solved.

because i didn't add user information in zookeeper. add this code.

  zookeeper-add-kafka-users:
    image: confluentinc/cp-kafka:6.0.1
    container_name: "zookeeper-add-kafka-users"
    depends_on:
      - zookeeper1
      - zookeeper2
      - zookeeper3
    command: "bash -c 'echo Waiting for Zookeeper to be ready... && 
                          cub zk-ready zookeeper1:2181 120 && 
                          cub zk-ready zookeeper2:2182 120 && 
                          cub zk-ready zookeeper3:2183 120 && 
                          kafka-configs --zookeeper zookeeper1:2181 --alter --add-config 'SCRAM-SHA-512=[iterations=4096,password=password]' --entity-type users --entity-name admin && 
                          kafka-configs --zookeeper zookeeper1:2181 --alter --add-config 'SCRAM-SHA-512=[iterations=4096,password=password]' --entity-type users --entity-name client '"
    environment:
      KAFKA_BROKER_ID: ignored
      KAFKA_ZOOKEEPER_CONNECT: ignored
      KAFKA_OPTS: -Djava.security.auth.login.config=/etc/kafka/secrets/sasl/kafka_server_jaas.conf
    volumes:
      - /home/mysend/dev/docker/kafka/sasl:/etc/kafka/secrets/sasl

kafka SASL_PLAIN SCRAM
if don't use docker can use command

bin/kafka-configs --zookeeper localhost:2181 --alter --add-config 'SCRAM-SHA-256=[password=admin-secret],SCRAM-SHA-512=[password=admin-secret]' --entity-type users --entity-name admin
