Docker seems to be unavailable. Is it installed and running?

I am trying work my way through the getting started guide for openBalena using a screenly image. I am running Windows 7 and installed docker with docker-toolbox. I am using GitBash and I can run docker -v and get the version of docker returned. I am on the step where I need to run

balena deploy screenly --logs --source . --emulated

but I am getting the error

Docker seems to be unavailable. Is it installed and running?

I have looked on this forum and saw this as a solution for Windows 10 and thought I would try it but did not work either.

balena deploy screenly --logs --source . --emulated --build --docker=//./pipe/docker_engine

I know I need to specify another parameter for docker but I don’t know what that is or where to find it. I have seen some using dockerHost and dockerPort but I don’t know that information.

Hello, can you please try running the deploy command with DEBUG=1? Also, can you try pulling an image, eg docker pull busybox? It would also be useful to find the value of the DOCKER_HOST env var – I believe set | grep DOCKER would do it.
