What is it?

Argo Events is a framework for running automation on Kubernetes in response to external or internal events. It connects event sources such as webhooks, S3 uploads, cron schedules, and messaging systems like Kafka, GCP Pub/Sub, SNS, and SQS to actions such as creating Kubernetes objects, invoking Argo Workflows, or calling serverless workloads.

Events are described with CloudEvents-compliant payloads, and sensors can apply conditional logic so that a trigger fires only when a business rule is met. The project supports simple linear event flows as well as more complex setups that combine multiple event sources.

It is installed on a Kubernetes cluster and managed through its own custom resources, with documentation covering installation, concepts, and tutorials.

Key features

  • 01Supports 20+ event sources including webhooks, S3, cron, Kafka, and SQS.
  • 02Offers 10+ trigger types such as creating Kubernetes objects or invoking workflows.
  • 03Allows conditional logic to control when triggers fire.
  • 04Follows the CloudEvents specification for event data.

Use cases

  • Starting an Argo Workflows pipeline when a file lands in an S3 bucket.
  • Triggering CI/CD jobs from incoming webhooks from Git or other systems.
  • Running scheduled Kubernetes jobs with cron-based events.
  • Reacting to messages from Kafka or SQS by launching serverless workloads.

Quick start

  1. 1

    Follow the installation guide linked in the README

Things to know

  • It runs on Kubernetes, so you need a Kubernetes cluster to use it.
  • Setup follows external documentation rather than a single install command.
