## Anatomy of a Wombat ### tl;dr Wombat is a collection of code that builds Chef configured golden images from packer templates that are then re-consumed by a Cloud service template such as CloudFormation or Google Deployment Manager. ### Design Goals * coordination without coordination * principle of least surprise * dynamic templates over static files * long build times, short deploy times ### A Stroll Down Architecture Lane The core of wombat is the binary `bin/wombat`. `wombat build -o BUILDER TEMPLATE` 1. Generate x509 certificates for the domain and ssh keys if there are none 2. Vendor cookbooks for template 3. Build Packer images for -o BUILDER (amazon-ebs|googlecompute) with included cookbooks * If the TEMPLATE argument is not provided it will execute against all templates in `./packer/` `wombat update lock` 1. Create/update wombat.lock based on most recent Packer logs `wombat update template` 1. Create cfn/gdm configuration from lock * If no argument is provided it will update _both_ lock and template `wombat deploy STACK` 1. Deploy cfn/gdm stack `wombat outputs STACK` 1. List outputs, specifically Workstation IPs `wombat delete STACK` 1. Delete stack
