Configuration

Introduction

phd uses an environment variables based configuration, see also Dev/prod parity for more information about this topic.

Environment settings

The following list displays configuration locations from highest to lowest priority, files are located in the application root folder.

  1. docker-compose.override.yml (needs container restart)
  2. docker-compose.yml (needs container restart)
  3. Dockerfile (needs rebuilding)
  4. .env (can be change at runtime during developemt)

defaults for .env, see .env-dist

ENV variable are immutable by default, so if a value is set in a Dockerfile, you can not overwrite it in your .env file, but in docker-compose.yml.

Only values in .env can be changed while the containers are running. If you change environment variables in docker-compose.yml you need to restart your containers.

Application settings

You find the config files for an application in src/config, those can also be changed at runtime:

❗ An important difference between application and environment configuration is that ENV variables are immutable by default, but values in PHP arrays can be overwritten.

Usage

Basic settings

Initial configuration adjustments should be made for the following values

  • APP_NAME
  • APP_TITLE
  • APP_LANGUAGES

.env-dist can be adjusted and committed to reflect basic application settings, but we strongly recommend not to add secrets like passwords or tokens to the repository.

During local development it is also recommended to enable debug settings in .env.

YII_ENV=dev
YII_DEBUG=1

‼️ Make sure you do not have these settings enabled in production deployments.

You can also enable additional migrations during local development.

APP_MIGRATION_LOOKUP=@app/migrations/data

It is recommended to keep structural and data migrations separated.

Database migrations

Lookup paths for migrations can be defined in application configuration, for details see dmstr/yii2-migrate-command.

'params'      => [
    'yii.migrations' => [
        '@yii/rbac/migrations',
        '@dektrium/user/migrations',
        '@vendor/lajax/yii2-translate-manager/migrations',
        '@bedezign/yii2/audit/migrations'
    ]
]

Asset bundles

By default phd runs with the default bootstrap asset bundle from Yii. To enable asset customization, edit src/assets/AppAsset.php and uncomment 'less/app.less',.

There are three files included by default:

  • app.less main LESS file for application
  • bootstrap.less includes for bootstrap LESS files
  • variables.less bootstrap settings

Initial adjustment to the style settings of the application should be made in variables.less

When developing assets you can set APP_ASSET_FORCE_PUBLISH=1 in your local .env file, this improves detection of changes for included files. Note: This feature is only available in the AppAsset bundle for the application.

For bundling assets for production usage, see tutorial about asset compression.
