Argo: Per template exit handler.

FEATURE REQUEST: Per template exit handler.

Hi,

Could it be possible to have a per-template exit handler, instead of having a single exit handler per workflow?

Here is a couple use cases:

• We have a large workflow organized in templates, each executing a list of containers. Each template has its own clean up operations (e.g. terminate a Spark cluster that the template needed). These operations are not relevant to the other templates.

• We want to compose workflows. Workflow 1 has an exit handler. Workflow 2 has an exit handler. When we programatically merge the workflows, there is no easy way to merge the workflow-level exit handlers.

This would be really nice. For example, running a CD pipeline where at certain points the rollback situation is different.

I have a couple of similar use cases for variable cleanup behaviour, and even just specialising error notifications to our Slack channel announcing the state of the pipeline after certain failure conditions.
