Testing Nulecule on Debian

Testing Nulecule on Debian

Unless you’ve recently returned from a sabbatical year in a remote monastery with no internet, you know that Containers have arrived, and it’s a whole new world.

I’ll save you five minutes of reading, and 90 minutes of watching Disney’s Alladin and assume you know about containers. If not, take a look at Docker, rkt and the Open Container Project. For bonus points, watch How Docker Didn’t Invent Containers from the First Docker Meetup in my adopted hometown of Brno, Czech Republic. When you’re done singing the fantastic Disney songs, come back. I’ll wait.

Report on the Container Keynote Panel from LinuxCon EU 2015

At LinuxCon Europe 2015 from 5-7 October, 2015 in Dublin, Ireland. Project Atomic’s Joe Brockmeier moderated a panel discussion between Tom Barlow from Docker, Sebastien Goasguen of Citrix, and Brandon Philips from CoreOS about containers.

As you may know, the technology underlying containers is not new and that a big part of the innovation provided by Docker and others is essentially an easier way to package and access this technology. However, there are key questions ahead as the technology continues to mature and transcend the it’s just packaging idea. I didn’t transcribe the entire session, but I wanted to call out a few of the exchanges and how they affect various roles.

    • VARIANT="Atomic Developer Bundle (ADB)"
    • VARIANT_ID="adb"
    • VARIANT_VERSION="1.6.0"
  • Updated Documentation, a new Maintainer and more

The ADB provides a container development ecosystem that ensures that developers are able to work with Linux containers even if their base operating system does not support it.

vagrant-service-manager Plugin Version 0.0.3 Released

Version 0.0.3 of the vagrant-service-manager plugin has been released by Project Atomic.

The vagrant-service-manager plugin works in conjunction with the Atomic Developer Bundle (ADB) to provide a Linux container development environment. The plugin is used to display the configuration information of services present in ADB. This plugin replaces the previously released vagrant-adbinfo plugin.

The plugin displays the configuration details for the Docker and other container-related services running inside of the ADB. This information can be used by a CLI client, such as docker or oc, or by an IDE, such as Eclipse, to interact with the ADB.
