README

Use AWS Secrets as service container parameters in Symfony.

Important

This bundle has branches for Symfony 5 and 6 and is not activelly maintained. Symfony 8 bundle is available as a separate library: https://github.com/constup-foss/symfony8-aws-secrets-bundle . Future versions of the bundle will be developed and maintained using the new development model implemeneted for Symfony 8.

Thank you for well over 200.000 Packagist downloads!

History and honorable mentions

This bundle is loosely based on and inspired by incompass/aws-secrets-bundle (https://github.com/casechek/aws-secrets-bundle). The Incompass bundle is compatible with Symfony 3 and 4, and it looks like it's not updated/maintained anymore. This package is built to be compatible with Symfony 5 and will, over time, get improvements.

If you are still using Symfony 3 or 4, please use the Incompass bundle instead of this one.

Prerequisites

Install AWS SDK

Since the official recommendation from Symfony is: A bundle must not embed third-party PHP libraries. It should rely on the standard Symfony autoloading instead., the aws/aws-sdk-php Composer package is included in this bundle only as a dev dependency (for testing purposes).

You need to install AWS SDK for PHP in your project yourself:

composer require aws/aws-sdk-php

AWS credentials

In order to connect to any AWS service (for example: AWS Secrets Manager), your application must be authenticated on that AWS service. Since there are several scenarios for this, depending on your environment setup, configuring environments and using credentials is covered here: AWS credentials and authentication

Installation

There are two main versions of AWS Secrets bundle: 1.x and 2.x.

Install version 1.x to use this package with Symfony 5.x (5.3+) and PHP 7.4.

$ composer require constup/aws-secrets-bundle:^1

Install version 2.x to use this package with Symfony 6.x and PHP 8.x.

$ composer require constup/aws-secrets-bundle:^2

Configuration

By default, configuration for this bundle is loaded from config/packages/aws_secrets.yaml file or its environment-specific alternatives (for example: config/packages/test/aws_secrets.yaml). The following configuration properties are available:

aws_secrets:
  client_config:
    region:           # Required if "ignore" is false.
    version: 'latest' # Defaults to "latest".
    endpoint: ~
    credentials: 
        key: ~
        secret: ~
  cache: 'array'      # Can be one of the following: apcu, array, filesystem. Default is array.
  delimiter: ','      # Delimiter to separate key from secret name.
  ignore: false       # Pass through AWS (for local dev environments set to "true").

Usage

Set an env var to an AWS Secret Manager Secret name like so:

AWS_SECRET=secret_name

If you want to grab a key in a JSON secret, you can separate the secret name and key:

AWS_SECRET=secret_name,key

Set a parameter to this environment variable with the aws processor:

parameters:
    my_parameter: '%env(aws:AWS_SECRET)%'

Your secret will now be loaded at runtime!
