| <p><strong><em>This is an alpha release of Ozone. Please don’t use this release in |
| production.</em></strong> Please check the road map page for features under |
| development.</p> |
| |
| <p>The easiest way to run ozone is to download the release tarball and launch |
| ozone via Docker. Docker will create a small ozone cluster on your machine, |
| including the data nodes and ozone services.</p> |
| |
| <h2 id="running-ozone-via-docker">Running Ozone via Docker</h2> |
| |
| <p><strong>This assumes that you have Docker installed on the machine.</strong></p> |
| |
| <ul> |
| <li><p>Download the Ozone tarball and untar it.</p></li> |
| |
| <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 |
| ozone instance on your machine.</p></li> |
| </ul> |
| |
| <div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-bash" data-lang="bash">cd ozone-0.2.1-SNAPSHOT/compose/ozone/ |
| |
| docker-compose up -d</code></pre></div> |
| |
| <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. The ozone freon 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> |
| |
| <div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-bash" data-lang="bash">docker-compose exec datanode bash |
| ozone freon rk</code></pre></div> |
| |
| <p>You can check out the <strong>OzoneManager UI</strong> at <a href="http://localhost:9874/">http://localhost:9874/</a> to see the |
| activity generated by freon. |
| While you are there, please don’t forget to check out the ozone configuration explorer.</p> |
| |
| <p><strong><em>Congratulations, You have just run your first ozone cluster.</em></strong></p> |
| |
| <p>To shutdown the cluster, please run |
| <div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-bash" data-lang="bash">docker-compose down</code></pre></div></p> |
