maven package docker:build - connection refused

Question

I am trying to directly build a docker image with maven with mvn package docker:build.

Docker is running and docker ps shows me my containers,

On windows 7 64 the docker env seems a bit tricky to install as it requires a linuxVM to run (update issues with previous vbox installation) https://github.com/docker/machine/issues/3396 )

Luckily in the docker quickstart terminal we can do:

   $ docker-machine.exe env
   export DOCKER_TLS_VERIFY="1"
   export DOCKER_HOST="tcp://192.168.99.101:2376"
   export DOCKER_CERT_PATH="C:\Users\uv\.docker\machine\machines\default"
   export DOCKER_MACHINE_NAME="default"
   # Run this command to configure your shell:
   # eval $("C:\Program Files\Docker Toolbox\docker-machine.exe" env)

showing us what to put into the plugin configuration

   https://192.168.99.101:2376

but only after using the advice found here:

Docker: An error occurred trying to connect

with the important part being:

Run FOR /f "tokens=*" %i IN ('docker-machine env --shell cmd default') DO %i

we can run the mvnw docker:build successfully in the cmd/intellij terminal :)
