# Get started with Data Prepper

Data Prepper is an independent component, not an OpenSearch plugin, that converts data for use with OpenSearch. It's not bundled with the all-in-one OpenSearch installation packages.

## 1. Install Data Prepper

To use the Docker image, pull it like any other image:

```bash
docker pull opensearchproject/data-prepper:latest
```

## 2. Define a pipeline

Create a Data Prepper pipeline file, `pipelines.yaml`, with the following configuration:

```yml
simple-sample-pipeline:
  workers: 2
  delay: "5000"
  source:
    random:
  sink:
    - stdout:
```

## 3. Start Data Prepper

Run the following command with your pipeline configuration YAML.

```bash
docker run --name data-prepper \
    -v /full/path/to/pipelines.yaml:/usr/share/data-prepper/pipelines.yaml \
    opensearchproject/opensearch-data-prepper:latest
```

This sample pipeline configuration above demonstrates a simple pipeline with a source (`random`) sending data to a sink (`stdout`). For more examples and details on more advanced pipeline configurations, see [Pipelines]({{site.url}}{{site.baseurl}}/observability/data-prepper/pipelines).

After starting Data Prepper, you should see log output and some UUIDs after a few seconds:
