Both AWS Lambda and Google Cloud Functions allows using a .zip file with Python code and requirements in it. AWS Lambda publishes https://gallery.ecr.aws/lambda/python docker images that simulate the runtime environment for lambda, meaning one can put code into that docker image and run it locally in close to the same way it runs in the cloud. Does anyone know of GCF publishing similar images? Docs like https://cloud.google.com/functions/docs/concepts/python-runtime make no mention of it (NB. this is different to building and running a docker image on either environment: I want to simulate the 'normal' runtime environment, down to the version of glibc.)
