Learn ARGO-WORKFLOWS with Real Code Examples
Updated Nov 27, 2025
Explain
Argo Workflows allows users to define multi-step workflows declaratively using YAML manifests.
Each step runs as a Kubernetes pod, allowing containerized tasks with resource isolation.
Supports DAG (Directed Acyclic Graph) and step-based workflows for complex dependencies.
Integrates natively with Kubernetes for scheduling, scaling, and resource management.
Can be used for CI/CD pipelines, data processing, machine learning workflows, and batch jobs.
Core Features
Workflow as Kubernetes custom resources
Containerized execution for each step
Support for parallel and sequential tasks
Input/output artifact management
Integration with Kubernetes RBAC, secrets, and config maps
Basic Concepts Overview
Workflow - top-level definition of a set of steps
Template - reusable step or DAG component
Step - single container task in a workflow
DAG - Directed Acyclic Graph defining dependencies between steps
Artifact - data passed between workflow steps

Building Workflow
Write YAML workflow manifest
Define steps or DAG with dependencies
Specify container images, commands, and resources
Submit workflow via Argo CLI or Kubernetes API
Monitor workflow execution via UI or CLI
Difficulty Use Cases
Beginner: single-step workflow
Intermediate: multi-step sequential workflow
Advanced: DAG workflow with parallel tasks
Expert: loops, conditional execution, and artifact passing
Enterprise: large-scale ML/ETL pipelines with cron triggers
