Docker: Yet Another Software Deployment Endeavor

Posted in Free/Libre Software at 8:25 am by Dr. Roy Schestowitz

Summary: Introduction to Docker, which comes from the group formerly known as “dotCloud”

THERE are many projects like Docker, but this one is different, or so they want us to believe.

Docker made its debut not too long ago, then making some formal announcements [1,2] and enjoying favourable coverage [3] as well as endorsement from the likes of Red Hat [4]. One pundit called it “an open source startup you need to know about” [5], Wired called it “The Future of Cloud Computing” [6] and another theme in coverage [7] was support for many GNU/Linux distributions out of the box [8].

Docker claims to build “lightweight, portable and self-sufficient containers from any application that run virtually anywhere: bare metal, virtualized, public cloud or private cloud.” The nebulous term “cloud” is not helpful here, so putting it aside for now, what we actually have here is a company formerly known as “dotCloud” approaching bloggers, seeking to generate buzz and hype over something that has been done before, under a different name. Since Docker is Free software (licensed under the Apache 2.0 license) it does deserve some attention. █

Docker, the popular container technology that, in theory, lets developers encapsulate their apps and run them on bare metal, virtualized and private or public cloud environments, now supports nearly all the major Linux distributions right out of the box.
