Open Container Format Progress Report

Follow Up from Open Container Initiative (formerly Project) Announcement of 6/22 written by Michael Crosby, Chief Maintainer of Docker, Inc. Approximately one month ago, we announced the creation of the Open Container Initiative*, under the auspices of the Linux Foundation for the express purpose of defining common specifications around container format and runtime.  Docker donated both our base container format and runtime, runC, and we began working with maintainers of AppC to create a common set of specifications. I’m happy to share that there has been a lot of progress in the past month. After the first few weeks of work for the OCF specification and runC most of the unanswered questions have either been solved or progress is being made on the GitHub repositories.  We are sprinting to get the first draft out to the community by the end Continue reading…

Today we’re happy to announce Docker 0.6.5. Don’t be fooled by the version number: this is a significant release! Think of it as a preparation for 0.7, which will be even more significant. In addition to numerous bug fixes, this release introduces container naming, links between containers, better host integration, and advanced port redirects. A big thank you to (in no particular order) to Paul Nasrat, Tianon Gravi, Edmund Wagner, Travis Cline, Gurjeet Singh, Justin Force, Johan Euphrosine, Ole Reifschneider, Will Rouesnel, Alex Larsson, Greg Thornton, Sven Dowideit, Scott Bessler, Todd Lunter, Vladimir Rutsky, Nicolas Dudebout, Nicolas Dudebout, Roger Peppe, Jerome Petazzoni for your contributions. Not bad for a minor release! (sorry if we forgot anyone).

Introducing the Dockerfile tutorial

Dockerfiles can be viewed as an image representation. They provide a simple syntax for building images and they are a great way to automate and script the images creation. If you are really serious about Docker, you should master the Dockerfile syntax. To help you learn the Dockerfile syntax, we did put together a very easy to follow tutorial. In the next couple of months we will release several levels, one  at a time, so you could master the Dockerfile syntax quickly, instruction by instruction. At the end of each level you will find tests to check your knowledge. Ready? Start  Level 0
