Enable --retry flag for background functions

[0xkalle]

I started using Google Cloud Functions to subscribe to a pub/sub topic. The problem is, that by default Pub/Sub messages are acknowledged on receive and not when the function executed successfully.

If I would use the gcloud CLI for the deployment of the function, I would add the --retry flag.

Is it somehow possible to do that now?

As it is not possible to include this in the serverless.yml yet, I would suggest something like this:

functions:
  handlerNameFunction:
    handler: handlerName
    events:
      - event:
          eventType: providers/cloud.pubsub/eventTypes/topic.publish
          resource: projects/:projectId/topics/:topic
          retry: true

with a default to false

or if we want to be able to also add future flags:

functions:
  handlerNameFunction:
    handler: handlerName
    events:
      - event:
          eventType: providers/cloud.pubsub/eventTypes/topic.publish
          resource: projects/:projectId/topics/:topic
          flags:
            - retry

1. Is there a way to sneak this flag in already?
2. What do you think of the suggested addition?

Best,
Kalle

Any news on this?

Maybe this behaviour has changed? I notice that the signature shown for pubsub handlers in serverless does not match the signature shown in Google's examples as well.

I like the extensible flags: array option.
