Types

type Workflow

type Workflow interface {
	// ExecuteSteps executes the steps of an Application with given steps of rendered resources.
	// It returns done=true only if all steps are executed and succeeded.
	ExecuteSteps(ctx monitorContext.Context, appRev *v1beta1.ApplicationRevision, taskRunners []types.TaskRunner) (state common.WorkflowState, err error)

	// Trace record workflow state in controllerRevision.
	Trace() error

	// GetBackoffWaitTime returns the wait time for next retry.
	GetBackoffWaitTime() time.Duration
}

Workflow is used to execute the workflow steps of Application.
