On Monday August 26th, VMware announced the general availability of their vCloud Hybrid Service. This service, initially opened back in May to a restricted set of early adopters provides VMware customers with a means of being able to easily bring their workloads out of their own datacentres and into to the cloud.

For many customers this is exactly what they want – they may have been wanting to move some of their workloads off premise but found the prospect of switching to a full blown public cloud provider a scary prospect. vCHS offers them a great way to move workloads to the cloud without having to worry about migrating to new technologies, api compatibility or sourcing a new vendor. At Canonical we have a vision of complete workload portability across any public or private cloud. Sure, it is a requirement that the workloads run on Ubuntu but Ubuntu’s ubiquity in cloud is close to making this a reality and with our growth in usage for scale out workloads such as delivery of online infrastructure far outstripping that of other Linux platforms, it seems that end users don’t have a problem with it. It certainly seems that with our engagements around OpenStack, Nicira and vCHS, VMware believe in the ubiquity of Ubuntu in cloud. Combined with VMware’s ubiquity in the enterprise, between the 2 of us we are going to do some great things.

We are pleased to announce a seriously good addition to the our product team: Ratnadeep (Deep) Bhattacharjee. Deep joins Canonical as Director of Cloud Product Management from VMware where he led its Cloud Infrastructure Platform effort and has a solid understanding of customer needs as they continue to move to virtual and cloud infrastructure.

Ubuntu has fast become the operating system of choice for cloud computing and Ubuntu is the most popular platform for OpenStack. With Deep’s direction, we plan to continue to lead Ubuntu OpenStack into enterprises, carriers and service providers looking for new ways to deliver next generation infrastructure without the ‘enterprise’ price tag and lock in. He will also be key in building out our great integration story with VMWare to help customers who will run heterogeneous environments. Welcome Deep!

I recently gave an introduction to the CloudFoundry Client application (vmc),  which is already in Ubuntu 11.10's Universe archive.

Here, I'd like to introduce the far more interesting server piece -- how to run the CloudFoundry Server, on top of Ubuntu 11.10!  As far as I'm aware, this is the most complete PaaS solution we've made available on top of Ubuntu Servers, to date.

A big thanks to the VMWare CloudFoundry Team who has been helping us along with the deployment instructions.  Also, all of the packaging credit goes straight to Brian Thomason, Juan Negron, and Marc Cluet.

For testing purposes, I'm going to run this in Amazon's EC2 Cloud.  I'll need a somewhat larger instance to handle all the services and dependencies (ie, Java) required by the platform.  I find an m1.large seems to work pretty well, for $0.34/hour.  I'm using the Oneiric (Ubuntu 11.10) AMI's listed at http://uec-images.ubuntu.com/oneiric/current/.

Installation

To install CloudFoundry Server, add the PPA, update, and install:

sudo apt-add-repository ppa:cloudfoundry/ppa

sudo apt-get update
sudo apt-get install cloudfoundry-server


During the installation, there are a couple of debconf prompts, including:
  • a mysql password
    • required for configuration of the MySQL database (enter twice)
All in all, the install took me less than 7 minutes!

Next, install the client tools, either on your local system, or even on the server, so that we can test our server:

sudo apt-get install cloudfoundry-client


Configuration

Now, you'll need to target your vmc client against your installed server, rather than CloudFoundry.com, as I demonstrated in my last post.

In production, you're going to need access to a wildcard based DNS server, either your own, or a DynDNS service.  If you have a DynDNS.com standard account ($30/year), CloudFoundry actually supports dynamically adding DNS entries for your applications.  We've added debconf hooks in the cloudfoundry-server Ubuntu packaging to set this up for you.  So if you have a paid DynDNS account, just sudo dpkg-reconfigure cloudfoundry-server.

For this example, though, we're going to take the poor man's approach, and just edit our /etc/hosts file, BOTH locally on our laptop and on our CloudFoundry server.

First, look up your server's external IP address.  If you're running Byobu in EC2, it'll be the lower right corner.

Otherwise, grab your IPv4 address from the metadata service.

$ wget -q -O- http://169.254.169.254/latest/meta-data/public-ipv4

174.129.119.101

And you'll need to add an entry to your /etc/hosts for api.vcap.me, AND every application name you deploy.  Make sure you do this both on your laptop, and the server!  Our test application here will be called testing123. Don't forget to change my IP address to yours ;-)

echo "174.129.119.101  api.vcap.me testing123.vcap.me" | sudo tee -a /etc/hosts


Target

Now, let's target our vmc client at our vcap (CloudFoundry) server:

$ vmc target api.vcap.me

Succesfully targeted to [http://api.vcap.me]

Adding Users

And add a user.

$ vmc add-user 

Email: kirkland@example.com
Password: ********
Verify Password: ********
Creating New User: OK
Successfully logged into [http://api.vcap.me]

Logging In

Now we can login.

$ vmc login 

Email: kirkland@example.com
Password: ********
Successfully logged into [http://api.vcap.me]

Deploying an Application


At this point, you can jump over to my last post in the vmc client tool for a more comprehensive set of examples.  I'll just give one very simple one here, the Ruby/Sinatra helloworld + environment example.

Go to the examples directory, find an example, and push!

$ cd /usr/share/doc/ruby-vmc/examples/ruby/hello_env

$ vmc push
Would you like to deploy from the current directory? [Yn]: y
Application Name: testing123
Application Deployed URL: 'testing123.vcap.me'?
Detected a Sinatra Application, is this correct? [Yn]: y
Memory Reservation [Default:128M] (64M, 128M, 256M, 512M, 1G or 2G)
Creating Application: OK
Would you like to bind any services to 'testing123'? [yN]: n
Uploading Application:
  Checking for available resources: OK
  Packing application: OK
  Uploading (0K): OK
Push Status: OK
Staging Application: OK
Starting Application: OK

Again, make absolutely sure that you edit your local /etc/hosts and add the testing123.vcap.me to the right IP address, and then just point a browser to http://testing123.vcap.me/


And there you have it!  An application pushed, and running on your CloudFoundry Server  -- Ubuntu's first packaged PaaS!

What's Next?

So the above setup is a package-based, all-in-one PaaS.  That's perhaps useful for your first CloudFoundry Server, and your initial experimentation.  But a production PaaS will probably involve multiple, decoupled servers, with clustered databases, highly available storage, and enterprise grade networking.

The Team is hard at work breaking CloudFoundry down to its fundamental components and creating a set of Ensemble formulas for deploying CloudFoundry itself as a scalable service.  Look for more news on that front very soon!

In the meantime, try the packages at ppa:cloudfoundry/ppa (or even the daily builds at ppa:cloudfoundry/daily) and let us know what you think!
