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
