What is Argo Workflows?

Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. Argo Workflows is implemented as a Kubernetes CRD (Custom Resource Definition).

Define workflows where each step in the workflow is a container.
Model multi-step workflows as a sequence of tasks or capture the dependencies between tasks using a directed acyclic graph (DAG).
Easily run compute intensive jobs for machine learning or data processing in a fraction of the time using Argo Workflows on Kubernetes.

Argo is a Cloud Native Computing Foundation (CNCF) hosted project.

Use Cases

Why Argo Workflows?

Argo Workflows is the most popular workflow execution engine for Kubernetes.
Light-weight, scalable, and easier to use.
Designed from the ground up for containers without the overhead and limitations of legacy VM and server-based environments.
Cloud agnostic and can run on any Kubernetes cluster.
