Who’s a Magento developer? Who spends a significant
amount of his/her time dealing
with development/deployment
processes?
Who thinks he/she’s got it
figured out?
YOU...?

modman “connects” existing modules to the Magento core, but how do we manage them?

Composer
AOEpeople/composer-installers "replace": { "magento-hackathon/magento-composer-installer":"*" }
“inspired” by composer/installers
“magento-module” “magento-source”
handles package types
<?php namespace Aoepeople\ComposerInstallers; class MagentoInstaller extends BaseInstaller { protected $locations = array( 'module' => '.modman/{$name}/', 'source' => 'htdocs/' ); }
AOEpeople/composer-installers
• Fully compatible with magento-hackathon/magento-composer-installer
• Adds support for type “magento-source”
• Only puts packages into place
• Native modman script is used to deploy modules
• Wrapped in a simple installer script
AOEpeople/composer-installers
{ "minimum-stability":"dev", "require":{ "aoepeople/composer-installers": "*", "fbrnc/aoe_scheduler": "*", "fbrnc/aoe_cachecleaner": "*", "aoepeople/magento_enterprise": "1.13.1.0", "aoepeople/envsettingstool": "*" }, "config": { "bin-dir": "bin" } }

Deploy often!
No manual interaction!
no creating CMS blocks
no creating product attributes
no updating of any configuration settings!
no clearing the cache
no purging CDN or Reverse Proxy
content!
Details? High Performance Magento in the Cloud
Deployment Strategy
Deployment Pattern
Build Installation Deployment Provisioning
Build What is it?
A simple shell script. That’s it! No Ant, no Phing, no fancy PHP tool/framework
Where is it used?
In the build job of a Jenkins server
What does it need to know?
Where to get all the source code from
What does it do?
add metadata, composer, modman, minify, packaging, upload to S3
Provisioning What is it?
A couple of chef cookbooks. Run by AWS OpsWorks or Vagrant,…
Where is it used?
On the target servers
What does it need to know?
The role of the server (web server, devbox, Redis,…)
What does it do?
Installing and configuring web server, PHP, MySQL, Redis,…
Deployment What is it?
A simple shell script. Or the “deploy” chef cookbook Or EasyDeployWorkflows
Where is it used?
On the target servers
What does it need to know?
How to get the build and where to deploy it to
What does it do?
(Resetting the environment), getting the build, extracting it, managing release folders and symlinks, triggering installer, cleanup old releases
Installation What is it?
A simple shell script. Sometimes triggered inside “deploy” before_migrate.rb
Where is it used?
On the target servers, called from deployment step
What does it need to know?
What environment this is. Injected settings
What does it do?
Run modman, connect to shared directories, apply settings, trigger update scripts, customize cache prefix,
Deployment != Installation
doesn’t know anything about the app, except where to get it from
and where to put it
knows how to get the app up and running
Cache Invalidation
Cache Warming
add build number to id_prefix
