| <p>Download the Ozone binary tarball and untar it.</p> |

| <li> |
| <p>Go to the directory where the docker compose files exist and tell |
| <code>docker-compose</code> to start Ozone in the background. This will start a small |

| <p>To verify that ozone is working as expected, let us log into a data node and |
| run <em>freon</em>, the load generator for Ozone. The <code>exec datanode bash</code> command |
| will open a bash shell on the datanode.</p> |
| <p>The <code>ozone freon</code> command is executed within the datanode container. You can quit freon via CTRL-C any time. The |
| <code>rk</code> profile instructs freon to generate random keys.</p> |

| <p>You can check out the <strong>OzoneManager UI</strong> at http://localhost:9874/ to see the |
| activity generated by freon. |
| While you are there, please don’t forget to check out the ozone configuration explorer.</p> |
