Types

type ControllerRevision added in v1.7.0 

type ControllerRevision struct {
	metav1.TypeMeta
	// Standard object's metadata.
	// More info: https://git.k8s.io/community/contributors/devel/api-conventions.md#metadata
	// +optional
	metav1.ObjectMeta

	// Data is the Object representing the state.
	Data runtime.Object

	// Revision indicates the revision of the state represented by Data.
	Revision int64
}

ControllerRevision implements an immutable snapshot of state data. Clients are responsible for serializing and deserializing the objects that contain their internal state. Once a ControllerRevision has been successfully created, it can not be updated. The API Server will fail validation of all requests that attempt to mutate the Data field. ControllerRevisions may, however, be deleted.

type ControllerRevisionList added in v1.7.0 

type ControllerRevisionList struct {
	metav1.TypeMeta
	// +optional
	metav1.ListMeta

	// Items is the list of ControllerRevision objects.
	Items []ControllerRevision
}

ControllerRevisionList is a resource containing a list of ControllerRevision objects.

type PodManagementPolicyType added in v1.7.0 

type PodManagementPolicyType string

PodManagementPolicyType defines the policy for creating pods under a stateful set. 

const (
	// OrderedReadyPodManagement will create pods in strictly increasing order on
	// scale up and strictly decreasing order on scale down, progressing only when
	// the previous pod is ready or terminated. At most one pod will be changed
	// at any time.
	OrderedReadyPodManagement PodManagementPolicyType = "OrderedReady"
	// ParallelPodManagement will create and delete pods as soon as the stateful set
	// replica count is changed, and will not wait for pods to be ready or complete
	// termination.
	ParallelPodManagement = "Parallel"
)

type RollingUpdateStatefulSetStrategy added in v1.7.0 

type RollingUpdateStatefulSetStrategy struct {
	// Partition indicates the ordinal at which the StatefulSet should be
	// partitioned.
	Partition int32
}

RollingUpdateStatefulSetStrategy is used to communicate parameter for RollingUpdateStatefulSetStrategyType.

type StatefulSet 

type StatefulSet struct {
	metav1.TypeMeta
	// +optional
	metav1.ObjectMeta

	// Spec defines the desired identities of pods in this set.
	// +optional
	Spec StatefulSetSpec

	// Status is the current status of Pods in this StatefulSet. This data
	// may be out of date by some window of time.
	// +optional
	Status StatefulSetStatus
}

StatefulSet represents a set of pods with consistent identities. Identities are defined as:

  • Network: A single stable DNS and hostname.
  • Storage: As many VolumeClaims as requested.

The StatefulSet guarantees that a given network identity will always map to the same storage identity.

type StatefulSetList 

type StatefulSetList struct {
	metav1.TypeMeta
	// +optional
	metav1.ListMeta
	Items []StatefulSet
}

StatefulSetList is a collection of StatefulSets.

type StatefulSetSpec 

type StatefulSetSpec struct {
	// Replicas is the desired number of replicas of the given Template.
	// These are replicas in the sense that they are instantiations of the
	// same Template, but individual replicas also have a consistent identity.
	// If unspecified, defaults to 1.
	// TODO: Consider a rename of this field.
	// +optional
	Replicas int32

	// Selector is a label query over pods that should match the replica count.
	// If empty, defaulted to labels on the pod template.
	// More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors
	// +optional
	Selector *metav1.LabelSelector

	// Template is the object that describes the pod that will be created if
	// insufficient replicas are detected. Each pod stamped out by the StatefulSet
	// will fulfill this Template, but have a unique identity from the rest
	// of the StatefulSet.
	Template api.PodTemplateSpec

	// VolumeClaimTemplates is a list of claims that pods are allowed to reference.
	// The StatefulSet controller is responsible for mapping network identities to
	// claims in a way that maintains the identity of a pod. Every claim in
	// this list must have at least one matching (by name) volumeMount in one
	// container in the template. A claim in this list takes precedence over
	// any volumes in the template, with the same name.
	// TODO: Define the behavior if a claim already exists with the same name.
	// +optional
	VolumeClaimTemplates []api.PersistentVolumeClaim

	// ServiceName is the name of the service that governs this StatefulSet.
	// This service must exist before the StatefulSet, and is responsible for
	// the network identity of the set. Pods get DNS/hostnames that follow the
	// pattern: pod-specific-string.serviceName.default.svc.cluster.local
	// where "pod-specific-string" is managed by the StatefulSet controller.
	ServiceName string

	// PodManagementPolicy controls how pods are created during initial scale up,
	// when replacing pods on nodes, or when scaling down. The default policy is
	// `OrderedReady`, where pods are created in increasing order (pod-0, then
	// pod-1, etc) and the controller will wait until each pod is ready before
	// continuing. When scaling down, the pods are removed in the opposite order.
	// The alternative policy is `Parallel` which will create pods in parallel
	// to match the desired scale without waiting, and on scale down will delete
	// all pods at once.
	// +optional
	PodManagementPolicy PodManagementPolicyType

	// updateStrategy indicates the StatefulSetUpdateStrategy that will be
	// employed to update Pods in the StatefulSet when a revision is made to
	// Template.
	UpdateStrategy StatefulSetUpdateStrategy

	// revisionHistoryLimit is the maximum number of revisions that will
	// be maintained in the StatefulSet's revision history. The revision history
	// consists of all revisions not represented by a currently applied
	// StatefulSetSpec version. The default value is 10.
	RevisionHistoryLimit *int32
}

A StatefulSetSpec is the specification of a StatefulSet.

type StatefulSetStatus 

type StatefulSetStatus struct {
	// observedGeneration is the most recent generation observed for this StatefulSet. It corresponds to the
	// StatefulSet's generation, which is updated on mutation by the API Server.
	// +optional
	ObservedGeneration *int64

	// replicas is the number of Pods created by the StatefulSet controller.
	Replicas int32

	// readyReplicas is the number of Pods created by the StatefulSet controller that have a Ready Condition.
	ReadyReplicas int32

	// currentReplicas is the number of Pods created by the StatefulSet controller from the StatefulSet version
	// indicated by currentRevision.
	CurrentReplicas int32

	// updatedReplicas is the number of Pods created by the StatefulSet controller from the StatefulSet version
	// indicated by updateRevision.
	UpdatedReplicas int32

	// currentRevision, if not empty, indicates the version of the StatefulSet used to generate Pods in the
	// sequence [0,currentReplicas).
	CurrentRevision string

	// updateRevision, if not empty, indicates the version of the StatefulSet used to generate Pods in the sequence
	// [replicas-updatedReplicas,replicas)
	UpdateRevision string
}

StatefulSetStatus represents the current state of a StatefulSet.

type StatefulSetUpdateStrategy added in v1.7.0 

type StatefulSetUpdateStrategy struct {
	// Type indicates the type of the StatefulSetUpdateStrategy.
	Type StatefulSetUpdateStrategyType
	// RollingUpdate is used to communicate parameters when Type is RollingUpdateStatefulSetStrategyType.
	RollingUpdate *RollingUpdateStatefulSetStrategy
}

StatefulSetUpdateStrategy indicates the strategy that the StatefulSet controller will use to perform updates. It includes any additional parameters necessary to perform the update for the indicated strategy.

type StatefulSetUpdateStrategyType added in v1.7.0 

type StatefulSetUpdateStrategyType string

StatefulSetUpdateStrategyType is a string enumeration type that enumerates all possible update strategies for the StatefulSet controller.
