As mentioned in [Getting started with Data Prepper]({{site.url}}{{site.baseurl}}/data-prepper/getting-started/), you'll need to configure Data Prepper with a pipeline using a `pipelines.yaml` file.
1. To install Data Prepper's Docker image, see Installing Data Prepper in [Getting Started]({{site.url}}{{site.baseurl}}/data-prepper/getting-started#1-installing-data-prepper).
2. Run the Docker image installed in Step 1 by supplying your `logstash.conf` configuration.
```
docker run --name data-prepper -p 4900:4900 -v ${PWD}/logstash.conf:/usr/share/data-prepper/pipelines.conf opensearchproject/data-prepper:latest pipelines.conf
```
The `logstash.conf` file is converted to `logstash.yaml` by mapping the plugins and attributes in the Logstash configuration to the corresponding plugins and attributes in Data Prepper.
You can find the converted `logstash.yaml` file in the same directory where you stored `logstash.conf`.
The following output in your terminal indicates that Data Prepper is running correctly:
```
INFO org.opensearch.dataprepper.pipeline.ProcessWorker - log-pipeline Worker: No records received from buffer
