Executions are instances of workflows, nodes or tasks created in the system as a result of a user-requested execution or a scheduled execution.
Typical Flow Using Flytectl#
When an execution of a workflow is triggered using UI/Flytecli/other stateless systems, the system first calls the
getLaunchPlanendpoint and retrieves a launch plan matching the given version. The launch plan definition includes definitions of all input variables declared for the workflow.
The user-side component then ensures that all the required inputs are supplied and requests the FlyteAdmin service for an execution.
The FlyteAdmin service validates the inputs, ensuring that they are all specified and, if required, within the declared bounds.
FlyteAdmin then fetches the previously validated and compiled workflow closure and translates it to an executable format with all the inputs.
This executable workflow is launched on Kubernetes with an execution record in the database.
