Functions ¶
func NewHandlerRunner ¶
func NewHandlerRunner(httpGetter kubetypes.HttpGetter, commandRunner kubecontainer.ContainerCommandRunner, containerManager podStatusProvider) kubecontainer.HandlerRunner
func NewPredicateAdmitHandler ¶ added in v1.5.0
func NewPredicateAdmitHandler(getNodeAnyWayFunc getNodeAnyWayFuncType, admissionFailureHandler AdmissionFailureHandler, pluginResourceUpdateFunc pluginResourceUpdateFuncType) *predicateAdmitHandler
Types ¶
type AdmissionFailureHandler ¶ added in v1.6.0
type AdmissionFailureHandler interface {
HandleAdmissionFailure(admitPod *v1.Pod, failureReasons []algorithm.PredicateFailureReason) (bool, []algorithm.PredicateFailureReason, error)
}
AdmissionFailureHandler is an interface which defines how to deal with a failure to admit a pod. This allows for the graceful handling of pod admission failure.
type AdmissionFailureHandlerStub ¶ added in v1.6.0
type AdmissionFailureHandlerStub struct{}
AdmissionFailureHandlerStub is an AdmissionFailureHandler that does not perform any handling of admission failure. It simply passes the failure on.
func NewAdmissionFailureHandlerStub ¶ added in v1.6.0
func NewAdmissionFailureHandlerStub() *AdmissionFailureHandlerStub
func (*AdmissionFailureHandlerStub) HandleAdmissionFailure ¶ added in v1.6.0
func (n *AdmissionFailureHandlerStub) HandleAdmissionFailure(admitPod *v1.Pod, failureReasons []algorithm.PredicateFailureReason) (bool, []algorithm.PredicateFailureReason, error)
type HandlerRunner ¶
type HandlerRunner struct {
// contains filtered or unexported fields
}
func (*HandlerRunner) Run ¶
func (hr *HandlerRunner) Run(containerID kubecontainer.ContainerID, pod *v1.Pod, container *v1.Container, handler *v1.Handler) (string, error)
type PodAdmitAttributes ¶ added in v1.3.0
type PodAdmitAttributes struct { // the pod to evaluate for admission Pod *v1.Pod // all pods bound to the kubelet excluding the pod being evaluated OtherPods []*v1.Pod }
PodAdmitAttributes is the context for a pod admission decision. The member fields of this struct should never be mutated.
type PodAdmitHandler ¶ added in v1.3.0
type PodAdmitHandler interface { // Admit evaluates if a pod can be admitted. Admit(attrs *PodAdmitAttributes) PodAdmitResult }
PodAdmitHandler is notified during pod admission.
func NewAppArmorAdmitHandler ¶ added in v1.4.0
func NewAppArmorAdmitHandler(validator apparmor.Validator) PodAdmitHandler
func NewNoNewPrivsAdmitHandler ¶ added in v1.8.0
func NewNoNewPrivsAdmitHandler(runtime kubecontainer.Runtime) PodAdmitHandler
func NewProcMountAdmitHandler ¶ added in v1.12.0
func NewProcMountAdmitHandler(runtime kubecontainer.Runtime) PodAdmitHandler
type PodAdmitHandlers ¶ added in v1.3.0
type PodAdmitHandlers []PodAdmitHandler
PodAdmitHandlers maintains a list of handlers to pod admission.
func (*PodAdmitHandlers) AddPodAdmitHandler ¶ added in v1.3.0
func (handlers *PodAdmitHandlers) AddPodAdmitHandler(a PodAdmitHandler)
AddPodAdmitHandler adds the specified observer.
type PodAdmitResult ¶ added in v1.3.0
type PodAdmitResult struct { // if true, the pod should be admitted. Admit bool // a brief single-word reason why the pod could not be admitted. Reason string // a brief message explaining why the pod could not be admitted. Message string }
PodAdmitResult provides the result of a pod admission decision.
type PodAdmitTarget ¶ added in v1.3.0
type PodAdmitTarget interface { // AddPodAdmitHandler adds the specified handler. AddPodAdmitHandler(a PodAdmitHandler) }
PodAdmitTarget maintains a list of handlers to invoke.
type PodLifecycleTarget ¶ added in v1.3.0
type PodLifecycleTarget interface { PodAdmitTarget PodSyncLoopTarget PodSyncTarget }
PodLifecycleTarget groups a set of lifecycle interfaces for convenience.
type PodSyncHandler ¶ added in v1.3.0
type PodSyncHandler interface { // ShouldEvict is invoked during each sync pod operation to determine // if the pod should be evicted from the kubelet. If so, the pod status // is updated to mark its phase as failed with the provided reason and message, // and the pod is immediately killed. // This operation must return immediately as its called for each sync pod. // The provided pod should never be modified. ShouldEvict(pod *v1.Pod) ShouldEvictResponse }
PodSyncHandler is invoked during each sync pod operation.
type PodSyncHandlers ¶ added in v1.3.0
type PodSyncHandlers []PodSyncHandler
PodSyncHandlers maintains a list of handlers to pod sync.
func (*PodSyncHandlers) AddPodSyncHandler ¶ added in v1.3.0
func (handlers *PodSyncHandlers) AddPodSyncHandler(a PodSyncHandler)
AddPodSyncHandler adds the specified handler.
type PodSyncLoopHandler ¶ added in v1.3.0
type PodSyncLoopHandler interface { // ShouldSync returns true if the pod needs to be synced. // This operation must return immediately as its called for each pod. // The provided pod should never be modified. ShouldSync(pod *v1.Pod) bool }
PodSyncLoopHandler is invoked during each sync loop iteration.
type PodSyncLoopHandlers ¶ added in v1.3.0
type PodSyncLoopHandlers []PodSyncLoopHandler
PodSyncLoopHandlers maintains a list of handlers to pod sync loop.
func (*PodSyncLoopHandlers) AddPodSyncLoopHandler ¶ added in v1.3.0
func (handlers *PodSyncLoopHandlers) AddPodSyncLoopHandler(a PodSyncLoopHandler)
AddPodSyncLoopHandler adds the specified observer.
type PodSyncLoopTarget ¶ added in v1.3.0
type PodSyncLoopTarget interface { // AddPodSyncLoopHandler adds the specified handler. AddPodSyncLoopHandler(a PodSyncLoopHandler) }
PodSyncLoopTarget maintains a list of handlers to pod sync loop.
type PodSyncTarget ¶ added in v1.3.0
type PodSyncTarget interface { // AddPodSyncHandler adds the specified handler AddPodSyncHandler(a PodSyncHandler) }
PodSyncTarget maintains a list of handlers to pod sync.
type ShouldEvictResponse ¶ added in v1.3.0
type ShouldEvictResponse struct { // if true, the pod should be evicted. Evict bool // a brief CamelCase reason why the pod should be evicted. Reason string // a brief message why the pod should be evicted. Message string }
ShouldEvictResponse provides the result of a should evict request.
