How should Lambdakiq be setup in app.rb?

[mtrolle]

Hi,

I've deployed an app now with Lamby and after having followed the readme of lambdakiq I've also successfully issued a job to be performed. The job enters the SQS queue and SQS also starts executing the Lambda job instance. But here it breaks:

In the previous cookiecutter documentation you created a separate Dockerfile for the jobs lambda which used a different handler to execute the ActiveJob.
But here the documentation states to use same Dockerfile. So how will lambda / sqs now what handler to fire?
I found the Lambdakiq.handler method, but not how it's fired?

Any advise? Anything I'm missing here?

Yup, ignore those now.

But here the documentation states to use same Dockerfile.

Correct, the main Dockerfile is shared for both web and jobs functions. The Lamby starter makes sure the Rails (web) Metadata is set (https://github.com/customink/lamby-cookiecutter/blob/master/%7B%7Bcookiecutter.project_name%7D%7D/template.yaml#L26-L28) so all you have to do is make another function as described here (https://github.com/customink/lambdakiq#iam-permissions) note how it has a DockerTag of (jobs) and there are comments below on why that is important.

Oh crap! I think I missed a very important part of the docs... one sec...

That did the trick - thanks!
