Forwarding Lambda Requests

[joe4dev]

Hi @culture_tires

@culture_tires

1. My service depends on a Lambda maintained by another team.
2. I don’t care about the internal of the Lambda, just need to mock its API.
3. I’d like to provide the mocked responses via a mockserver instance.

Thank you very much for sharing your use case. That is indeed a very interesting scenario.

And my hack/solution described above is a bit of an overkill, for two reasons;

1. the python script that needs to be maintain, deployed, etc
2. the fact that it spin up another container which needs access to mockserver instance, networking is not straightforward.

Makes sense.

The previous implementation of LAMBDA_FORWARD_URL sent a POST request to the given URL with the lambda-function-name in the header and input event as JSON body. I guess that should be sufficient to cover the mockserver scenario or are there any special requirements to consider?

I added the feature to our internal Lambda backlog. We continuously monitor popular GitHub feature requests and Discuss posts when prioritizing our efforts to improve LocalStack.

Best,
Joel
