Argo Workflows

Argo Workflows is an open-source, container-native workflow engine for orchestrating parallel jobs on Kubernetes. It is a CNCF graduated project that allows you to define workflows where each step is a container, model multi-step workflows as sequences of tasks or DAGs, and run compute-intensive jobs for machine learning, data processing, and CI/CD pipelines natively on Kubernetes. Governed by the Linux Foundation and the CNCF.

Argo Workflows publishes 11 APIs on the APIs.io network, including ArchivedWorkflowService API, ArtifactService API, ClusterWorkflowTemplateService API, and 8 more. Tagged areas include CNCF, Containers, Data Processing, Kubernetes, and Machine Learning.

The Argo Workflows catalog on APIs.io includes 7 JSON-LD contexts and 2 Spectral governance rulesets.

Argo Workflows’ developer surface includes authentication, engineering blog, documentation, getting-started guide, release notes, changelog, CLI, and 10 more developer resources.
