Constants

const (

	// CreatPodTimeout sets maximum time from the moment a pod is added to CreatePods in WorkloadSpread.Status by webhook
	// to the time when the pod is expected to be seen by controller. If the pod has not been found by controller
	// during that time it is assumed, which means it won't be created at all and corresponding record in map can be
	// removed from WorkloadSpread.Status. It is assumed that pod/ws apiserver to controller latency is relatively small (like 1-2sec)
	// so the below value should be more enough.
	CreatPodTimeout = 30 * time.Second

func GetWorkloadSpreadSubsetCondition

func GetWorkloadSpreadSubsetCondition(status *appsv1alpha1.WorkloadSpreadSubsetStatus, condType appsv1alpha1.WorkloadSpreadSubsetConditionType) *appsv1alpha1.WorkloadSpreadSubsetCondition

GetWorkloadSpreadSubsetCondition returns the condition with the provided type.

func NewWorkloadSpreadSubsetCondition

func NewWorkloadSpreadSubsetCondition(condType appsv1alpha1.WorkloadSpreadSubsetConditionType, status corev1.ConditionStatus, reason, message string) *appsv1alpha1.WorkloadSpreadSubsetCondition

NewWorkloadSpreadSubsetCondition creates a new WorkloadSpreadSubset condition.

func PodUnscheduledTimeout

func PodUnscheduledTimeout(ws *appsv1alpha1.WorkloadSpread, pod *corev1.Pod) bool

PodUnscheduledTimeout return true when Pod was scheduled failed and timeout.

Types

type EventAction

type EventAction string

)

type ReconcileWorkloadSpread

type ReconcileWorkloadSpread struct {
	client.Client
	// contains filtered or unexported fields
}
