How to run an existing Argo Workflow after completion of another Argo workflow?

Question

So I have a Argo workflow_B that needs to run after completion of Argo workflow_A which is used by another team. Both workflows already exist I just want to chain them together. How can I achieve that?

Is it possible to do such thing using exit-handler? or should I use event-source like Webhook or AWS SNS to do that?

Answer 1

Have you looked at the workflow of workflows pattern? If team A is able to create workflow on team b namespace
