How to set a proxy in official Elasticsearch PHP client?

Question

I know you can do it using the Elastica client like so:

$client = new \Elastica\Client(array(
    'host' => 'my host',
    'port' => '9200',
    'proxy' => 'my proxy'
));

but I'd like to use the official client if possible. I've set up a connection according to the documentation here .

$hosts = [
    [
    'host' => 'my host',
    'port' => '9200',
    'scheme' => 'http',
    'user' => 'my user',
    'pass' => 'my pass'
    ]
];
$client = Elasticsearch\ClientBuilder::create()
   ->setHosts($hosts)
   ->build();

However, there's nothing in the documentation on how to set a proxy. Is it possible?

BTW, I've seen this question , however it's outdated and doesn't work with the current version.

Answer 1

There may be a cleaner syntax, but setting cURL parameters should work:

$client = Elasticsearch\ClientBuilder::create()
   ->setHosts($hosts)
    ->setConnectionParams([
        'client' => [
            'curl' => [
                CURLOPT_PROXY => $proxy
            ]
        ]
    ])
   ->build();
