I actually can't recall why I did it this way, but here's how I implemented this package for our readinessProbe
A health route:
// health routes
Route::get('/health', 'HealthCheckController@index');
A custom HealthCheckController:
<?php
namespace App\Http\Controllers;
use PragmaRX\Health\Http\Controllers\Health;
class HealthCheckController extends Controller {
public function index() {
$services = array_map('strtolower', config('health.resources.enabled'));
foreach($services as $service){
$serviceHealth = app('pragmarx.health')->checkResource($service)->isHealthy();
if (!$serviceHealth) {
return "Service: $service is not healthy";
}
}
return 'Healthy!';
}
}
a PHP file to call call this health check by-passing laravel (this is where I'm not sure why I did it this way)
<?php
// Start output buffering (Capture STDOUT)
ob_start();
// Check that artisan ran through start.sh
//if (!file_exists('/ready')) { exit(1); }
// Check that php-fpm is running as well
$output = shell_exec('ps aux | grep [p]hp-fpm');
if (empty($output)){
echo "Can't find php-fpm, exiting with error";
exit(1);
}
$host = getenv('PLACEHOLDER_API_URL_NO_PROTOCOL');
if (empty($host)){
$host = 'local.api.REMOVED.com';
}
$_SERVER['REQUEST_URI'] = '/v1.0/health';
$_SERVER['HTTP_ACCEPT'] = '*/*';
$_SERVER['HTTP_USER_AGENT'] = 'curl/7.47.0';
$_SERVER['HTTP_CONNECTION'] = 'close';
$_SERVER['HTTP_HOST'] = $host;
// Start output buffering (Capture STDOUT)
ob_start();
require_once 'server.php';
$content = ob_get_contents();
if (strpos($content, 'Healthy!') !== false) {
// Success
exit(0);
} else {
// Failure
echo "Content is not Healthy! val: $content";
exit(1);
}
ob_end_clean();
and lastly the readinessProbe config:
readinessProbe:
exec:
command:
- php
- /var/www/health_check.php
There MIGHT be a reason I decided to do the HTTP request in a "health_check" php file rather than doing it from the readinessProbe, but I couldn't explain why anymore. Sorry, that was a long time ago
Is this package support kubernetes pods health check? If support can I have small example?
