Functions

func Int32 

func Int32(v int32) *int32

Int32 is a helper routine that allocates a new int32 value to store v and returns a pointer to it.

func IsChieforMaster 

func IsChieforMaster(typ TFReplicaType) bool

IsChieforMaster returns true if the type is Master or Chief.

func IsEvaluator 

func IsEvaluator(typ TFReplicaType) bool

IsEvaluator returns true if the type is Evaluator.

func IsWorker 

func IsWorker(typ TFReplicaType) bool

IsWorker returns true if the type is Worker.

func RegisterDefaults 

func RegisterDefaults(scheme *runtime.Scheme) error

RegisterDefaults adds defaulters functions to the given scheme. Public to allow building arbitrary schemes. All generated defaulters are covering - they call all nested defaulters.

func Resource 

func Resource(resource string) schema.GroupResource

Resource takes an unqualified resource and returns a Group-qualified GroupResource.

func SetDefaults_TFJob 

func SetDefaults_TFJob(tfjob *TFJob)

SetDefaults_TFJob sets any unspecified values to defaults.

func SetObjectDefaults_TFJob 

func SetObjectDefaults_TFJob(in *TFJob)

func SetObjectDefaults_TFJobList 

func SetObjectDefaults_TFJobList(in *TFJobList)

Types

type TFJob 

type TFJob struct {
	// Standard Kubernetes type metadata.
	metav1.TypeMeta `json:",inline"`

	// Standard Kubernetes object's metadata.
	metav1.ObjectMeta `json:"metadata,omitempty"`

	// Specification of the desired state of the TFJob.
	Spec TFJobSpec `json:"spec,omitempty"`

	// Most recently observed status of the TFJob.
	// Read-only (modified by the system).
	Status common.JobStatus `json:"status,omitempty"`
}

Represents a TFJob resource.

func (*TFJob) DeepCopy 

func (in *TFJob) DeepCopy() *TFJob

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new TFJob.

func (*TFJob) DeepCopyInto 

func (in *TFJob) DeepCopyInto(out *TFJob)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

func (*TFJob) DeepCopyObject 

func (in *TFJob) DeepCopyObject() runtime.Object

DeepCopyObject is an autogenerated deepcopy function, copying the receiver, creating a new runtime.Object.

type TFJobList 

type TFJobList struct {
	// Standard type metadata.
	metav1.TypeMeta `json:",inline"`

	// Standard list metadata.
	metav1.ListMeta `json:"metadata,omitempty"`

	// List of TFJobs.
	Items []TFJob `json:"items"`
}

TFJobList is a list of TFJobs.

func (*TFJobList) DeepCopy 

func (in *TFJobList) DeepCopy() *TFJobList

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new TFJobList.

func (*TFJobList) DeepCopyInto 

func (in *TFJobList) DeepCopyInto(out *TFJobList)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

func (*TFJobList) DeepCopyObject 

func (in *TFJobList) DeepCopyObject() runtime.Object

DeepCopyObject is an autogenerated deepcopy function, copying the receiver, creating a new runtime.Object.

type TFJobSpec 

type TFJobSpec struct {
	// Specifies the duration (in seconds) since startTime during which the job can remain active
	// before it is terminated. Must be a positive integer.
	// This setting applies only to pods where restartPolicy is OnFailure or Always.
	// +optional
	ActiveDeadlineSeconds *int64 `json:"activeDeadlineSeconds,omitempty"`

	// Number of retries before marking this job as failed.
	// +optional
	BackoffLimit *int32 `json:"backoffLimit,omitempty"`

	// Defines the policy for cleaning up pods after the TFJob completes.
	// Defaults to Running.
	CleanPodPolicy *common.CleanPodPolicy `json:"cleanPodPolicy,omitempty"`

	// Defines the TTL for cleaning up finished TFJobs (temporary
	// before kubernetes adds the cleanup controller).
	// It may take extra ReconcilePeriod seconds for the cleanup, since
	// reconcile gets called periodically.
	// Defaults to infinite.
	TTLSecondsAfterFinished *int32 `json:"ttlSecondsAfterFinished,omitempty"`

	// A map of TFReplicaType (type) to ReplicaSpec (value). Specifies the TF cluster configuration.
	// For example,
	//   {
	//     "PS": ReplicaSpec,
	//     "Worker": ReplicaSpec,
	//   }
	TFReplicaSpecs map[TFReplicaType]*common.ReplicaSpec `json:"tfReplicaSpecs"`
}

TFJobSpec is a desired state description of the TFJob.

func (*TFJobSpec) DeepCopy 

func (in *TFJobSpec) DeepCopy() *TFJobSpec

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new TFJobSpec.

func (*TFJobSpec) DeepCopyInto 

func (in *TFJobSpec) DeepCopyInto(out *TFJobSpec)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

type TFReplicaType 

type TFReplicaType common.ReplicaType

TFReplicaType is the type for TFReplica. Can be one of: "Chief"/"Master" (semantically equivalent), "Worker", "PS", or "Evaluator". 

const (
	// TFReplicaTypePS is the type for parameter servers of distributed TensorFlow.
	TFReplicaTypePS TFReplicaType = "PS"

	// TFReplicaTypeWorker is the type for workers of distributed TensorFlow.
	// This is also used for non-distributed TensorFlow.
	TFReplicaTypeWorker TFReplicaType = "Worker"

	// TFReplicaTypeChief is the type for chief worker of distributed TensorFlow.
	// If there is "chief" replica type, it's the "chief worker".
	// Else, worker:0 is the chief worker.
	TFReplicaTypeChief TFReplicaType = "Chief"

	// TFReplicaTypeMaster is the type for master worker of distributed TensorFlow.
	// This is similar to chief, and kept just for backwards compatibility.
	TFReplicaTypeMaster TFReplicaType = "Master"

	// TFReplicaTypeEval is the type for evaluation replica in TensorFlow.
