Hi All,
I am trying to see if there is a way I can suspend a workflow based on parameter rather than directly giving the string, as stated in the doc ?
Thank you

The ability to parameterize the suspend template duration field was introduced in Argo Workflows version 3.5. This allows expressions like duration: "{{workflow.parameters.duration}}".

suspend:
  duration: "{{workflow.parameters.duration}}" # Could be "10s", "2m", "6h", or "10" ("10" defaults to seconds)

This enhancement enables dynamic suspension durations based on workflow parameters.

Functional example using a workflow parameter:

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  name: suspend-duration-parameter
  namespace: argo
spec:
  templates:
    - name: suspend-workflow
      steps:
        - - name: suspend-step
            template: suspend-template
    - name: suspend-template
      suspend: # suspend template
        duration: "{{workflow.parameters.duration}}" # Variable duration value based on workflow parameter
  entrypoint: suspend-workflow
  arguments:
    parameters:
      - name: duration # Workflow duration parameter
        value: 10s # Passing a Duration value as a workflow parameter
