1.4.0 dockerfile?

[iwarshak]

The 1.4.0 build image is in dockerhub, and it has broken our CI server. Any chance you could publish the dockerfile for 1.4.0?

@iwarshak sorry, totally forgot to push it here! Just did.

@iwarshak were you able to understand what broke? May I close this?

Thanks, but it does not really indicate why it would fail on circleci.
