<p>When provision a new cluster, you need to initialize that cluster's <a href="/docs/en/2.6.4/concepts-architecture-overview#metadata-store">metadata</a>. When initializing cluster metadata, you need to specify all of the following:</p>
<ul>
<li>The name of the cluster</li>
<li>The local ZooKeeper connection string for the cluster</li>
<li>The configuration store connection string for the entire instance</li>
<li>The web service URL for the cluster</li>
<li>A broker service URL enabling interaction with the <a href="/docs/en/2.6.4/reference-terminology#broker">brokers</a> in the cluster</li>
</ul>
<p>You must initialize cluster metadata <em>before</em> starting up any <a href="/docs/en/2.6.4/admin-api-brokers">brokers</a> that will belong to the cluster.</p>

<p>Unlike most other admin functions in Pulsar, cluster metadata initialization cannot be performed via the admin REST API
or the admin Java client, as metadata initialization involves communicating with ZooKeeper directly.
Instead, you can use the <a href="/docs/en/2.6.4/reference-cli-tools#pulsar"><code>pulsar</code></a> CLI tool, in particular
the <a href="/docs/en/2.6.4/reference-cli-tools#pulsar-initialize-cluster-metadata"><code>initialize-cluster-metadata</code></a> command.</p>
</blockquote>
<p>Here's an example cluster metadata initialization command:</p>
<pre><code class="hljs css language-shell">bin/pulsar initialize-cluster-metadata \
--cluster us-west \
--zookeeper zk1.us-west.example.com:2181 \
--configuration-store zk1.us-west.example.com:2184 \

--broker-service-url pulsar://pulsar.us-west.example.com:6650/ \
--broker-service-url-tls pulsar+ssl://pulsar.us-west.example.com:6651/
</code></pre>
<p>You'll need to use <code>--*-tls</code> flags only if you're using <a href="/docs/en/2.6.4/security-tls-authentication">TLS authentication</a> in your instance.</p>
