Retrying Argo Rollouts After a promote-full Action via the GUI

[wagnerduartewexinc]

Hi everyone,

I'm currently working with Argo Rollouts integrated into Argo CD, and I’ve run into a situation that I’d like to open up for discussion:

When performing a canary rollout, it's common to hit a failure during or after a promote-full action—especially if something goes wrong right after promoting the new version to 100%. While I know the Argo CD GUI supports retries for certain paused or failed rollout states (e.g., failed analysis), it seems that once a promote-full has been issued and a failure occurs after that point, there's no visible retry button or direct way to resume the rollout from the GUI.

What I'd like to discuss:
Is there currently a way to manually retry a rollout after a promote-full from the Argo CD GUI?

If not, would it make sense to support this as a feature?

In my case, the rollout failed just after the promotion (e.g., due to a post-promotion check or a bad configuration), and I wanted to avoid reverting or re-syncing everything just to try again.

From a user experience standpoint, a GUI option to "retry from last failure" or "restart from current state" after promotion could be really helpful.

Would love to hear how others are handling this, and if this is something already possible or worth exploring as a feature request.

Thanks!
