Ubuntu Cloud Infrastructure → Ubuntu Oneiric Ocelot (11.10)

Build your infrastructure as a service public or private cloud

● Based on OpenStack● Supporting KVM, Xen & LXC hypervisors● All components can be made highly

Orchestra


Ubuntu Orchestra

Install Orcherstra on your first server

Orchestra Infrastructure Server


Ubuntu Orchestra

Associate profiles with MAC addresses via the web or API interface



Ubuntu Orchestra

Turn on your hardware, the deployment happens, your infrastructure is ready!



Ubuntu Orchestra

Bare metal deployment from the Ubuntu Installer

● Zero touch deployment of complex workloads

● Configuration management● Customizable

Components● Cobbler● Fact database● Cloud-Init● Pluggable management tools

(Juju as default)



Installing Orcherstra

> sudo apt- get install ubuntu- orchestra- server


Installing Orcherstra


Installing Orchestra


Orchestra ready

● Latest Ubuntu ISO is downloaded● Package repositories are setup● PXE, TFTP, DHCP and Cobbler are ready

–> Let's define some servers


Declaring servers for Orchestra

sudo cobbler system add \

JujuDevops Distilled


What is DevOps?

● Rate of agile development and deployment requires deeper interaction between teams

● A melding of development, deployment, and QA principles, methods, and practices

● Fills the gap between developers and system administrators


What drives DevOps?

● Speed of the deployment

● Continuous Integration, Automated Testing, etc.

● Fast change vs. Stability


What does DevOps “deliver”?

● Fast repeatable server setup, consistent environment

● Abstract ops tasks to empower devs

● Smaller deployments empower ops

● Repeatable processes that let you scale out quickly


You've got the tools already

● Hardware● Virtualization● Platform (OS) ● Configuration Management

… need to tie that together into something whole.

Juju, DevOps Distilled

● Reuse existing deployment charms in an openly-accessible repository of shared expertise

● Reproduce deployments for test and staging purposes

● Rapid deployment of your dependencies for development purposes

● Compose whole systems from individual application components and describe the entire deployment

● Explicit control over deployment, configuration and upgrade options

● See what’s deployed and track usage in the cloud

● Create and share charms for new applications

● Monitor, scale, shrink and adjust deployment parameters in real time

● Explicitly connect different components and maintain those relationships over time

● Collaborate with developers on the exact deployment and upgrade processes

● Get more done: implement decisions immediately regardless of infrastructure scale

Juju's Charms

● Charms are a shareable, re-usable, and repeatable expressions of DevOps best practices.

● You can use them unmodified, or easily change and connect them to fit your needs.

● Deploying a formula is similar to installing a package on Ubuntu: ask for it and it’s there, remove it and it’s completely gone.


Juju is a community of DevOps expertise.

● Most of the application you want will be available in Juju.

● Juju provides direct and free access to a DevOps community-contributed collection of formulas


Juju provides service orchestration

● Juju focuses on managing the service units you need to deliver a single solution, above simply configuring the machines or cloud instances needed to run them.

● Charms developed, tested, and deployed on your own hardware will operate the same in an EC2 API compatible cloud, including OpenStack.


Juju is intelligent

● Juju exposes re-usable service units and well-defined interfaces that allow you to quickly and organically adjust and scale solutions without repeating yourself.


Juju is Easy

● There’s no need to learn a domain specific language (DSL) to use Juju or create formulas. You can be up and running with your own formula in minutes


Juju's internals


Juju

Juju treats individual services as atoms that are described as charms and can be instantiated one or many times.

Juju

Each charm (or atom) define dependencies and/or provides.

Multiple charms can provide the same service and can be easily switched.

Varnish


Juju

Juju maintains the relations between the services so that you don't need to care about the elasticity of your environment.

Relations are to charms what bounds are to atoms.

Services are loosely coupled but highly cohesive.

Juju Relation


Juju

Juju delivers service focused management through their life-cycle

● Offers the same simple rules to components of you infra as we do already for packages on your servers: dependencies, provides

● Adds the notion of dynamic relations between components

● To provide you with simple automated elasticity that is easy to expand

● Working on your bare metal servers (through Orchestra*) as easily as on your favourite clouds (AWS, OpenStack*, ...)

Deploying OpenStack with Juju


Back to the Orchestra server

● > sudo apt- get install juju

● > sudo mkdir - p ~/.juju

● > sudo vi ~/.ensemble/environments.yaml

juju: environments

environments:

orchestra:

type: orchestra

# Specify the orchestra server (santol's IP address)

orchestra- server: 10.55.55.7

# Specify storage. In this case we are using webdav installed by orchestra.

storage- url: http://10.55.55.7/webdav

# Specify cobbler's usr/pass

orchestra- user: cobbler

orchestra- pass: cobbler

admin- secret: fooooo

# Mangement classes

acquired- mgmt- class: orchestra- juju- acquired

available- mgmt- class: orchestra- juju- available


Deploying OpenStak

● > juju bootstrap

● > juju deploy mysql - - placement=local

● > juju deploy rabbitmq - - placement=local

● > juju deploy –config=~/formulas/openstack.yaml nova- cloud- controller

● > juju add- relation nova- cloud- controller rabbitmq

● > juju add- relation nova- cloud- controller mysql

● > juju deploy –config=~/formulas/openstack.yaml glance

● > juju add- relation glance mysql

● > juju add- relation glance:image- service nova- cloud- controller:image- service

● > juju deploy - - config=~/formulas/openstack.yaml - - repository= p̀wd ̀nova- compute

● > juju add- relation nova- compute rabbitmq

● > juju add- relation nova- compute mysql

● > juju add- relation nova- cloud- controller:nova- network nova- compute:nova- network

● > juju add- relation glance:image- service nova- compute:image- service


Scaling OpenStack

● > juju add-unit nova-compute

or

● > juju add-unit nova-cloud-controller


OpenStack is now in action !
