Config

Component for fetching, merging, and validating configuration from various sources.

Introduction

Whenever you have various environments for multiple purposes: production, staging, test, local and more the need arises to keep the configuration of those consistent across possibly different platforms like local environments and some external storage like AWS Simple Systems Manager and not to fail during critical deploy.

This component allows you to keep it tight in one source with a predefined yaml solution.

Installation

composer require piotrkreft/config

Usage

Configuration

example configuration

ℹ️ Variables declared within envs scope take the precedence over global ones.

ℹ️ Global variables can be disabled in specific env with the disable flag.

CLI

Validation of entries:

vendor/bin/pk-config -c config.yaml validate dev

Displaying of entries:

vendor/bin/pk-config -c config.yaml display dev

PHP

use PK\Config\ConfigFactory;

$config = ConfigFactory::create(realpath('config.yaml'));

$config->validate('dev');

$config->fetch('dev');

Symfony Bundle

It's possible to use the component as a Symfony Bundle. Just make sure you have symfony/http-kernel installed and add PK\Config\PKConfigBundle to your application Kernel.

If used as such commands will receive pk:config: and can be used like:

bin/console pk:config:validate dev

Adapters

To be able to use a different configuration sources adapters are needed. By default, package provides:

• aws_ssm (multiple)(PK\Config\StorageAdapter\{AwsSsm, AwsSsmByPath}) - for AWS Simple Systems Manager parameters
• local_env (PK\Config\StorageAdapter\LocalEnv) - for local environment variables

and each of those is available to be instantiated via component configuration.

If needed a new adapter can be easily created. Just remember to interface it with PK\Config\StorageAdapterInterface and to instantiate it.

ℹ️ Order of the adapters in each environment is also a priority. If the first adapter provides value, the following will be ignored.

ℹ️ If adapter has multiple option assigned it can be configured with multiple different instances. If so each can be referenced in env.adapters like {adapter}.{name} (i.e. aws_ssm.default)
