nginx response logging

I wish there was an easy way to log http responses in nginx just as we can log the request with $request_body in the log format in access.log. I know there is a lua method to do so but thats not good because nginx official docker container image doesn't have support for these third party extensions. This should be a feature of nginx core IMO. I have been searching for the past 2 days with no easy way to setup logging of full response with body and header along with the requests.
