How to catch started rollout event?

[danil-smirnov]

As per docs, we have some notifications triggers predefined but I didn't find one triggered on a new rollout start. That trigger seems useful for Grafana annotations if we want to catch a period between rollout start and completion/abort. Any ideas?

I've created a custom trigger like this:

      trigger.on-rollout-started: |
        - send: [rollout-started]
          when: rollout.status.phase == 'Progressing' and rollout.status.currentStepIndex == 0

Maybe it can be included in the list of default triggers?

Just to add another option as well

trigger.on-rollout-updated-webhook: |
    - send: [rollout-json]
      when: rollout.status != nil && rollout.status.stableRS != rollout.status.currentPodHash
      oncePer: rollout.metadata.annotations["rollout.argoproj.io/revision"]

There is also the event based version: https://github.com/argoproj/argo-rollouts/blob/master/manifests/notifications/on-rollout-updated.yaml

Thank you @zachaller but as I see in the docs:

on-rollout-updated when a rollout definition is changed

I'm not sure how it's related to the rollout started event...
