This article is cross-posted on Docker's blog as well.

There is a design pattern, occasionally found in nature, when some of the most elegant and impressive solutions often seem so intuitive, in retrospect.



For me, Docker is just that sort of game changing, hyper-innovative technology, that, at its core,  somehow seems straightforward, beautiful, and obvious.



Linux containers, repositories of popular base images, snapshots using modern copy-on-write filesystem features.  Brilliant, yet so simple.  Docker.io for the win!


I clearly recall nine long months ago, intrigued by a fervor of HackerNews excitement pulsing around a nascent Docker technology.  I followed a set of instructions on a very well designed and tastefully manicured web page, in order to launch my first Docker container.  Something like: start with Ubuntu 13.04, downgrade the kernel, reboot, add an out-of-band package repository, install an oddly named package, import some images, perhaps debug or ignore some errors, and then launch.  In few moments, I could clearly see the beginnings of a brave new world of lightning fast, cleanly managed, incrementally saved, highly dense, operating system containers.

Ubuntu inside of Ubuntu, Inception style.  So.  Much.  Potential.



Fast forward to today -- April 18, 2014 -- and the combination of Docker and Ubuntu 14.04 LTS has raised the bar, introducing a new echelon of usability and convenience, and coupled with the trust and track record of enterprise grade Long Term Support from Canonical and the Ubuntu community.
Big thanks, by the way, to Paul Tagliamonte, upstream Debian packager of Docker.io, as well as all of the early testers and users of Docker during the Ubuntu development cycle.
Docker is now officially in Ubuntu.  That makes Ubuntu 14.04 LTS the first enterprise grade Linux distribution to ship with Docker natively packaged, continuously tested, and instantly installable.  Millions of Ubuntu servers are now never more than three commands away from launching or managing Linux container sandboxes, thanks to Docker.


sudo apt-get install docker.io
sudo docker.io pull ubuntu
sudo docker.io run -i -t ubuntu /bin/bash


And after that last command, Ubuntu is now running within Docker, inside of a Linux container.

Brilliant.

Simple.

Elegant.

User friendly.

Just the way we've been doing things in Ubuntu for nearly a decade. Thanks to our friends at Docker.io!


Cheers,

In about an hour, I have the distinct honor to address a room full of federal sector security researchers and scientists at the US Department of Energy's Oak Ridge National Labs, within the Cyber and Information Security Research Conference.

I'm delighted to share with you the slide deck I have prepared for this presentation.  You can download a PDF here.

To a great extent, I have simply reformatted the excellent Ubuntu Security Features wiki page our esteemed Ubuntu Security Team maintains, into a format by which I can deliver as a presentation.

Hopefully you'll learn something!  I certainly did, as I researched and built this presentation ;-)
On a related security note, it's probably worth mentioning that Canonical's IS team have updated all SSL services with patched OpenSSL from the Ubuntu security archive, and have restarted all relevant services (using Landscape, for the win), against the Heartbleed vulnerability. I will release an updated pollinate package in a few minutes, to ship the new public key for entropy.ubuntu.com.



Stay safe,
Dustin

Today we announced a collaborative support and engineering agreement with Dell.  As part of this agreement Canonical will add Dell 11G & 12G PowerEdge models to the Ubuntu Server 12.04 LTS Certification List and Dell will add Ubuntu Server to its Linux OS Support Matrix.

In May 2012, Dell launched the OpenStack Cloud Reference Architecture using Ubuntu 12.04 LTS on select PowerEdge-C series servers. Today’s announcement expands upon that offering by combining the benefits of Ubuntu Server Certification, Ubuntu Advantage enterprise support, and Dell Hardware ProSupport across the PowerEdge line.

Dell customers can now deploy with confidence when purchasing Dell PowerEdge servers with Dell Hardware ProSupport and Ubuntu Advantage.  When these customers call into Dell, their service tag numbers will be entitled with ProSupport and Ubuntu Advantage, which will create a seamless support experience via the collaborative Dell and Canonical support and engineering relationship.

In preparation for this announcement, Canonical engineers worked with Dell to enable and validate Ubuntu Server running on Dell PowerEdge Servers.  This work resulted in improved Ubuntu Server on Dell PowerEdge support for PCIe SSD (solid state drives), 4K-block drives, EFI booting, Web Services Management, consistent network device naming, and PERC (PowerEdge RAID Controllers).

Dell hardware systems management can be done out-of-band via ipmi, iDRAC, and the Lifecycle Controller.  Dell OMSA Ubuntu packages are also available but it is recommended to use the supported out-of-band systems management tools.  Dell TechCenter is a good resource for additional technical information about running Ubuntu Server on Dell PowerEdge servers.

If you are interested in purchasing Ubuntu Advantage for your Dell PowerEdge servers, please contact the Dell Solutions team at Canonical.  If your business is already using or thinking about using a supported Ubuntu Server infrastructure in your data-center then be sure to fill out the annual Ubuntu Server and Cloud Survey to provide additional feedback.

Have you ever wanted to experiment with the latest cutting-edge cloud software, but run it on the same long-term support release of Ubuntu that you have all your other apps and services working on?

Well, now you can. Today, Canonical has released the Cloud Archive for Ubuntu 12.04 LTS Server, an online software repository from which administrators can download the latest versions of OpenStack, for use with the latest long-term support (LTS) release of Ubuntu. This is hugely significant step for OpenStack users, because it means they can now access the latest OpenStack releases and betas on a stable and supported platform that is certified with many of the leading server vendors.

As many people know, the tradition of Ubuntu Server is to release every six months, with every fourth release (or two years) being a Long Term Support (LTS) version supported for five years. The interim releases are supported for 18 months. This generally works well: businesses that require a solid infrastructure for a long period of time normally use the most recent LTS, rather than upgrading every 6-18 months.

Users often find that this predictable release schedule allows all areas of a workload lifecycle (from requirement, design, develop to deploy) to work well.  However, sometimes a key piece of the stack is needed. This leaves users in a quandary: jump to a later (non-LTS) Ubuntu release, or find something that helps solve the problem, building on the LTS release.

One way to try and address this problem is via backports. Over the years, there has been attempts to use the Ubuntu Backports repository, and also ‘blessed’ PPA’s (Personal Package Archives) or private in-house archives to provide access to later technologies backported from upstream.

With OpenStack, which underpins Ubuntu Cloud Infrastructure, we needed to think about how we would deliver the new OpenStack releases on 12.04 LTS without backporting, as using the Backports Archive would restrict the number of versions we could support concurrently (unless we opted for multiple Backport archives). OpenStack made the early decision to implement their development processes around the Ubuntu development process and to follow our release cadence. This has helped OpenStack deliver features with pace and on a deadline but crucially, it has allowed us to put continuous integration testing in place to integrate and test OpenStack code as soon as it is committed.

So with OpenStack we are now building, integrating, testing and publishing all the OpenStack milestones and stable releases on 12.04 LTS. This is a departure from our previous policy but the process for updates getting into the Ubuntu Cloud Archive has been designed to closely align with the processes that the normal Ubuntu Archive would have for Stable Release Updates.

With a fast moving technology such as OpenStack, this is hugely significant, as we see many customers testing the milestones and building seed clouds with the latest code. All this helps us find bugs and improve the code for all – which can only be a good thing.

To get access to the Ubuntu Cloud archive, please add the following entries to your /etc/apt/sources.list:

 

/etc/apt/sources.list entries:

# Public -proposed archive mimicking the SRU process, packages should bake here for at least 7 days.

#  This is also where extended testing is performed

deb  http://ubuntu-cloud.archive.canonical.com/ubuntu precise-proposed/folsom main


# The primary updates archive that users should be using

deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/folsom main


# Upstream milestone archive, this example is pinned to Folsom-1 upstream, then an example of Folsom-2.

#   This, being a snapshot, will not receive further updates.

deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/folsom/snapshots/milestone-1 main

deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/folsom/snapshots/milestone-2 main

Ubuntu 12.04 LTS will be released to the world this Thursday and it’s going to be fantastic. We’ve known for quite a while that Ubuntu is not only beautiful, but also usable and robust for individuals and a great platform for app developers. Those traditions continue in 12.04, with the added bonus of long term support (LTS) promise. This release will be our fourth LTS release, a significant milestone by itself, but it will also be the first in which we offer special consideration of hardware refresh cycles on the desktop and fast-moving technology developments in the cloud.

Ubuntu 12.04 LTS  is the ideal platform for organisations looking for more cost-effective alternatives to traditional desktop computing. As enterprise moves to cloud-based apps and lighter, more mobile clients, the argument for moving beyond a Windows-only environment has never been stronger. Ubuntu delivers an intuitive, responsive and above all, productive desktop experience at a fraction of the cost of its competitors.

Ubuntu Server 12.04 LTS combines the world’s best open source server and cloud technologies with five years of hardware, security and maintenance updates, and of course the option of enterprise-grade commercial support. This combination of proven technologies, time-saving deployment tools and long-term support makes it a cost-effective platform for any workload from print and web serving to big data applications and the cloud.

With support guaranteed for five years, certification on a wide range of hardware and the option of enterprise-grade commercial services, Ubuntu is a proven, cost-effective enterprise platform that can be relied on for the long term for their desktop, server, and cloud needs.

On Thursday we expect to see the reliability, collaboration, freedom and yes, precision, that Ubuntu embodies delivered again, on time, and in style. I can’t wait.

On Wednesday Dell announced a comprehensive overview of its enterprise strategy. Significant in its announcement, was the addition of Ubuntu Enterprise Cloud (UEC) as an infrastructure solution, joining the proprietary offerings from VMWare and Microsoft. This is the first major offering of a true open source Cloud solution backed by a major corporate vendor.

Dell will offer a series of ‘blueprint’ configurations that have been optimised for different use cases  and scale. These will include PowerEdge-C hardware, UEC software and full technical support – you will be able to buy these straight from Dell or you can use the ‘blueprints’ as a base to create your own bespoke solution. The Dell team have great strength and experience here and will provide detailed guidance on all the ‘blueprint’ solutions, as well as enterprise class deployments.

Ubuntu Enterprise Cloud leads the Linux field with integration of cloud capabilities directly into the OS. UEC is based on Eucalyptus which builds on the de facto cloud API standards of Amazon EC2 and S3. The relationship between Canonical and Eucalyptus Systems ensures that you have one escalation path to resolve any issues with the OS or the cloud service. Offering the same APIs as the dominant public cloud offering, Amazon EC2, you can build your applications to run on either platform. The Dell solution will be based on Ubuntu 10.04 LTS – which is released on April 29th.

Behind the scenes we’ve worked with Dell’s DCS team for over six months to test and validate the integration of the cloud stack on their new PowerEdge-C series. Within the industry, the DCS team has an excellent reputation for full design, integration, installation anddeployment. It has been both challenging and exciting working to meet and exceed their expectations, a result of excellent cooperation between the Dell core team, our Cloud & Server team and Eucalyptus.
