--- layout: default title: Get Started parent: Data Prepper nav_order: 1 --- # 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, `my-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/my-pipelines.yaml:/usr/share/data-prepper/pipelines/my-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}}/clients/data-prepper/pipelines). After starting Data Prepper, you should see log output and some UUIDs after a few seconds: ``` 2021-09-30T20:19:44,147 [main] INFO org.opensearch.dataprepper.pipeline.server.DataPrepperServer - Data Prepper server running at :4900 2021-09-30T20:19:44,681 [random-source-pool-0] INFO org.opensearch.dataprepper.plugins.source.RandomStringSource - Writing to buffer 2021-09-30T20:19:45,183 [random-source-pool-0] INFO org.opensearch.dataprepper.plugins.source.RandomStringSource - Writing to buffer 2021-09-30T20:19:45,687 [random-source-pool-0] INFO org.opensearch.dataprepper.plugins.source.RandomStringSource - Writing to buffer 2021-09-30T20:19:46,191 [random-source-pool-0] INFO org.opensearch.dataprepper.plugins.source.RandomStringSource - Writing to buffer 2021-09-30T20:19:46,694 [random-source-pool-0] INFO org.opensearch.dataprepper.plugins.source.RandomStringSource - Writing to buffer 2021-09-30T20:19:47,200 [random-source-pool-0] INFO org.opensearch.dataprepper.plugins.source.RandomStringSource - Writing to buffer 2021-09-30T20:19:49,181 [simple-test-pipeline-processor-worker-1-thread-1] INFO org.opensearch.dataprepper.pipeline.ProcessWorker - simple-test-pipeline Worker: Processing 6 records from buffer {"message":"1043a78e-1312-4341-8c1e-227e34a1fbf3"} {"message":"b1529b81-1ee1-4cdb-b5d7-11586e570ae6"} {"message":"56d83593-4c95-4bc4-9c0b-e061d9b23192"} {"message":"254153df-4534-4f5e-bb31-98b984f2ac29"} {"message":"ad1430e6-8486-4d84-a2ef-de30315dea07"} {"message":"81c5e621-79aa-4850-9bf1-68642d70c1ee"} ```
