"lstat service: no such file or directory" error in docker running gateway

Hey guys, I’m running into this error when building in docker. Any ideas on how to fix it?

It happens at `ADD Service etc/service’ line of the dockerfile.

Are you using the https://github.com/mozilla-iot/gateway-docker repo?

Assuming you are, my typical build process is the following:

cd ~/workspace/gateway-docker
git pull
docker build --pull --build-arg gateway_branch=v0.9.1 -t gateway .
