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

Machine Learning pipelines
Data and batch processing
ETL
Infrastructure automation
CI/CD

Why Argo Workflows?

Argo Workflows is the most popular workflow execution engine for Kubernetes.
It can run 1000s of workflows a day, each with 1000s of concurrent tasks.
Our users say it is lighter-weight, faster, more powerful, 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.
