What is configuration? September 1, 2016 Page 4 | Configuration Management: A True Life Story
” In Drupal, configuration is the collection of admin settings that determine how the site functions, as opposed to the content of the site. https://www.drupal.org/docs/8/configuration-management Page 5 | Configuration Management: A True Life Story
Configuration vs. Content Configuration Content Content types Nodes Taxonomy vocabulary Taxonomy terms Menus Menu links Blocks Block content Media types Media Page 6 | Configuration Management: A True Life Story
Pantheon Workflow https://pantheon.io/docs/pantheon-workflow/#code-moves-up-content-moves-down Page 7 | Configuration Management: A True Life Story
Other types of configuration ● Fields ● Language settings ● Views ● System settings ● Display modes ● User roles ● Image styles ● Module settings Page 8 | Configuration Management: A True Life Story
Where is configuration stored? Page 9 | Configuration Management: A True Life Story
Configuration Storage: Database ● Active configuration ● Stored in a relational database ● Changes applied immediately ● Benefits: ○ Performance ○ Security Page 10 | Configuration Management: A True Life Story
Configuration Storage: Filesystem ● Staged configuration ● Stored on the filesystem as YAML files ● Changes applied by export or import ● Benefits: ○ Portability ○ Security Page 11 | Configuration Management: A True Life Story
Configuration Manager September 1, 2016 Page 12 | Configuration Management: A True Life Story
Configuration Manager ● ● ● Core module Import and export a single set of configuration to the filesystem ○ User Interface ○ Drush Install configuration from modules, profiles and themes ○ Required config ○ Optional config Page 13 | Configuration Management: A True Life Story

Configuration Manager: Workflow The Configuration Management module offers a linear workflow where each environment shares the same set of configuration. CONFIG SYNC LOCAL Page 15 | Configuration Management: A True Life Story DEV STAGE PROD
Configuration Split September 1, 2016 Page 16 | Configuration Management: A True Life Story
Configuration Split ● ● ● ● Contributed module Import and export multiple sets (splits) of configuration to the filesystem ○ User Interface ○ Drush Enable/disable modules or themes for different environments Store different configuration values for different environments ○ Complete Split / Blacklist ○ Conditional Split / Graylist Page 17 | Configuration Management: A True Life Story
Complete Split Page 18 | Configuration Management: A True Life Story
Conditional Split Page 19 | Configuration Management: A True Life Story
Configuration Split: Environment Workflow Creating configuration splits by environment allows developers to group sets of configuration that differ per environment (e.g. dev, test, prod). CONFIG SYNC LOCAL Page 20 | Configuration Management: A True Life Story DEV STAGE PROD
Configuration Split: Feature Workflow Creating configuration splits by features allows developers to turn individual features (e.g. modules) on and off no matter the context the site is running in. CONFIG SYNC DEVEL Page 21 | Configuration Management: A True Life Story FASTLY SOLR REDIS
Comparison of Config Directories Environment Splits Page 22 | Configuration Management: A True Life Story Feature Splits
Comparison of Settings Files Environment Splits Feature Splits Note: Each config_split is turned OFF by default, enabling splits are cleaner in settings.php Page 23 | Configuration Management: A True Life Story
Configuration Readonly September 1, 2016 Page 24 | Configuration Management: A True Life Story
Configuration Readonly ● ● ● ● Contributed module Prevents administrators from editing active configuration through the User Interface Module can be enabled per environment with Configuration Split Warning: Have a solid continuous integration pipeline and testing procedures in place before enabling in a production environment.

Config Ignore September 1, 2016 Page 26 | Configuration Management: A True Life Story
Config Ignore ● ● ● ● Contributed module Allows for defined config to be ignored by import and export Module can be enabled per environment with Configuration Split Compatibility with Config Readonly: You can use the Config Ignore Readonly module to automatically whitelist configuration forms that are ignored.

Long gone are the days of copying databases, creating a custom module, or creating features to push new functionality to your Drupal Website. Those days and arcane methods are a thing of the past with Drupal 8. Why or how you ask? Read on my friend, read on!
Managing configuration in Drupal 8 has become much easier with the introduction of configuration management. In this talk, we will review “good practices” Oomph and Chromatic have established for configuration management, what tools we use on all of our Drupal 8 projects and how to use them.
We will discuss the following list of modules:
- Configuration Manager
- Configuration Split
- Configuration Read-only mode
- Configuration Ignore
What you can expect to learn from this talk:
- How to export and import configuration in Drupal 8
- How to manage configuration in version control
- How to manage configuration for multiple environments
- How to prevent configuration changes in production
This talk is for all skill levels and aims to make everyone’s life easier through the magic of Drupal Configuration Management. We look forward to sharing our experience with you and answering any questions you may have.
