uidsresourceVersionstring read-onlyAn opaque value that represents the internal version of this object that can be used by clients to determine when objects have changed. May be used for optimistic concurrency, change detection, and the watch operation on a resource or set of resources. Clients must treat these values as opaque and passed unmodified back to the server. They may only be valid for a particular resource or set of resources.Populated by the system.Read-only. Value must be treated as opaque by clients and .More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistencyselfLinkstring read-onlyDeprecated: selfLink is a legacy read-only field that is no longer populated by the system.uidstring read-onlyUID is the unique in time and space value for this object. It is typically generated by the server on successful creation of a resource and is not allowed to change on PUT operations.Populated by the system.Read-only. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uidsspecPodGroupSpec requiredSpec defines the desired state of the PodGroup.
disruptionModestringDisruptionMode defines the mode in which a given PodGroup can be disrupted. Controllers are expected to fill this field by copying it from a PodGroupTemplate. One of Pod, PodGroup. Defaults to Pod if unset. This field is immutable. This field is available only when the WorkloadAwarePreemption feature gate is enabled.podGroupTemplateRefPodGroupTemplateReferencePodGroupTemplateRef references an optional PodGroup template within other object (e.g. Workload) that was used to create the PodGroup. This field is immutable.
workloadWorkloadPodGroupTemplateReferenceWorkload references the PodGroupTemplate within the Workload object that was used to create the PodGroup.
podGroupTemplateNamestring requiredPodGroupTemplateName defines the PodGroupTemplate name within the Workload object.workloadNamestring requiredWorkloadName defines the name of the Workload object.priorityinteger (int32)Priority is the value of priority of this pod group. Various system components use this field to find the priority of the pod group. When Priority Admission Controller is enabled, it prevents users from setting this field. The admission controller populates this field from PriorityClassName. The higher the value, the higher the priority. This field is immutable. This field is available only when the WorkloadAwarePreemption feature gate is enabled.priorityClassNamestringPriorityClassName defines the priority that should be considered when scheduling this pod group. Controllers are expected to fill this field by copying it from a PodGroupTemplate. Otherwise, it is validated and resolved similarly to the PriorityClassName on PodGroupTemplate (i.e. if no priority class is specified, admission control can set this to the global default priority class if it exists. Otherwise, the pod group's priority will be zero). This field is immutable. This field is available only when the WorkloadAwarePreemption feature gate is enabled.resourceClaims[]PodGroupResourceClaimResourceClaims defines which ResourceClaims may be shared among Pods in the group. Pods consume the devices allocated to a PodGroup's claim by defining a claim in its own Spec.ResourceClaims that matches the PodGroup's claim exactly. The claim must have the same name and refer to the same ResourceClaim or ResourceClaimTemplate.This is an alpha-level field and requires that the DRAWorkloadResourceClaims feature gate is enabled.This field is immutable.
namestring requiredName uniquely identifies this resource claim inside the PodGroup. This must be a DNS_LABEL.resourceClaimNamestringResourceClaimName is the name of a ResourceClaim object in the same namespace as this PodGroup. The ResourceClaim will be reserved for the PodGroup instead of its individual pods.Exactly one of ResourceClaimName and ResourceClaimTemplateName must be set.resourceClaimTemplateNamestringResourceClaimTemplateName is the name of a ResourceClaimTemplate object in the same namespace as this PodGroup.The template will be used to create a new ResourceClaim, which will be bound to this PodGroup. When this PodGroup is deleted, the ResourceClaim will also be deleted. The PodGroup name and resource name, along with a generated component, will be used to form a unique name for the ResourceClaim, which will be recorded in podgroup.status.resourceClaimStatuses.This field is immutable and no changes will be made to the corresponding ResourceClaim by the control plane after creating the ResourceClaim.Exactly one of ResourceClaimName and ResourceClaimTemplateName must be set.schedulingConstraintsPodGroupSchedulingConstraintsSchedulingConstraints defines optional scheduling constraints (e.g. topology) for this PodGroup. Controllers are expected to fill this field by copying it from a PodGroupTemplate. This field is immutable. This field is only available when the TopologyAwareWorkloadScheduling feature gate is enabled.
topology[]TopologyConstraintTopology defines the topology constraints for the pod group. Currently only a single topology constraint can be specified. This may change in the future.
keystring requiredKey specifies the key of the node label representing the topology domain. All pods within the PodGroup must be colocated within the same domain instance. Different PodGroups can land on different domain instances even if they derive from the same PodGroupTemplate. Examples: "topology.kubernetes.io/rack"schedulingPolicyPodGroupSchedulingPolicy requiredSchedulingPolicy defines the scheduling policy for this instance of the PodGroup. Controllers are expected to fill this field by copying it from a PodGroupTemplate. This field is immutable.
basicBasicSchedulingPolicyBasic specifies that the pods in this group should be scheduled using standard Kubernetes scheduling behavior.gangGangSchedulingPolicyGang specifies that the pods in this group should be scheduled using all-or-nothing semantics.
minCountinteger (int32) requiredMinCount is the minimum number of pods that must be schedulable or scheduled at the same time for the scheduler to admit the entire group. It must be a positive integer.statusPodGroupStatus read-onlyStatus represents the current observed state of the PodGroup.
conditions[]Condition read-onlyConditions represent the latest observations of the PodGroup's state.Known condition types: - "PodGroupScheduled": Indicates whether the scheduling requirement has been satisfied. - "DisruptionTarget": Indicates whether the PodGroup is about to be terminated due to disruption such as preemption.Known reasons for the PodGroupScheduled condition: - "Unschedulable": The PodGroup cannot be scheduled due to resource constraints, affinity/anti-affinity rules, or insufficient capacity for the gang.- "SchedulerError": The PodGroup cannot be scheduled due to some internal error
that happened during scheduling, for example due to nodeAffinity parsing errors.Known reasons for the DisruptionTarget condition: - "PreemptionByScheduler": The PodGroup was preempted by the scheduler to make room for higher-priority PodGroups or Pods.
lastTransitionTimeTime required read-onlylastTransitionTime 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.messagestring required read-onlymessage is a human readable message indicating details about the transition. This may be an empty string.observedGenerationinteger (int64) read-onlyobservedGeneration 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.reasonstring required read-onlyreason 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.statusstring required read-onlystatus of the condition, one of True, False, Unknown.typestring required read-onlytype of condition in CamelCase or in foo.example.com/CamelCase.resourceClaimStatuses[]PodGroupResourceClaimStatus read-onlyStatus of resource claims.
namestring required read-onlyName uniquely identifies this resource claim inside the PodGroup. This must match the name of an entry in podgroup.spec.resourceClaims, which implies that the string must be a DNS_LABEL.resourceClaimNamestring read-onlyResourceClaimName is the name of the ResourceClaim that was generated for the PodGroup in the namespace of the PodGroup. If this is unset, then generating a ResourceClaim was not necessary. The podgroup.spec.resourceClaims entry can be ignored in this case.
