Constants

const (
	// PolicyInMemory provides an inmemory Workflow store which is useful for testing
	PolicyInMemory = "InMemory"
	// PolicyPassThrough just calls the underlying Clientset or the shared informer cache to get or write the workflow
	PolicyPassThrough = "PassThrough"
	// PolicyResourceVersionCache uses the resource version on the Workflow object, to determine if the inmemory copy
	// of the workflow is stale
	PolicyResourceVersionCache = "ResourceVersionCache"
)

Variables

var ErrStaleWorkflowError = fmt.Errorf("stale Workflow Found error")

ErrStaleWorkflowError signals that the local copy of workflow is Stale, i.e., a new version was written to the datastore, But the informer cache has not yet synced to the latest copy

var ErrWorkflowNotFound = fmt.Errorf("workflow not-found error")

ErrWorkflowNotFound indicates that the workflow does not exist and it is safe to ignore the event

var ErrWorkflowTerminated = fmt.Errorf("workflow has already been terminated")

ErrWorkflowTerminated indicates that the workflow being operated on has previously been stored in a terminal state.

var ErrWorkflowToLarge = fmt.Errorf("workflow too large")

ErrWorkflowToLarge is returned in cased an update operation fails because the Workflow object (CRD) has surpassed the Datastores supported limit.

Functions

func IsNotFound

func IsNotFound(err error) bool

IsNotFound returns true if the error is caused by ErrWorkflowNotFound

func IsWorkflowStale

func IsWorkflowStale(err error) bool

IsWorkflowStale returns true if the error is caused by ErrStaleWorkflowError

func IsWorkflowTerminated

func IsWorkflowTerminated(err error) bool

IsWorkflowTerminated returns true if the error is caused by ErrWorkflowTerminated

func IsWorkflowTooLarge

func IsWorkflowTooLarge(err error) bool

IsWorkflowTooLarge returns true if the error is caused by ErrWorkflowToLarge

func SetConfig

func SetConfig(cfg *Config) error

Types

type Config

type Config struct {
	Policy Policy `json:"policy" pflag:",Workflow Store Policy to initialize"`
}

Config for Workflow access in the controller. Various policies are available like - InMemory, PassThrough, ResourceVersionCache

func GetConfig

func GetConfig() *Config

func (Config) GetPFlagSet

func (cfg Config) GetPFlagSet(prefix string) *pflag.FlagSet

GetPFlagSet will return strongly types pflags for all fields in Config and its nested types. The format of the flags is json-name.json-sub-name... etc.

type FlyteWorkflow

type FlyteWorkflow interface {
	Get(ctx context.Context, namespace, name string) (*v1alpha1.FlyteWorkflow, error)
	UpdateStatus(ctx context.Context, workflow *v1alpha1.FlyteWorkflow, priorityClass PriorityClass) (
		newWF *v1alpha1.FlyteWorkflow, err error)
	Update(ctx context.Context, workflow *v1alpha1.FlyteWorkflow, priorityClass PriorityClass) (
		newWF *v1alpha1.FlyteWorkflow, err error)
}

FlyteWorkflow store interface provides an abstraction of accessing the actual FlyteWorkflow object.

func NewPassthroughWorkflowStore

func NewPassthroughWorkflowStore(_ context.Context, scope promutils.Scope, wfClient v1alpha12.FlyteworkflowV1alpha1Interface,
	flyteworkflowLister listers.FlyteWorkflowLister) FlyteWorkflow

func NewResourceVersionCachingStore

func NewResourceVersionCachingStore(_ context.Context, scope promutils.Scope, workflowStore FlyteWorkflow) (FlyteWorkflow, error)

func NewWorkflowStore

func NewWorkflowStore(ctx context.Context, cfg *Config, lister v1alpha1.FlyteWorkflowLister,
	workflows flyteworkflowv1alpha1.FlyteworkflowV1alpha1Interface, scope promutils.Scope) (FlyteWorkflow, error)

type InmemoryWorkflowStore

type InmemoryWorkflowStore struct {
	// contains filtered or unexported fields
}

func NewInMemoryWorkflowStore

func NewInMemoryWorkflowStore() *InmemoryWorkflowStore

Returns an inmemory store, that will update the resource version for every update automatically. This is a good idea to test that resource version checks work, but does not represent that the object was actually updated or not The resource version is ALWAYS updated.

func (*InmemoryWorkflowStore) Create

func (i *InmemoryWorkflowStore) Create(ctx context.Context, w *v1alpha1.FlyteWorkflow) error

func (*InmemoryWorkflowStore) Delete

func (i *InmemoryWorkflowStore) Delete(ctx context.Context, namespace, name string) error

func (*InmemoryWorkflowStore) Get

func (i *InmemoryWorkflowStore) Get(ctx context.Context, namespace, name string) (*v1alpha1.FlyteWorkflow, error)

func (*InmemoryWorkflowStore) Update

func (i *InmemoryWorkflowStore) Update(ctx context.Context, w *v1alpha1.FlyteWorkflow, priorityClass PriorityClass) (
	newWF *v1alpha1.FlyteWorkflow, err error)

func (*InmemoryWorkflowStore) UpdateStatus

func (i *InmemoryWorkflowStore) UpdateStatus(ctx context.Context, w *v1alpha1.FlyteWorkflow, priorityClass PriorityClass) (
	newWF *v1alpha1.FlyteWorkflow, err error)

type Policy

type Policy = string

type PriorityClass

type PriorityClass int

const (
	PriorityClassCritical PriorityClass = iota
	PriorityClassRegular
)
