Esb Health Check Symfony Bundle

Installation

Step 1: Download the Bundle

Open a command console, enter your project directory and execute:

Applications that use Symfony Flex

$ composer require esb/health-check-symfony

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

<?php

// config/bundles.php

return [
    // ...
    Esb\HealthCheckSymfony\HealthCheckSymfonyBundle::class => ['all' => true],    
];

Create Config files:

config/packages/health_check_symfony.yaml

health_check_symfony:
    checks:
        - id: Esb\HealthCheckSymfony\Checks\DoctrineCheck
        - id: Esb\HealthCheckSymfony\Checks\RedisCheck

    rabbitmq_queues: # optional
      - name: 'queue_name'

    kafka: # optional
        group:
        broker_list:
        sasl_username:
        sasl_password:
        security_protocol:
        sasl_mechanism:
        env: test
        topics:
            - name: topic_name # env is concatenated, example: test.topic_name

---

config/routes/health_check_symfony.yaml

health_check:
    path: /healthcheck
    methods: GET
    controller: Esb\HealthCheckSymfony\Controller\HealthCheckController::index

Step 3: Configuration

Security Optional:

config/packages/security.yaml

If you are using symfony/security and your health check is to be used anonymously, add a new firewall to the configuration

    firewalls:
        healthcheck:
            pattern: ^/healthcheck
            security: false

Step 4: Additional settings

Add Custom Check:

It is possible to add your custom health check:

<?php
declare(strict_types=1);
namespace YourProject\Check;

use Esb\HealthCheck\HealthCheck;
use Esb\HealthCheck\Status;

class CustomCheck extends HealthCheck
{
    public function name(): string
    {
        return 'custom_check_name';
    }

    public function handle(): Status
    {
        return $this->okay();
    }
}

Then add custom health check to collection

health_check_symfony:
    checks:
        - id: Esb\HealthCheckSymfony\Checks\DoctrineCheck
        - id: Esb\HealthCheckSymfony\Checks\RedisCheck
        - id: YourProject\Check\CustomCheck
