Argo Workflows

Argo Workflows is an open source engine that runs parallel jobs on Kubernetes, where each workflow step is executed in its own container. It is implemented as a Kubernetes custom resource definition, so workflows are defined as Kubernetes resources.

Workflows are modelled as a sequence of steps or as a directed acyclic graph of tasks with dependencies, and can pass artefacts and parameters between steps. Typical uses are compute-intensive machine learning and data processing jobs, and CI/CD pipelines run natively on Kubernetes, including test suites. It runs on any Kubernetes cluster and provides a command-line tool and a web interface to submit and follow workflows.

Argo Workflows is part of the Argo project and is free and open source under the Apache 2.0 licence.
