snapcraft in docker container fails

[Marco Ceppi]

Hi Alistair,

We had a similar issue in our project, we found this:

docker run -it -v $PWD:/root/snap -w /root/snap -e SNAPCRAFT_SETUP_CORE=1
snapcraft/xenial-amd64 /bin/bash

Where, when using that flag, the core snap will already be installed.

Thanks,
Marco Ceppi
