Installation

This library can be installed with composer:

composer require sensiolabs/consul-php-sdk

Usage

The simple way to use this SDK, is to instantiate the service factory:

$sf = new SensioLabs\Consul\ServiceFactory();

Then, a service could be retrieve from this factory:

$kv = $sf->get(\SensioLabs\Consul\Services\KVInterface::class);

Then, a service expose few methods mapped from the consul API:

$kv->put('test/foo/bar', 'bazinga');
$kv->get('test/foo/bar', ['raw' => true]);
$kv->delete('test/foo/bar');

All services methods follow the same convention:

$response = $service->method($mandatoryArgument, $someOptions);

All API mandatory arguments are placed as first;
All API optional arguments are directly mapped from $someOptions;
All methods return a raw http client response.

So if you want to acquire an exclusive lock:

// Start a session
$sessionId = $session->create()->json()['ID'];

// Lock a key / value with the current session
$lockAcquired = $kv->put('tests/session/a-lock', 'a value', ['acquire' => $sessionId])->json();

if (false === $lockAcquired) {
    $session->destroy($sessionId);

    echo "The lock is already acquire by another node.\n";
    exit(1);
}

echo "Do you jobs here....";
sleep(5);
echo "End\n";

$kv->delete('tests/session/a-lock');
$session->destroy($sessionId);
