I am currently building a Drupal 8 application which is running outside Acquia Cloud, and I noticed there are a few 'magic' settings I'm used to working on Acquia Cloud which don't work if you aren't inside an Acquia or Pantheon environment; most notably, the automatic Configuration Split settings choice (for environments like local
, dev
, and prod
) don't work if you're in a custom hosting environment.
You have to basically reset the settings BLT provides, and tell Drupal which config split should be active based on your own logic. In my case, I have a site which only has a local, ci, and prod environment. To override the settings defined in BLT's included config.settings.php
file, I created a config.settings.php
file in my site in the path docroot/sites/settings/config.settings.php
, and I put in the following contents:
<?php
/**
* Settings overrides for configuration management.
*/// Disable all splits which may have been enabled by BLT's configuration.
foreach ($split_envs as $split_env) {
$config["$split_filename_prefix.$split_env"]['status'] = FALSE;
}
$split = 'none';
// Local env.
if ($is_local_env) {
$split = 'local';
}
// CI env.
if ($is_ci_env) {
$split = 'ci';
}
// Prod env.
if (getenv('K8S_ENVIRONMENT') == 'prod') {
$split = 'prod';
}
// Enable the environment split only if it exists.
if ($split != 'none') {
$config["$split_filename_prefix.$split"]['status'] = TRUE;
}
The K8S_ENVIRONMENT
refers to an environment variable I have set up in the production Kubernetes cluster where the BLT Drupal 8 codebase is running. There are a few other little tweaks I've made to make this BLT project build and run inside a Kubernetes cluster, but I'll leave those for another blog post and another day :)
