ElasticsearchBundle

Integration of the Elasticsearch official PHP client within a Symfony Project.

Features

This bundle creates one or more Elasticsearch client services from settings defined in the application configuration.

Usage

Installation

You must first add the bundle to your composer.json:

    "require": {
        "m6web/elasticsearch-bundle": "dev-master"
    }

Then register the bundle in your AppKernel class:

<?php
    public function registerBundles()
    {
        $bundles = array(
            // ...
            new M6Web\Bundle\ElasticsearchBundle\M6WebElasticsearchBundle(),
        );
        // ...
    }

Configuration

In your config.yml, you can configure one or more Elasticsearch clients:

m6web_elasticsearch:
    default_client: my_client
    clients:
        my_client:
            hosts:
                - 'localhost:9200'
                - 'http://other_host:9201'
        my_other_client:
            hosts:
                - 'other_server:9200'

From this configuration, the bundle will create two services :

• m6web_elasticsearch.client.my_client that will connect to two Elasticsearch instances: localhost on port 9200 and other_host on port 9201
• m6web_elasticsearch.client.my_other_client that will connect to one Elasticsearch instances: other_server on port 9200

It will also create m6web_elasticsearch.client.default which is an alias for m6web_elasticsearch.client.my_client

Additional configuration

Each client can have additional configuration parameters that will be used to instantiate the \Elasticsearch\Client. Ex:

m6web_elasticsearch:
    clients:
        my_client:
            hosts:
                - 'https://username:password@localhost:9200'
            headers:
                'Accept-Encoding': ['gzip']
            retries: 2
            logger: monolog.logger.custom
            connectionPoolClass: '\Elasticsearch\ConnectionPool\StaticConnectionPool'
            selectorClass: '\Elasticsearch\ConnectionPool\Selectors\RandomSelector'
            connectionParams:
                client:
                    timeout: 3
                    connect_timeout: 1

Events

The bundle dispatches \M6Web\Bundle\ElasticsearchBundle\EventDispatcher\ElasticsearchEvent events containing various information about the Elasticsearch requests.

Events are fired with the name m6web.elasticsearch.

Tests

You can launch the unit tests using:
