(solved) Serverless.yml how to create separate s3 bucket for input and output

Serverless Framework
1

EDIT: Managed to solve this… it was quite simple eventually, but I have to tell that for some reason I just did not find this…

So, I added “resourses” section to the end of serverless.yml. Down there is a new version. I write to this bucket just adding suffix “-out” to the bucket name when writing files out. Hope this helps someone else also.

Hi there!

I’m a real n00b in this serverless stuff.
I am trying to learn how to create simple serverless service, (by modifying the aws-ffmpeg-layer example).

I have succeeded to run conversions with my own setup, but only so that the input and output bucket are the same.

How should I modify my serverless yml, so that it would create separate outputbucket?
And how to access that bucket from the handler?

Here is my serverless.yml right now. This creates only one bucket (for input)
