Workflow arguments value in UI

[julianacg]

Hello,
I was wondering if there is a way to get the actual value passed to the workflow arguments on submit directly in the UI. I can see that template inputs and outputs are visible with the right values but this is not the case for workflow arguments.

I have been trying to parametrize image tag, which work fine but after workflow execution i cannot see the value of the tag unless i go directly into kubernetes to get the rendered yaml.

Here is an example

apiVersion: argoproj.io/v1alpha1
kind: WorkflowTemplate
metadata:
  name: custom-tag-wt
spec:
  entrypoint: dag
  arguments:
    parameters:
    - name: tag
      value: alpine3.6
  templates:
  - name: container
    serviceAccountName: argo-workflow
    container:
      image: python:{{workflow.parameters.tag}}
      command: ["python", -c]
      args: ["import random; import sys; exit_code = random.choice([0, 0, 1]); sys.exit(exit_code)"]
  - name: dag
    dag:
      tasks:
      - name: step-1
        template: container
      - name: step-2
        template: container
      - name: step-3
        template: container
        dependencies: [step-1, step-2]

The workflow node summary has no arguments field

And the template container doesnt interpolate values

If you want to use an input that you can specify when calling the workflow template from the UI or other places, don't specify the tag as arguments.parameters, but as input:

spec:
  templates:
    - name: container
      inputs:
        parameters:
          - name: tag
            description: >
              The container image tag to use.

Then use it as {{inputs.parameters.tag}}
