One Workflow Submitting Another

GA

v2.8 and after

If you want one workflow to create another, you can do this using curl. You'll need an access token. Typically the best way is to submit from a workflow template:

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  generateName: demo-
spec:
  entrypoint: main
  templates:
    - name: main
      steps:
        - - name: a
            template: create-wf
    - name: create-wf
      script:
        image: curlimages/curl:latest
        command:
          - sh
        source: >
          curl https://argo-server:2746/api/v1/workflows/argo/submit \
            -fs \
            -H "Authorization: Bearer eyJhbGci..." \
            -d '{"resourceKind": "WorkflowTemplate", "resourceName": "wait", "submitOptions": {"labels": "workflows.argoproj.io/workflow-template=wait"}}'
