Openshift for Developers – Graham Dumpleton, Grant Shipley – O’Reilly

A quick, hand-holding introduction to a complex platform, useful to get an idea of what it has to offer without getting lost in the wealth of documentation and blog posts available on the web.
However, after a year and a half, it could do with a new edition: the all-in-one VM image has been replaced by the Minishift tool, some application pages have changed and at least one exercise doesn’t work any more. Still worth reading, nonetheless.
