Deploy OpenStack IceHouse like a Boss!

This little snippet of ~200 lines of YAML is the exact OpenStack that I'm deploying tonight, at the OpenStack Austin Meetup.

Anyone with a working Juju and MAAS setup, and 7 registered servers should be able to deploy this same OpenStack setup, in about 12 minutes, with a single command.

$ wget
$ juju-deployer -c icehouseOB.yaml

Dream a little dream (in a dream within another dream) with me!

What would you say if I told you, that you could continuously upload your own Software-as-a-Service  (SaaS) web apps into an open source Platform-as-a-Service (PaaS) framework, running on top of an open source Infrastructure-as-a-Service (IaaS) cloud, deployed on an open source Metal-as-a-Service provisioning system, autonomically managed by an open source Orchestration-Service… right now, today?

“An idea is resilient. Highly contagious. Once an idea has taken hold of the brain it's almost impossible to eradicate.”

“Now, before you bother telling me it's impossible…”

“No, it's perfectly possible. It's just bloody difficult.” 

Perhaps something like this...

“How could I ever acquire enough detail to make them think this is reality?”

“Don’t you want to take a leap of faith???”
Sure, let's take a look!

Okay, this looks kinda neat, what is it?

This is an open source Java Spring web application, called Spring-Music, deployed as an app, running inside of Linux containers in CloudFoundry

Cloud Foundry?

CloudFoundry is an open source Platform-as-a-Service (PAAS) cloud, deployed into Linux virtual machine instances in OpenStack, by Juju.



OpenStack is an open source Infrastructure-as-a-Service (IAAS) cloud, deployed by Juju and Landscape on top of MAAS.

Juju is an open source Orchestration System that deploys and scales complex services across many public clouds, private clouds, and bare metal servers.



Landscape is a systems management tool that automates software installation, updates, and maintenance in both physical and virtual machines. Oh, and it too is deployed by Juju.

MAAS is an open source bare metal provisioning system, providing a cloud-like API to physical servers. Juju can deploy services to MAAS, as well as public and private clouds.

"Ready for the kick?"

If you recall these concepts of nesting cloud technologies...

These are real technologies, which exist today!

These are Software-as-a-Service  (SaaS) web apps served by an open source Platform-as-a-Service (PaaS) framework, running on top of an open source Infrastructure-as-a-Service (IaaS) cloud, deployed on an open source Metal-as-a-Service provisioning system, managed by an open source Orchestration-Service.

Spring Music, served by CloudFoundry, running on top of OpenStack, deployed on MAAS, managed by Juju and Landscape!

“The smallest seed of an idea can grow…”

Oh, and I won't leave you're not dreaming!

OpenStack Austin Meetup, with an Orange Box and Home Brew Beer!

In case you missed the recent Cloud Austin MeetUp, you have another chance to see the Ubuntu Orange Box live and in action here in Austin!

This time, we're at the OpenStack Austin MeetUp, next Wednesday, September 10, 2014, at 6:30pm at Tech Ranch Austin, 9111 Jollyville Rd #100, Austin, TX!

If you join us, you'll witness all of OpenStack Ice House, deployed in minutes to real hardware. Not an all-in-one DevStack; not a minimum viable set of components.  Real, rich, production-quality OpenStack!  Ceilometer, Ceph, Cinder, Glance, Heat, Horizon, Keystone, MongoDB, MySQL, Nova, NTP, Quantum, and RabbitMQ -- intelligently orchestrated and rapidly scaled across 10 physical servers sitting right up front on the podium.  Of course, we'll go under the hood and look at how all of this comes together on the fabulous Ubuntu Orange Box.

And like any good open source software developer, I generally like to make things myself, and share them with others.  In that spirit, I'll also bring a couple of growlers of my own home brewed beer, Ubrewtu ;-)  Free as in beer, of course!

Call for Testing: Docker 1.0.1 in Ubuntu 14.04 LTS (Trusty)

Docker 1.0.1 is available for testing, in Ubuntu 14.04 LTS!

Docker 1.0.1 has landed in the trusty-proposed archive, which we hope to SRU to trusty-updates very soon.  We would love to have your testing feedback, to ensure both upgrades from Docker 0.9.1, as well as new installs of Docker 1.0.1 behave well, and are of the highest quality you have come to expect from Ubuntu's LTS  (Long Term Stable) releases!  Please file any bugs or issues here.

Moreover, this new version of the Docker package now installs the Docker binary to /usr/bin/docker, rather than /usr/bin/ in previous versions. This should help Ubuntu's Docker package more closely match the wealth of documentation and examples available from our friends upstream.

A big thanks to Paul Tagliamonte, James Page, Nick Stinemates, Tianon Gravi, and Ryan Harper for their help upstream in Debian and in Ubuntu to get this package updated in Trusty!  Also, it's probably worth mentioning that we're targeting Docker 1.1.2 (or perhaps 1.2.0) for Ubuntu 14.10 (Utopic), which will release on October 23, 2014.

Here are a few commands that might help your testing...

Check What Candidate Versions are Available

$ sudo apt-get update
$ apt-cache show | grep ^Version:

If that shows 0.9.1~dfsg1-2 (as it should), then you need to enable the trusty-proposed pocket.

$ echo "deb trusty-proposed universe" | sudo tee -a /etc/apt/sources.list
$ sudo apt-get update
$ apt-cache show | grep ^Version:

And now you should see the new version, 1.0.1~dfsg1-0ubuntu1~ubuntu0.14.04.1, available (probably in addition to 1.0.1~dfsg1-0ubuntu1~ubuntu0.14.04.1).


Check if you already have Docker installed, using:

$ dpkg -l

If so, you can simply upgrade.

$ sudo apt-get upgrade

And now, you can check your Docker version:

$ sudo dpkg -l | grep -m1 ^ii | awk '{print $3}'

New Installations

You can simply install the new package with:

$ sudo apt-get install

And ensure that you're on the latest version with:

$ dpkg -l | grep -m1 ^ii | awk '{print $3}'

Running Docker

If you're already a Docker user, you probably don't need these instructions.  But in case you're reading this, and trying Docker for the first time, here's the briefest of quick start guides :-)

$ sudo docker pull ubuntu
$ sudo docker run -i -t ubuntu /bin/bash

And now you're running a bash shell inside of an Ubuntu Docker container.  And only bash!

root@1728ffd1d47b:/# ps -ef
root         1     0  0 13:42 ?        00:00:00 /bin/bash
root         8     1  0 13:43 ?        00:00:00 ps -ef

If you want to do something more interesting in Docker, well, that's whole other post ;-)

(Re-)Introducing JeOS -- Just Enough OS, aka Ubuntu Core

Lean.  Agile.  Svelte.  Lithe.  Free.

That's how we roll our operating systems in this modern, bountiful era of broadly deployed virtual machines, densely packed with system containers.

Linux, and more generally free software, is a natural fit in this model where massive scale is the norm.  And particularly Ubuntu (with its solid Debian base), is perfectly suited to this brave new world.

Introduced in Ubuntu 8.04 LTS (Hardy) -- November 19, 2007, in fact -- JeOS (pronounced, "juice") was the first of its kind.  An absolutely bare minimal variant of the Ubuntu Server, tailored to perfection for virtual machines and appliances.  Just enough OS.

Taken aback, I overheard a technical executive at a Fortune 50 company say this week:
"What ever happened to that Ubuntu JeOS thing?  We keep looking at CoreOS and Atomic, but what we really want is just a bare minimal Ubuntu server."
Somehow, somewhere along the line, an important message a got lost.  I hope we can correct that now...

JeOS has been here all along, in fact.  You've been able to deploy a daily, minimal Ubuntu image, all day, every single day for most of the the last decade.  Sure, it changed names to Ubuntu Core along the way, but it's still the same sleek little beloved ubuntu-minimal distribution.

"How minimal?", you ask...

63 MB compressed, to be precise.

Did you get that?

That's 63 MB, including a package management system, with one-line, apt-get access to over 30,000 freely available packages across the Ubuntu universe.

That's pretty darn small.  Much smaller than say, 165 MB or 268 MB (which, to be fair, includes a bit more of an operating system -- much closer to say the standard Ubuntu Cloud Image, which is a 176 MB root tarball, or with kernel at 243 MB).

"How useful could such a small image actually be, in practice?", you might ask...

Ask any Docker user, for starters.  Docker's base Ubuntu image has been downloaded over 775,260 to date.  And this image is built directly from the Ubuntu Core amd64 tarball.

Oh, and guess what else?  Ubuntu Core is available for more than just the amd64 architecture!  It's also available for i386, armhf, arm64, powerpc, and ppc64el.  Which is pretty cool, particularly for embedded systems.

So next time you're looking for just enough operating system, just look to the core.  Ubuntu Core.  There is truly no better starting point ;-)

Learn Byobu in 10 minutes while listening to Mozart

If you're interested in learning how to more effectively use your terminal as your integrated devops environment, consider taking 10 minutes and watching this video while enjoying the finale of Mozart's Symphony No. 40Allegro Assai (part of which is rumored to have inspired Beethoven's 5th).

I'm often asked for a quick-start guide, to using Byobu effectively.  This wiki page is a decent start, as is the manpage, and the various links on the upstream website.  But it seems that some of the past screencast videos have had the longest lasting impressions to Byobu users over the years.

I was on a long, international flight from Munich to Newark this past Saturday with a bit of time on my hands, and I cobbled together this instructional video.    That recent international trip to Nuremberg inspired me to rediscover Mozart, and I particularly like this piece, which Mozart wrote in 1788, but sadly never heard performed.  You can hear it now, and learn how to be more efficient in command line environments along the way :-)

Ubuntu OpenStack on an Orange Box, Live Demo at the Cloud Austin Meetup, August 19th

I hope you'll join me at Rackspace on Tuesday, August 19, 2014, at the Cloud Austin Meetup, at 6pm, where I'll use our spectacular Orange Box to deploy Hadoop, scale it up, run a terasort, destroy it, deploy OpenStack, launch instances, and destroy it too.  I'll talk about the hardware (the Orange Box, Intel NUCs, Managed VLAN switch), as well as the software (Ubuntu, OpenStack, MAAS, Juju, Hadoop) that makes all of this work in 30 minutes or less!

Be sure to RSVP, as space is limited.
