How to specify multiple resources in a single entry in serverless.yml?

Question

I would like to be able to specify multiple resources using a single entry in serverless.yml.

My use case is as follows:

reportFatalError:
    handler: "handler.reportFatalError"
    events:
    - cloudwatchLog:
        # "*" implies wish to insert wildcard
        logGroup: "/aws/lambda/*-${opt:stage}-*"
        filter: "\"FATAL\""

Naturally, I would like the Fatal Error Reporter to report the Fatal Error from any logGroup, and explicitly specifying all of them is a recipe for poorly maintained serverless.yml in the future.

Is there some way to specify a wildcard or loop over the logGroups as serverless deploys?

Answer 1

Unfortunately there isn't a way to do this with wildcards. This is a limitation of AWS, not Serverless.

You could write a script that loaded a list of all your CloudWatch logGroups and then applied those events to your reportFatalError function on deployment.
