​Developer ​Guide

Develop Python, R, Shell, PowerShell, Julia, Ruby or Node.js scripts and integrate them with Git and CI/CD.

Data storage and processing

Kestra's primary purpose is to orchestrate data processing via tasks, so data is central to each flow's execution.

Errors and retries

Errors are special branches of a flow where you can define how to react to task failures (e.g. send an email, open a ticket, etc.).

Namespace Files

This page covers the concept of Namespace Files and how to use them in your flows.

Version Control with Git

Kestra supports version control with Git. You can use one or more Git repositories to store your Flows and Namespace Files, and track changes to them over time via Git commit history.

Caching

Kestra provides a file caching, which is especially useful when you work with sizeable package dependencies that don't change often.

Build a Custom Plugin

Browse Kestra's integrations and learn how to create your own plugins.

Python, R, Node.js and Shell Scripts

Kestra is language agnostic. You can orchestrate custom business logic written in Python, R, Julia, Ruby, Node.js, Powershell and Shell scripts, and you can also build custom plugins in Java.

Create a CI/CD pipeline

Kestra provides several ways to create a CI/CD pipeline for your flows. This section explains how to automate the validation and deployment of your workflows using CI/CD.
