Workflow Templates

The Workflow Templates page displays Argo WorkflowTemplates deployed in your cluster. View template details and visualize workflow DAGs (Directed Acyclic Graphs).

Prerequisites

This feature requires Argo Workflows to be installed in your cluster.

Install Argo Workflows using the bundled devspace deployment:

cd services/argo-workflows
devspace dev

See Argo Workflows for detailed installation instructions.

Accessing Workflow Templates

Navigate to Workflow Templates from the dashboard sidebar or visit:

http://dashboard.127.0.0.1.nip.io:8080/workflow-templates

Template List

The main page displays all WorkflowTemplates in your namespace:

  • Name - Template identifier
  • Description - Template description from annotations
  • Created - Creation timestamp

Click any template to view its details.

Template Details

The detail view shows:

DAG Visualization

Visual representation of the workflow graph showing:

  • Nodes - Individual workflow steps
  • Edges - Dependencies between steps
  • Layout - Hierarchical top-to-bottom flow

Template Information

  • Name - Template name
  • Namespace - Kubernetes namespace
  • Entrypoint - Starting workflow step
  • Templates - Available template definitions

DAG Viewer

The DAG viewer provides:

  • Interactive visualization - Pan and zoom
  • Node details - Step names and types
  • Dependency flow - Visual connection between steps
  • Auto-layout - Automatic hierarchical positioning
  • Pan - Click and drag the canvas
  • Zoom - Mouse wheel or pinch gesture

Creating Workflow Templates

Simple DAG Example

Save this to a file (e.g., simple-pipeline.yaml):

apiVersion: argoproj.io/v1alpha1
kind: WorkflowTemplate
metadata:
  name: simple-data-pipeline
  annotations:
    workflows.argoproj.io/description: "Process data through multiple stages"
spec:
  entrypoint: pipeline
  templates:
  - name: pipeline
    dag:
      tasks:
      - name: collect
        template: task-template
        arguments:
          parameters:
          - name: message
            value: "Collecting data"
 
      - name: validate
        template: task-template
        dependencies: [collect]
        arguments:
          parameters:
          - name: message
            value: "Validating data"
 
      - name: transform
        template: task-template
        dependencies: [validate]
        arguments:
          parameters:
          - name: message
            value: "Transforming data"
 
      - name: load
        template: task-template
        dependencies: [transform]
        arguments:
          parameters:
          - name: message
            value: "Loading data"
 
  - name: task-template
    inputs:
      parameters:
      - name: message
    container:
      image: alpine:latest
      command: [echo]
      args: ["{{inputs.parameters.message}}"]

Apply it:

kubectl apply -f simple-pipeline.yaml

The template will appear in the dashboard where you can view the DAG visualization.
