body: <p>Prob something very obvious, just not to me. Automated builds in Docker are not triggered when I push to master branch on github. repo is at <a href="https://github.com/lukewendling/embed-map" rel="nofollow">https://github.com/lukewendling/embed-map</a> - Dockerfile at root of project. My build settings shown here: <a href="http://snag.gy/iGYs6.jpg" rel="nofollow">http://snag.gy/iGYs6.jpg</a></p>
