Introduction
A bit of history
What is buildout and what can I do with it?
Buildout basics and examples

A bit of history
Buildout originated from the Zope/Plone community
Setting up an application deployment was repetitive and tedious
There is a need for creating repeatable DTAP deployments

What is buildout
Support for creating application deployments
Assembling applications from multiple parts, Python or otherwise
An application may actually contain multiple programs, processes, and configuration settings

What can I do with buildout
Deploy DTAP* environments with one buildout
It's repeatable and reusable
* Development, Testing, Acceptance, Production

Simple buildout config [buildout] develop = src/hello parts = hello-buildout [hello-buildout] recipe = zc.recipe.egg interpreter = py eggs = hello

Multiple configuration files [buildout] extends = buildout-base.cfg supervisor.cfg pound.cfg prd-settings.cfg prd-version.cfg parts += instance0 ...

Variable substitutions [cluster] int-ip = 192.168.10.1 supervisor-port = 38080 [supervisor] recipe = collective.recipe.supervisor port = ${cluster:int-ip}:${cluster:supervisor-port} serverurl = http://${cluster:int-ip}:${cluster:supervisor-port} programs = 20 instance ${instance:location}/bin/runzope ${instance:location} true 80 pound ${buildout:directory}/bin/poundrun

Buildout recipes zc.recipe.egg plone.recipe.command zc.recipe.cmmi collective.recipe.patch collective.recipe.supervisor gocept.nginx mr.developer

Example buildout config [buildout] parts = pyramid eggs = ZopeSkel extensions = mr.developer sources = sources auto-checkout = opsbqueue gw20e.forms [sources] opsbqueue = svn https://svn.gw20e.com/oosterpoort/eggs/opsbqueue gw20e.forms = svn https://svn.plone.org/svn/collective/gw20e.forms/trunk [pyramid] recipe = zc.recipe.egg interpreter = py eggs = pyramid opsbqueue gw20e.forms

GW20e default buildout

Running buildout ~/buildout$ python bootstrap.py ~/buildout$ ./bin/buildout

Wrapping up
Use buildout deploying applications in complex environments
Powerful buildout recipes
Include non-Python components
Write once, deploy often!
