Functions

func FlyteTaskToBatchInput

func FlyteTaskToBatchInput(ctx context.Context, tCtx pluginCore.TaskExecutionContext, jobDefinition string, cfg *config2.Config) (
	batchInput *batch.SubmitJobInput, err error)

Note that Name is not set on the result object. It's up to the caller to set the Name before creating the object in K8s.

func GetJobTaskLog

func GetJobTaskLog(jobSize int, accountID, region, queue, jobID string) *idlCore.TaskLog

func GetJobURI added in v0.3.11

func GetJobURI(jobSize int, accountID, region, queue, jobID string) string
func GetTaskLinks(ctx context.Context, taskMeta pluginCore.TaskExecutionMetadata, jobStore *JobStore, state *State) (
	[]*idlCore.TaskLog, error)

func TerminateSubTasks

func TerminateSubTasks(ctx context.Context, tCtx core.TaskExecutionContext, batchClient Client, reason string, metrics ExecutorMetrics) error

Attempts to terminate the AWS Job if one is recorded in the pluginState. This API is idempotent and should be safe to call multiple times on the same job. It'll result in multiple calls to AWS Batch in that case, however.

func UpdateBatchInputForArray

func UpdateBatchInputForArray(_ context.Context, batchInput *batch.SubmitJobInput, arraySize int64) *batch.SubmitJobInput

Types

type ArrayJobSummary

type ArrayJobSummary map[JobPhaseType]int64

type Attempt

type Attempt struct {
	LogStream string    `json:"logStream,omitempty"`
	StartedAt time.Time `json:"startedAt,omitempty"`
	StoppedAt time.Time `json:"stoppedAt,omitempty"`
}

type BatchServiceClient

type BatchServiceClient interface {
	SubmitJobWithContext(ctx a.Context, input *batch.SubmitJobInput, opts ...request.Option) (*batch.SubmitJobOutput, error)
	TerminateJobWithContext(ctx a.Context, input *batch.TerminateJobInput, opts ...request.Option) (*batch.TerminateJobOutput, error)
	DescribeJobsWithContext(ctx a.Context, input *batch.DescribeJobsInput, opts ...request.Option) (*batch.DescribeJobsOutput, error)
	RegisterJobDefinitionWithContext(ctx a.Context, input *batch.RegisterJobDefinitionInput, opts ...request.Option) (*batch.RegisterJobDefinitionOutput, error)
}

BatchServiceClient is an interface on top of the native AWS Batch client to allow for mocking and alternative implementations.

type Client

type Client interface {
	// Submits a new job to AWS Batch and retrieves job info. Note that submitted jobs will not have status populated.
	SubmitJob(ctx context.Context, input *batch.SubmitJobInput) (jobID string, err error)

	// Attempts to terminate a job. If the job hasn't started yet, it'll just get deleted.
	TerminateJob(ctx context.Context, jobID JobID, reason string) error

	// Retrieves jobs' details from AWS Batch.
	GetJobDetailsBatch(ctx context.Context, ids []JobID) ([]*batch.JobDetail, error)

	// Registers a new Job Definition with AWS Batch provided a name, image and role.
	RegisterJobDefinition(ctx context.Context, name, image, role string) (arn string, err error)

	// Gets the single region this client interacts with.
	GetRegion() string

	GetAccountID() string
}

AWS Batch Client interface.
