In a post on the Dartlang.org blog, software engineer Søren Gjesse reports Dart is now available as a set of ready-to-deploy Docker images: a base image with the Dart SDK, a runtime, and an application that features a simple HTTP server written in Dart. Google also offers a similar set of Docker images for Node.js, Python, and Go to be used with Google App Engine, but these Dart images can be used anywhere Docker is available.
This move hints at Dart's potential as more a server-side solution and less a client-side technology. Earlier notes about Dart discussed improvements in server performance, for instance. But Google's Go language has already made significant inroads with developers who are creating distributed and server-side applications, leaving less mind share for Dart to go around.
If developers have their pick of languages to create Docker-ized apps, they'll more likely go with an established winner than an upstart whose use case is open to question. Still, as far as Docker goes, it's encouraging to see the software container system used as a tool for the adoption of other developing technologies apart from itself.
