Wercker has for some time provided a number of
built-in steps that make it easy to build a Docker image, test
it, and then push it to an image registry, all in a Wercker
pipeline.
However sometimes your Wercker pipelines need to be able to
access a Docker daemon directly. You might need to use the full
power of the docker command, or you might need to use
build tools that access the docker daemon.
We're therefore very pleased to announce that you can now give
your Wercker...
