This document describes a light-weight DevOps approach to managing Islandora digital repository installations using a single directory under version control. The approach uses Git submodules to manage dependencies like Drupal, Islandora and configuration files. Scripts are used to generate configuration files and push changes between developer, staging and production environments. Demonstrations include adding modules, updating configurations and creating new sites.

2. Technical Drivers
• Self-contained directory
• Easily replicate developer, staging and
production environments
• Track and contribute to upstream
development
• Put configuration under version control
• Support multi-site setup

3. One-directory Setup
• Extensive use of Git Submodules for Drupal,
Islandora, etc.
• Relative symbolic links within the directory
• Configuration files generated by scripts

4. Inside the Box (Source)
• Fedora Commons
• Drupal
• Islandora
• GSearch configuration
• Site-specific configuration, modules, themes

5. Inside the Box (Binaries)
• Tomcat
• Adore Djatoka
• SOLR
• FITS

6. Outside the Box
• Apache HTTPD
• MySQL RDBMS
• Java JVM
• ImageMagic
• Poppler Utils
• Ghostscript
• Tesseract

7. Git Submodules
• Adds a git repository inside another
• Top-level repository tracks the commit ID of
the submodule

8. Drupal Features
• Stores module dependancies, variables,
permission roles, etc.
• Updated by script-driven value substitutions

9. Demonstrations
• Adding a new Islandora module
• Pushing configurations to staging
• Keeping up-to-date (monitoring upstream)
• Creating a new site

10. To-Dos
• http://github.com/lyrasis/reposervice
• Continue to refactor out LYRASIS-specific
names, variables, etc.
• Refactor bin/reposervice-config out of bash
• Code a helper script for adding a submodule
• If there is interest, generalize and fork to
http://github.com/Islandora
