Intro

A demonstration using DevOps/CICD with the Rackspace APIs to stand up a simple web app reference stack.

Quickstart:

• install the python-heatclient Python package: 'pip install python-heatclient'
• setup your Heat API ENV variables via .bashrc
• run 'make' for a basic example
• read Makefile for examples/tests
• run 'heat/heatclient-test/test.py -h' for list of available commandline parameters

Notes

Unattended chef-client bootstrap install doc: http://docs.opscode.com/install_bootstrap.html#unattended-installs

Goals

• A demonstrative example of a simple web application stack. (Load balanced web servers fronted by Varnish and running Nginx/PHP, backend Mysql DB, Memcache and Cloud Files).
• The example stack will be spawned via basic web form user input for customization (branding, region, flavor, ssh keys, passwords, disk sizing etc.).

Tools

• Heat Orchestration Template(s)
• Chef
• Jenkins CI
• Github
• PHP, Python, Bash
• Glue and Duct Tape

Milestones

• Build a customized server using Heat and user-data
• Automate the build using shell scripts, Heat CLI and Make
• Create a Jenkins job to automatically build/test the project
• Build the Nginx/PHP-FHM server using Heat and user data
• Replace the user-data hackery with Chef bootstrapping
• Automate provisioning of the application infrastructure layer with Chef
• Configure automated deployment of a simple PHP app to the web server instance
• Build out the rest of the infrastructure using Heat (LB, Varnish, DB, Memcache)
• Web interface for kicking off the build with parameters for build time customization
• Replacing the shell scripts and Heat CLI with Python code using the Heat Python API
• Profit :-)
