README
Provides structure for healthcheck endpoints in accordance with IETF's healthcheck draft RFC
About
Package provides endpoints which conform to draft 06 version of IETF's healthcheck RFC.
Integrations
We are shipping following integrations, but it's very easy to implement your own by reusing CallableHealthChecker:
- HTTP request
- Doctrine Connection
Installation
Install this package as a dependency using Composer.
composer require eqs/health-check-provider
Usage
This library provides PSR-15 HTTP Server Request Handler, which guarantees compatibility with wide range of PHP frameworks. In case your framework does not natively support it, you can find a PSR bridge which supports it.
Example controller for Symfony framework
For this example, on top of standard symfony packages, you also need php-http/discovery
and symfony/psr-http-message-bridge
packages.
