<p>Under the hood, both the <code>pulsar-admin</code> CLI tool and the Java client both use the REST API. If you’d like to implement your own admin interface client, you should use the REST API as well. Full documentation can be found here.</p>

<p>In this document, examples from each of the three available interfaces will be shown.</p>

<p>Each of Pulsar's three admin interfaces---the <a href="/docs/en/2.5.2/reference-pulsar-admin"><code>pulsar-admin</code></a> CLI tool, the <a href="/api/admin/2.5.0-SNAPSHOT">Java admin API</a>, and the <a href="https://pulsar.apache.org/admin-rest-api#/">REST</a>

<p>If you have <a href="/docs/en/2.5.2/security-overview#authentication-providers">authentication</a> enabled, you will need to provide an auth configuration to use the <a href="/docs/en/2.5.2/reference-pulsar-admin"><code>pulsar-admin</code></a> tool. By default, the configuration for the <code>pulsar-admin</code> tool is found in the <a href="/docs/en/2.5.2/reference-configuration#client"><code>conf/client.conf</code></a> file. Here are the available parameters:</p>

<p>To use the Java admin API, instantiate a <a href="https://pulsar.apache.org/api/admin/2.5.0-SNAPSHOT/org/apache/pulsar/client/admin/PulsarAdmin">PulsarAdmin</a>
 object, specifying a URL for a Pulsar <a href="/docs/en/2.5.2/reference-terminology#broker">broker</a> and a <a href="https://pulsar.apache.org/api/admin/2.5.0-SNAPSHOT/org/apache/pulsar/client/admin/PulsarAdminBuilder">PulsarAdminBuilder</a>
. Here's a minimal example using <code>localhost</code>:</p>
<pre><code class="hljs css language-java">String url = <span class="hljs-string">"http://localhost:8080"</span>;
<span class="hljs-comment">// Pass auth-plugin class fully-qualified name if Pulsar-security enabled</span>
String authPluginClassName = <span class="hljs-string">"com.org.MyAuthPluginClass"</span>;
<span class="hljs-comment">// Pass auth-param if auth-plugin class requires it</span>
String authParams = <span class="hljs-string">"param1=value1"</span>;
<span class="hljs-keyword">boolean</span> useTls = <span class="hljs-keyword">false</span>;
<span class="hljs-keyword">boolean</span> tlsAllowInsecureConnection = <span class="hljs-keyword">false</span>;
String tlsTrustCertsFilePath = <span class="hljs-keyword">null</span>;
PulsarAdmin admin = PulsarAdmin.builder()
.authentication(authPluginClassName,authParams)
.serviceHttpUrl(url)
.tlsTrustCertsFilePath(tlsTrustCertsFilePath)
.allowTlsInsecureConnection(tlsAllowInsecureConnection)
.build();
</code></pre>
<p>If you have multiple brokers to use, you can use multi-host like Pulsar service. For example,</p>
<pre><code class="hljs css language-java">String url = <span class="hljs-string">"http://localhost:8080,localhost:8081,localhost:8082"</span>;
<span class="hljs-comment">// Pass auth-plugin class fully-qualified name if Pulsar-security enabled</span>
String authPluginClassName = <span class="hljs-string">"com.org.MyAuthPluginClass"</span>;
<span class="hljs-comment">// Pass auth-param if auth-plugin class requires it</span>
String authParams = <span class="hljs-string">"param1=value1"</span>;
<span class="hljs-keyword">boolean</span> useTls = <span class="hljs-keyword">false</span>;
<span class="hljs-keyword">boolean</span> tlsAllowInsecureConnection = <span class="hljs-keyword">false</span>;
String tlsTrustCertsFilePath = <span class="hljs-keyword">null</span>;
PulsarAdmin admin = PulsarAdmin.builder()
.authentication(authPluginClassName,authParams)
.serviceHttpUrl(url)
.tlsTrustCertsFilePath(tlsTrustCertsFilePath)
.allowTlsInsecureConnection(tlsAllowInsecureConnection)
.build();
