I'm new in Apache Kafwa world and start using Apache Kafka Client. So I start one docker container with Apache Kafka and Zookeeper, but I can't understand what of API key and URL I need to provide to this class https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/admin/AdminClient.java . I read the java doc, And I know that this client is responsible for creating topics and etc. But I don't know how to configure it.
