Running workflows

Workflows on their own are not runnable directly. However, a launchplan is always bound to a workflow and you can use launchplans to launch a workflow. For cases in which you want the launchplan to have the same arguments as a workflow, if you are using one of the SDK’s to author your workflows - like flytekit, flytekit-java etc, then they should automatically create a default launchplan for the workflow.

A default launchplan has the same name as the workflow and all argument defaults are similar. See Launch plans to run a workflow via the default launchplan.

Tasks also can be executed using the launch command. One difference between running a task and a workflow via launchplans is that launchplans cannot be associated with a task. This is to avoid triggers and scheduling.


Workflows can be executed with FlyteRemote because under the hood it fetches and triggers a default launch plan.

from flytekit.remote import FlyteRemote
from flytekit.configuration import Config

# FlyteRemote object is the main entrypoint to API
remote = FlyteRemote(

# Fetch workflow
flyte_workflow = remote.fetch_workflow(name="", version="v1")

# Execute
execution = remote.execute(
    flyte_workflow, inputs={"mean": 1}, execution_name="workflow-execution", wait=True

# Or use execution_name_prefix to avoid repeated execution names
execution = remote.execute(
    flyte_workflow, inputs={"mean": 1}, execution_name_prefix="flyte", wait=True
