Here is what I cobbled together for serverless Lambda deployments based on the helpful comments here. This could be improved by specifying your account id instead of allowing *. I was unsure which role should be allowed for iam:GetRole and ended up specifying * for that. If anyone knows which roles should be allowed there please comment.

I wanted to share my thoughts on the serverless security project. As a developer, I am surprised to see that there is not enough official documentation available for such a critical point.
Why are there so few contributions? Could it be because everyone is granting full rights ?

Personally, I've tested the configurations provided in this gist, but unfortunately, they didn't work as expected. It appears that certain permissions are missing with the last version of serverless.

I suggest creating a minimum, tested roles file with proper permissions.

I'm currently working on my own configuration, and once it's complete, I will share it with the community.

Great! Can't wait for your configuration!
