I had a docker script with a RUN directive apt-get install git that just stalled.

This issue was that it was awaiting y/n responses about how whether I was willing to install given that it would use up X-mb in space.

Lesson:

Whenever scripting a build or deploy process or docker container, use non-interactive versions of the commands (e.g. apt-get install -y git) otherwise it will stall forever or fail.
