They are an excellent resource for both beginners and experienced developers. Docker can be a common interface between developers and operations personnel eliminating a source of friction. It also encourages the same image/binaries to be used at every step of the pipeline. Moreover, being able to deploy fully tested container without environment differences help to ensure that no errors are introduced in the build process. Another interesting feature of having software containers is that it is easy to spin out slave machines with the identical development setup.
