cache_from works with docker, not with docker-compose v3.2 #5090
Description
Hey,
I'm experiencing some strange behaviour.
See the following docker build:
$ docker build -t eu.gcr.io/peopledata-product-team/td.gateway . --cache-from eu.gcr.io/peopledata-product-team/td.gateway:latest

As you can see, nicely cached.
However trying to do the same thing with compose I get cache invalidations. I find it interesting it does seem to cache up until the point of a file based copy (the env/expose are fine).
