README

This module provides essential tools for exposing a health check endpoint in your app. It can be used in vanilla php code, but for maximum ease of use, it's recommended to make use of the provided symfony bundle.

Installing and configuring the symfony bundle

• Run:

composer require talentrydev/health-check

• Add the symfony bundle to your kernel's registerBundles method:

return [
    //...
    new \Talentry\HealthCheck\SymfonyBundle\HealthCheckBundle();
]; 

• Configure the bundle by adding the following to your symfony config.yaml file. See below for all available options and their default values (everything is optional).

health_check:
  service_name: API //this is the name of the root service that will appear in the health check endpoint response
  mysql:
    enabled: true //set to false to disable the mysql health checker
    host: localhost
    port: 3306
    user: root
    password: root
    database: mysql
  redis:
    enabled: true //set to false to disable the redis health checker
    host: localhost
    port: 6379

• Add the following you your routing config:

healthcheck:
    resource: "@HealthCheckBundle/Resources/config/routing.yml"

Using the health check endpoint

Make a GET HTTP request to /healthcheck

This will perform a health check of the application itself, but not of the dependent services. To also perform a health check on these services, add them to the URL like so:

<base_url>/healthcheck?mysql=1&redis=1

or specify dependencies=1 to run a health check on all dependencies:

<base_url>/healthcheck?dependencies=1

Extending the bundle

To create your own health checker, simply implement Talentry\HealthCheck\HealthChecker\HealthChecker interface. The name you specify in the return of the getServiceName is the name you will pass to the health check endpoint.
