I try to create my own base images and I have one question and two problems regarding that.
A question, out of idle curiosity: how does Dockerfile with
FROM resin/raspberrypi3-debianmanages to build on a mac? I was really surprised that it worked on my machine (because arm and x86 are quite different beasts).
Why the same Dockerfile that worked locally fails to build an image on docker cloud services (both hub and cloud):
Building in Docker Cloud's infrastructure... Cloning into '.'... Warning: Permanently added the RSA host key for IP address '184.108.40.206' to the list of known hosts.

Are there any workarounds? I’d prefer to just push code of my base image to repository and not to build and push docker image to docker cloud manually after that.
I’ve noticed that https://hub.docker.com/r/resin/raspberrypi3-debian/ is also not auto-built, so I suppose resin.io team has the same problem.
- How can I pull a private base image from Docker hub for resin.io device? I was able to use a public image for that, now how do I tell resin my docker credentials?
