Failed to build docker image about arrow-ballista

I guess you are building the image with root or sudo to run. Use another with the permission to use docker command could resolve the issue. However the script assumes build with non-root user.

@zhangyuan Thank you for your suggestion that solved part of my problem, I say this because I also need to set permissions to some scripts before performing any steps (after git clone of course), i.e. chmod a+rwx ./dev/docker/* .sh, this works for me.

BTW, documentation for Ballista is a bit old and incorrect, which puts some people off.
