Important recommendation: if you use Kafka v2.2+

kafka-topics.sh --bootstrap-server localhost:9092 --topic first_topic --create --partitions 3 --replication-factor 1

kafka-topics.sh --zookeeper localhost:2181 --topic first_topic --create --partitions 3 --replication-factor 1

WARNING: Due to limitations in metric names, topics with a period ('.') or underscore ('_') could collide. To avoid issues it is best to use either, but not both.
Created topic first_topic.

kafka-topics.sh --bootstrap-server localhost:9092 --list

kafka-topics.sh --zookeeper localhost:2181 --list

__consumer_offsets
first_topic

kafka-topics.sh --bootstrap-server localhost:9092 --describe --topic first_topic

kafka-topics.sh --zookeeper localhost:2181 --describe --topic first_topic

Topic: first_topic	TopicId: fN9mf1UDSmiCdKIDFyMEIQ	PartitionCount: 3	ReplicationFactor: 1	Configs: cleanup.policy=delete
Topic: first_topic	Partition: 0	Leader: 1	Replicas: 1	Isr: 1
Topic: first_topic	Partition: 1	Leader: 1	Replicas: 1	Isr: 1
Topic: first_topic	Partition: 2	Leader: 1	Replicas: 1	Isr: 1

Topic: third_topic	TopicId: 84yqCErzTG27J4wv44dkPQ	PartitionCount: 4	ReplicationFactor: 3	Configs: cleanup.policy=delete
Topic: third_topic	Partition: 0	Leader: 2	Replicas: 2,3,1	Isr: 2,3,1
Topic: third_topic	Partition: 1	Leader: 3	Replicas: 3,1,2	Isr: 3,1,2

Topic: third_topic	Partition: 3	Leader: 2	Replicas: 2,1,3	Isr: 2,1,3

Danger: Increasing Partitions

kafka-topics.sh --bootstrap-server localhost:9092 --alter --topic first_topic --partitions 5

kafka-topics.sh --zookeeper localhost:2181 --alter --topic first_topic --partitions 5
