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.
