Default Workflow Spec

v2.7 and after

Introduction

Default Workflow spec values can be set at the controller config map that will apply to all Workflows executed from said controller. If a Workflow has a value that also has a default value set in the config map, the Workflow's value will take precedence.

Setting Default Workflow Values

Default Workflow values can be specified by adding them under the workflowDefaults key in the workflow-controller-configmap. Values can be added as the would under the Workflow.spec tag.

For example, to specify default values that would partially produce the following Workflow:

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  generateName: gc-ttl-
  annotations:
    argo: workflows
  labels:
    foo: bar
spec:
  ttlStrategy:
    secondsAfterSuccess: 5     # Time to live after workflow is successful
  parallelism: 3

The following would be specified in the Config Map:

# This file describes the config settings available in the workflow controller configmap
apiVersion: v1
kind: ConfigMap
metadata:
  name: workflow-controller-configmap
data:
  # Default values that will apply to all Workflows from this controller, unless overridden on the Workflow-level
  workflowDefaults: |
    metadata:
      annotations:
        argo: workflows
      labels:
        foo: bar
    spec:
      ttlStrategy:
        secondsAfterSuccess: 5
      parallelism: 3
