Figure out how to do something like moduleExists() inside settings.php for Redis #29

Closed geerlingguy closed 9 years ago

Currently, because the Redis module isn't installed by default, I have to start things with the following line commented in settings.php:

// $settings['cache']['default'] = 'cache.backend.redis';

Only after Drupal is installed and the Redis module is enabled can I uncomment that line and redeploy settings.php. I tried adding the conditional if (\Drupal::moduleHandler()->moduleExists('redis')) { inside settings.php, but it seems the module_handler isn't yet loaded into the container when settings.php is called, so I can't check for the module's existence. I get the error:
