Installation

Step 1: Download the Bundle

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

composer require macpaw/symfony-health-check-bundle

Applications that don't use Symfony Flex

enable the bundle by adding it to the list of registered bundles in config/bundles.php

// config/bundles.php
<?php

return [
            SymfonyHealthCheckBundle\SymfonyHealthCheckBundle::class => ['all' => true],

        // ...
    ];

Create Symfony Health Check Bundle Config:

Configurating health check - all available you can see here.

# config/packages/symfony_health_check.yaml`
symfony_health_check:
    health_checks:
        - id: symfony_health_check.doctrine_orm_check
    ping_checks:
        - id: symfony_health_check.status_up_check

To perform redis check you need use provide its dsn in the config:

symfony_health_check:
    health_checks:
        ...
        - id: symfony_health_check.redis_check

    redis_dsn: 'redis://localhost:6379'

Change response code:

default response code is 200.
determine your custom response code in case of some check fails (Response code must be a valid HTTP status code)

symfony_health_check:
    health_checks:
        - id: symfony_health_check.doctrine_orm_check
    ping_checks:
        - id: symfony_health_check.status_up_check
    ping_error_response_code: 500
    health_error_response_code: 404

Create Symfony Health Check Bundle Routing Config:

config/routes/symfony_health_check.yaml

health_check:
    resource: '@SymfonyHealthCheckBundle/Resources/config/routes.xml'

Step 3: Configuration

Security Optional:

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

# config/packages/security.yaml
    firewalls:
        healthcheck:
            pattern: ^/health
            security: false
        ping:
            pattern: ^/ping
            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 SymfonyHealthCheckBundle\Dto\Response;

class CustomCheck implements CheckInterface
{
    public function check(): Response
    {
        return new Response('status', true, 'up');
    }
}

Then we add our custom health check to collection

symfony_health_check:
    health_checks:
        - id: symfony_health_check.doctrine_orm_check
        - id: custom_health_check // custom service check id

How Change Route:

You can change the default behavior with a light configuration, remember to modify the routes.

# config/routes/symfony_health_check.yaml
health:
    path: /your/custom/url
    methods: GET
    controller: SymfonyHealthCheckBundle\Controller\HealthController::check
    
ping:
    path: /your/custom/url
    methods: GET
    controller: SymfonyHealthCheckBundle\Controller\PingController::check

How To Use Healthcheck In Docker

HEALTHCHECK --start-period=15s --interval=5s --timeout=3s --retries=3 CMD curl -sS {{your host}}/health || exit 1
