Admin setup

Each of the three admin interfaces (the pulsar-admin CLI tool, the REST API, and the Java admin API requires some special setup if you have enabled authentication in your Pulsar instance.

pulsar-admin

If you have enabled authentication, you need to provide an auth configuration to use the pulsar-admin tool. By default, the configuration for the pulsar-admin tool is in the conf/client.conf file. The following are the available parameters:

Name	Description	Default
webServiceUrl	The web URL for the cluster.	http://localhost:8080/
brokerServiceUrl	The Pulsar protocol URL for the cluster.	pulsar://localhost:6650/
authPlugin	The authentication plugin.
authParams	The authentication parameters for the cluster, as a comma-separated string.
useTls	Whether or not TLS authentication will be enforced in the cluster.	false
tlsAllowInsecureConnection	Accept untrusted TLS certificate from client.	false
tlsTrustCertsFilePath	Path for the trusted TLS certificate file.

REST API

You can find details for the REST API exposed by Pulsar brokers in REST API doc.

Java

To use the Java admin API, instantiate a PulsarAdmin object, and specify a URL for a Pulsar broker and a PulsarAdminBuilder. The following is a minimal example using localhost.

String url = "http://localhost:8080";
// Pass auth-plugin class fully-qualified name if Pulsar-security enabled
String authPluginClassName = "com.org.MyAuthPluginClass";
// Pass auth-param if auth-plugin class requires it
String authParams = "param1=value1";
boolean tlsAllowInsecureConnection = false;
String tlsTrustCertsFilePath = null;
PulsarAdmin admin = PulsarAdmin.builder()
    .authentication(authPluginClassName,authParams)
    .serviceHttpUrl(url)
    .tlsTrustCertsFilePath(tlsTrustCertsFilePath)
    .allowTlsInsecureConnection(tlsAllowInsecureConnection)
    .build();

If you use multiple brokers, you can use multi-host like Pulsar service. For example,

String url = "http://localhost:8080,localhost:8081,localhost:8082";
// Below are the same to the line 2 - line 13 in the code snippet above
// Pass auth-plugin class fully-qualified name if Pulsar-security enabled
String authPluginClassName = "com.org.MyAuthPluginClass";
// Pass auth-param if auth-plugin class requires it
String authParams = "param1=value1";
boolean tlsAllowInsecureConnection = false;
String tlsTrustCertsFilePath = null;
PulsarAdmin admin = PulsarAdmin.builder()
    .authentication(authPluginClassName,authParams)
    .serviceHttpUrl(url)
    .tlsTrustCertsFilePath(tlsTrustCertsFilePath)
    .allowTlsInsecureConnection(tlsAllowInsecureConnection)
    .build();
