# Configuration

Configuring Kafka connection and topics in Ecotone

## Installation

```php
composer require ecotone/kafka
```

Implementation is based on [rdkafka](https://github.com/arnaud-lb/php-rdkafka).

## Configuration

In order to use **Kafka Support** we need to add **KafkaBrokerConfiguration** to our **Dependency Container.**

{% tabs %}
{% tab title="Symfony" %}

```php
# config/services.yaml
# You need to have Kafka instance running on your localhost, or change DSN
    Ecotone\Kafka\Configuration\KafkaBrokerConfiguration:
        class: Ecotone\Kafka\Configuration\KafkaBrokerConfiguration
        arguments:
            $bootstrapServers:
                - localhost:9094
```

{% endtab %}

{% tab title="Laravel" %}

```php
# Register Kafka Service in Provider

use Ecotone\Kafka\Configuration\KafkaBrokerConfiguration;

public function register()
{
     $this->app->singleton(KafkaBrokerConfiguration::class, function () {
         return new KafkaBrokerConfiguration(['localhost:9094']);
     });
}
```

{% endtab %}

{% tab title="Lite" %}

```php
use Ecotone\Kafka\Configuration\KafkaBrokerConfiguration;

$application = EcotoneLiteApplication::boostrap(
    [
        KafkaBrokerConfiguration::class => new KafkaBrokerConfiguration(['localhost:9094'])
    ]
);
```

{% endtab %}
{% endtabs %}

{% hint style="info" %}
We register our **KafkaBrokerConfiguration** under the class name **Ecotone\Kafka\Configuration\KafkaBrokerConfiguration**. This will help Ecotone resolve it automatically, without any additional configuration.
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ecotone.tech/modules/kafka-support/configuration.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
