Run Steps on Remote Cluster

[hyorigo]

Summary

We want to figure out best/simplest practice to run steps on remote cluster.

Already read through and tried the admiraltyio/multicluster-scheduler solution, however it's kinda complicated and overwhelming for our scenarios:

• https://admiralty.io/blog/running-argo-workflows-across-multiple-kubernetes-clusters/
• https://itnext.io/multicluster-scheduler-argo-workflows-across-kubernetes-clusters-ea98016499ca

Working with only Argo itself, is there any possible or solution to let argo-server of Argo on one cluster, and workflow-controller of Argo to create/watch step pods on the other cluster?

Motivation

We're building a specific CI/CD based on Argo, for some performance testing or test cases involving GPU nodes scenarios, the step pods should be running on the same remote cluster with the testbed pods. And we want to minimize the changes upon the remote clusters.

Argo Workflows is designed to be install into the cluster it is needed for. We do not currently support multi-cluster. See #3523

@alexec Thanks for your reply! So it's kinda design problem.

Is it hard/complicated to adjust Argo Workflow Controller for this purpose? Or it's nearly impossible to make such a change since it's the root of Argo and its design.

[CaramelMario]

The same. @alexec Is it a big big change, or maybe possible the fork and make a quick fix for this?
