Argo Workflows

Kubernetes-native workflow engine that executes containerized DAG and Steps-based workflows with artifact passing between steps, retry strategies, workflow templates for reuse, and a REST API for programmatic submission and monitoring.

Native Kubernetes RBAC integration is a strong security positive. Secrets should be passed via Kubernetes Secrets volumes, not workflow parameters. Pod security policies or PSA should be configured to prevent privilege escalation in workflow containers.

Best When

Orchestrating containerized batch workflows, ML pipelines, or data processing DAGs on an existing Kubernetes cluster where native K8s RBAC and resource management are required.

Avoid When

You don't have a Kubernetes cluster or your workflows are simple enough that a managed CI/CD service (GitHub Actions, Airflow) would reduce operational overhead.

Use Cases

  • Submit a multi-step ML training pipeline as a DAG Workflow via REST API with artifact passing between data prep, training, and evaluation steps
  • Create a WorkflowTemplate for a reusable ETL pattern and invoke it programmatically with different parameters via the Argo Workflows REST API
  • Poll workflow execution status and retrieve step-level logs via the REST API to track long-running batch jobs from an external orchestration system
  • Configure retry strategies (retryStrategy.limit, backoff) on individual DAG nodes to handle flaky steps without rerunning the entire workflow
  • Use RBAC-scoped ServiceAccount tokens to submit workflows to specific Kubernetes namespaces with least-privilege access from a CI/CD pipeline

Not For

  • Simple sequential CI/CD pipelines where GitHub Actions or GitLab CI would be simpler and require no Kubernetes cluster
  • Teams without Kubernetes infrastructure — Argo Workflows requires a running K8s cluster and cannot run standalone
  • Event streaming or real-time data processing workloads better suited to Kafka or Flink

Authentication

Methods: kubernetes_serviceaccount bearer_token sso
OAuth: Yes Scopes: Yes

Authentication uses Kubernetes ServiceAccount tokens (projected or static). RBAC is enforced via Kubernetes ClusterRole/Role bindings. SSO via OIDC is supported for UI access. REST API requires Bearer token in Authorization header.

Pricing

Requires CC: No

CNCF graduated open source project. Codefresh offers a managed Argo Workflows service for teams that don't want to self-manage.

Known Gotchas

  • Workflow names must be unique within a namespace; always use generateName instead of name for programmatic submission to avoid conflict errors on re-runs
  • Artifact passing between steps requires a configured artifact repository (S3, GCS, or Minio); workflows silently skip artifact storage if not configured, causing downstream steps to fail with 'artifact not found'
  • The Argo Server REST API requires the workflow-controller and argo-server pods to be running; submitting via kubectl apply is an alternative that bypasses the server but lacks status tracking
  • ServiceAccount token permissions must include 'pods/log' get access in addition to workflow permissions for log retrieval via the API to succeed
  • WorkflowTemplate entrypoint must be explicitly specified on submission if the template has multiple entrypoints; omitting it uses the first defined entrypoint which may not be the intended one
