Caching doesn't work for me

[dmcd]

Hi there,

I have a python image that takes 25mins to build (it includes gdal libraries that aren't yet available in alpine) so I'm trying to use the caching feature but haven't been able to get it to work, probably related to this: drone-plugins/drone-docker#34

Some output from my build:
