# Docker

### Prerequisites <a href="#prerequisites" id="prerequisites"></a>

* At least 1Gb of memory
* Two available Kafka API compatible Clusters

### Configure K2K <a href="#configure-hq" id="configure-hq"></a>

To run K2K, you need to provide a YAML configuration file that defines your replication pipeline. This file tells K2K how to move and transform your data.

First, create your replication pipeline definition in a YAML file. For example, let's say you name it `pipeline.yaml`. This file describes the specifics of your data replication.

### Running K2K <a href="#configure-hq" id="configure-hq"></a>

To run K2K as a Docker container, ensure you have your `pipeline.yaml` file ready. Navigate to the directory containing the `pipeline.yaml` file and execute the following command. This command will mount your configuration file into the container and set up the required environment variables for K2K and OpenTelemetry.
