​Tutorial

Use this tutorial to learn Kestra’s core concepts and build flows step by step.

You can use Kestra to:

• run workflows on demand, event-driven, or on a schedule
• interact with any system or language through plugins and tasks
• orchestrate microservices, batch jobs, scripts, SQL queries, data syncs, dbt or Spark jobs, and other processes

This tutorial starts from the “Hello world” flow in the Quickstart Guide, then adds namespaces, tasks, inputs, and triggers. Later sections cover parallel task execution, error handling, and running scripts or services in isolated containers.

Fundamentals

Start by building a simple Hello World flow.

Inputs

Inputs make your flows more dynamic and reusable.

Outputs

Outputs let you pass data between tasks and flows.

Triggers

Triggers automatically start your flow based on events.

Flowable tasks

Run tasks or subflows in parallel, create loops and conditional branching.

Error Handling

Handle errors with automatic retries and notifications.

Scripts

Kestra is language-agnostic—run custom scripts in any flow.
