<p>For Windows, enter something like the following docker command:</p>
<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> docker run -it \</span>
  -p 6650:6650 \
  -p 8080:8080 \
  -v "$PWD/data:/pulsar/data".ToLower() \
  apachepulsar/pulsar:2.3.1 \
  bin/pulsar standalone
</code></pre>
<p>A few things to note about this command:</p>
<ul>
<li><code>$PWD/data</code> : The docker host directory in Windows operating system must be lowercase.<code>$PWD/data</code> provides you with the specified directory, for example: <code>E:/data</code>.</li>
<li><code>-v $PWD/data:/pulsar/data</code>: This makes the process inside the container to store the
data and metadata in the filesystem outside the container, in order not to start &quot;fresh&quot; every time the container is restarted.</li>
</ul>
<p>If you start Pulsar successfully, you will see <code>INFO</code>-level log messages like this:</p>

<p>When you start a local standalone cluster, a <code>public/default</code> namespace is created automatically. The namespace is used for development purposes. All Pulsar topics are managed within namespaces. For more information, see <a href="/docs/en/2.3.1/concepts-messaging#topics">Topics</a>.</p>

<p>Pulsar offers client libraries for <a href="/docs/en/2.3.1/client-libraries-java">Java</a>, <a href="/docs/en/2.3.1/client-libraries-go">Go</a>, <a href="/docs/en/2.3.1/client-libraries-python">Python</a>
and <a href="/docs/en/2.3.1/client-libraries-cpp">C++</a>. If you're running a local standalone cluster, you can
use one of these root URLs to interact with your cluster:</p>
<ul>
<li><code>pulsar://localhost:6650</code></li>
<li><code>http://localhost:8080</code></li>
</ul>
<p>The following example will guide you get started with Pulsar quickly by using the <a href="/docs/en/2.3.1/client-libraries-python">Python</a>
client API.</p>
<p>Install the Pulsar Python client library directly from <a href="https://pypi.org/project/pulsar-client/">PyPI</a>:</p>
<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> pip install pulsar-client</span>
</code></pre>
<p>Create a consumer and subscribe to the topic:</p>
<pre><code class="hljs css language-python"><span class="hljs-keyword">import</span> pulsar

client = pulsar.Client(<span class="hljs-string">'pulsar://localhost:6650'</span>)
consumer = client.subscribe(<span class="hljs-string">'my-topic'</span>,
                            subscription_name=<span class="hljs-string">'my-sub'</span>)

<span class="hljs-keyword">while</span> <span class="hljs-literal">True</span>:
    msg = consumer.receive()
    print(<span class="hljs-string">"Received message: '%s'"</span> % msg.data())
    consumer.acknowledge(msg)

client.close()
</code></pre>
<p>Now start a producer to send some test messages:</p>
<pre><code class="hljs css language-python"><span class="hljs-keyword">import</span> pulsar

client = pulsar.Client(<span class="hljs-string">'pulsar://localhost:6650'</span>)
producer = client.create_producer(<span class="hljs-string">'my-topic'</span>)

<span class="hljs-keyword">for</span> i <span class="hljs-keyword">in</span> range(<span class="hljs-number">10</span>):
    producer.send((<span class="hljs-string">'hello-pulsar-%d'</span> % i).encode(<span class="hljs-string">'utf-8'</span>))

client.close()
</code></pre>

<p>In Pulsar, you can use REST, Java, or command-line tools to control every aspect of the system.
For details on APIs, refer to <a href="/docs/en/2.3.1/admin-api-overview">Admin API Overview</a>.</p>
<p>In the simplest example, you can use curl to probe the stats for a particular topic:</p>
<pre><code class="hljs css language-shell"><span class="hljs-meta">$</span><span class="bash"> curl http://localhost:8080/admin/v2/persistent/public/default/my-topic/stats | python -m json.tool</span>
</code></pre>
<p>The output is something like this:</p>
<pre><code class="hljs css language-json">{
