| <p>In the <code>compose</code> 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.).</p> |
| |
| <p>If the usage is not document in a specific directory the default usage is the following:</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">cd compose/ozone |
| docker-compose up -d</code></pre></div> |
| <p>The data of the container is ephemeral and deleted together with the docker volumes.</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 down</code></pre></div> |
| <h2 id="useful-docker-ozone-commands">Useful Docker & Ozone Commands</h2> |
| |
| <p>If you make any modifications to ozone, the simplest way to test it is to run freon and unit tests.</p> |
| |
| <p>Here are the instructions to run freon in a docker-based cluster.</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</code></pre></div> |
| |
| <p>This will open a bash shell on the data node container. |
| Now we can execute freon for load generation.</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">ozone freon randomkeys --numOfVolumes<span style="color:#f92672">=</span><span style="color:#ae81ff">10</span> --numOfBuckets <span style="color:#ae81ff">10</span> --numOfKeys <span style="color:#ae81ff">10</span></code></pre></div> |
| |
| <p>Here is a set of helpful commands for working with docker for ozone. |
| To check the status of the components:</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 ps</code></pre></div> |
| |
| <p>To get logs from a specific node/service:</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 logs scm</code></pre></div> |
| |
| <p>As the WebUI ports are forwarded to the external machine, you can check the web UI:</p> |
| |
| <ul> |
| <li>For the Storage Container Manager: <a href="http://localhost:9876">http://localhost:9876</a></li> |
| <li>For the Ozone Manager: <a href="http://localhost:9874">http://localhost:9874</a></li> |
| <li>For the Datanode: check the port with <code>docker ps</code> (as there could be multiple data nodes, ports are mapped to the ephemeral port range)</li> |
| </ul> |
| |
| <p>You can start multiple data nodes with:</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 scale datanode<span style="color:#f92672">=</span><span style="color:#ae81ff">3</span></code></pre></div> |
| |
| <p>You can test the commands from the <a href="../shell.html">Ozone CLI</a> after opening a new bash shell in one of the containers:</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</code></pre></div> |
