Docker support is a new feature to enable more complex jobs where you need to control the entire stack, for instance, maybe you need imagemagick installed on the core machine, or ghostscript.

It also allows you to test your workers locally before uploading: http://blog.iron.io/2015/03/the-new-ironworker-development-workflow.html http://blog.iron.io/2015/03/the-new-ironworker-development-w....

Or node: https://github.com/iron-io/dockerworker/blob/master/node/hello.js https://github.com/iron-io/dockerworker/blob/master/node/hel...
