	SchemeBuilder = runtime.NewSchemeBuilder(addKnownTypes)
	AddToScheme   = SchemeBuilder.AddToScheme
)

Types

type Eviction

type Eviction struct {
	metav1.TypeMeta `json:",inline"`

	// ObjectMeta describes the pod that is being evicted.
	// +optional
	metav1.ObjectMeta `json:"metadata,omitempty" protobuf:"bytes,1,opt,name=metadata"`

	// DeleteOptions may be provided
	// +optional
	DeleteOptions *metav1.DeleteOptions `json:"deleteOptions,omitempty" protobuf:"bytes,2,opt,name=deleteOptions"`
}

Eviction evicts a pod from its node subject to certain policies and safety constraints. This is a subresource of Pod. A request to cause such an eviction is created by POSTing to .../pods/<pod name>/eviction.

type PodDisruptionBudget

type PodDisruptionBudget struct {
	metav1.TypeMeta `json:",inline"`
	// +optional
	metav1.ObjectMeta `json:"metadata,omitempty" protobuf:"bytes,1,opt,name=metadata"`

	// Specification of the desired behavior of the PodDisruptionBudget.
	// +optional
	Spec PodDisruptionBudgetSpec `json:"spec,omitempty" protobuf:"bytes,2,opt,name=spec"`
	// Most recently observed status of the PodDisruptionBudget.
	// +optional
	Status PodDisruptionBudgetStatus `json:"status,omitempty" protobuf:"bytes,3,opt,name=status"`
}

PodDisruptionBudget is an object to define the max disruption that can be caused to a collection of pods

type PodDisruptionBudgetList

type PodDisruptionBudgetList struct {
	metav1.TypeMeta `json:",inline"`
	// +optional
	metav1.ListMeta `json:"metadata,omitempty" protobuf:"bytes,1,opt,name=metadata"`
	Items           []PodDisruptionBudget `json:"items" protobuf:"bytes,2,rep,name=items"`
}

PodDisruptionBudgetList is a collection of PodDisruptionBudgets.

type PodDisruptionBudgetSpec

type PodDisruptionBudgetSpec struct {
	// An eviction is allowed if at least "minAvailable" pods selected by
	// "selector" will still be available after the eviction, i.e. even in the
	// absence of the evicted pod.  So for example you can prevent all voluntary
	// evictions by specifying "100%".
	// +optional
	MinAvailable intstr.IntOrString `json:"minAvailable,omitempty" protobuf:"bytes,1,opt,name=minAvailable"`

	// Label query over pods whose evictions are managed by the disruption
	// budget.
	// +optional
	Selector *metav1.LabelSelector `json:"selector,omitempty" protobuf:"bytes,2,opt,name=selector"`
}

PodDisruptionBudgetSpec is a description of a PodDisruptionBudget.

type PodDisruptionBudgetStatus

type PodDisruptionBudgetStatus struct {
	// Whether or not a disruption is currently allowed.
	PodDisruptionAllowed bool `json:"disruptionAllowed" protobuf:"varint,1,opt,name=disruptionAllowed"`

	// current number of healthy pods
	CurrentHealthy int32 `json:"currentHealthy" protobuf:"varint,2,opt,name=currentHealthy"`

	// minimum desired number of healthy pods
	DesiredHealthy int32 `json:"desiredHealthy" protobuf:"varint,3,opt,name=desiredHealthy"`

	// total number of pods counted by this disruption budget
	ExpectedPods int32 `json:"expectedPods" protobuf:"varint,4,opt,name=expectedPods"`
}

PodDisruptionBudgetStatus represents information about the status of a PodDisruptionBudget. Status may trail the actual state of a system.
