| Runing with HDFS |
| </h2> |
| <p class="card-text">Ozone is designed to work with HDFS. So it is easy to deploy ozone in an existing HDFS cluster. |
| The container manager part of Ozone can run inside DataNodes as a pluggable module or as a standalone component. This document describe how can it be started as a HDFS datanode plugin. |
| To activate ozone you should define the service plugin implementation class. |
| Important: It should be added to the hdfs-site.xml as the plugin should be activated as part of the normal HDFS Datanode bootstrap.</p> |

| Ozone Containers |
| </h2> |
| <p class="card-text">Docker heavily is used at the ozone development with three principal use-cases: |
| dev: We use docker to start local pseudo-clusters (docker provides unified environment, but no image creation is required) test: We create docker images from the dev branches to test ozone in kubernetes and other container orchestrator system We provide apache/ozone images for each release to make it easier for evaluation of Ozone. These images are not created for production usage.</p> |

| Docker Cheat Sheet |
| </h2> |
| <p class="card-text">In the compose directory of the ozone distribution there are multiple pseudo-cluster setup which can be used to run Ozone in different way (for example: secure cluster, with tracing enabled, with prometheus etc.). |
| If the usage is not document in a specific directory the default usage is the following: |
| cd compose/ozone docker-compose up -d The data of the container is ephemeral and deleted together with the docker volumes. |
| docker-compose down Useful Docker & Ozone Commands If you make any modifications to ozone, the simplest way to test it is to run freon and unit tests.</p> |
