5 Kokki Infrastructure Automation Configuration Management Part of Provisioning Library and simple command line tool Currently no client/server component Can use GitHub in place of client/server Alternative to Puppet/Chef/Cfengine Implemented in Python Creative Arts & Technologies

6 Kokki Terms Kokki is a configuration management framework. It can be used standalone or as a part of a more complex system. It means cook in Finnish Environment: Execution environment Resource: Describes a file, service, package, etc.. Provider: Knows how to execute a resource Kitchen: Container for cookbooks Cookbook: Container for recipes and libraries Recipe: group of resource definitions Library: utility methods, resources, and providers Creative Arts & Technologies

7 Kokki Quick Example from kokki import * with Environment() as env: Package("vim", action="upgrade") File("/etc/hosts", owner = "root", group = "root", content = " localhost\n" " broadcasthost\n" "::1 localhost\n" "fe80::1%lo0 localhost\n") env.run() Creative Arts & Technologies

8 Kokki++ Multiconf Multiconf is a framework for describing complex environments using Python. Why It started from a simple need of continuous deployment of Java EE projects. Using a bunch of Python scripts, and a bunch of plain text property files. When number of property files increased number of scripts increased, too Out of this dilemma Multiconf was born Creative Arts & Technologies

9 Multiconf How Imagine a project, using multiple servers like Tomcat, Jetty, JBoss, Glassfish or Weblogic. You are going to use database connections and four environments: Local (for developer's local machine) Dev Test Prod Project configuration will be similar on different environments, but something will be different (databases and ports, for example) Creative Arts & Technologies

10 Multiconf (2) What Multiconf is not Multiconf itself doesn't know how to create environments. Multiconf doesn't know how to create any of the environment's components Multiconf has nothing to execute Perfect match for a system such as Kokki Same language Pluggable recipes and Libraries make Kokki open to such Extensions What Multiconf is Multiconf allows you to define your software stack and get early warning that something within your definition is wrong. Other tools use YAML or JSON to define settings of the components, but then you need something to validate those settings. Multiconf is both - definition and validation Creative Arts & Technologies

11 Multiconf JSF Example from javax_faces import ProjectStage from valid_envs import local, dev, test, pp, prod def jsf_stages(): with ProjectStage() as ps: ps.name(local= Development, dev= Development, test= UnitTest, pp= SystemTest, prod= Production ) Creative Arts & Technologies

12 PyDev PyDev is a product of Appcelerator, a platform and services company that is enabling Web developers to build cross-platform / native applications for Mobile, Tablet and Desktop platforms Winner of 2011 Eclipse Award for Best Developer Tool Appcelerator also makes Aptana Studio and Titanium Studio, Eclipse-based IDEs targeting Web and Mobile platforms Creative Arts & Technologies
