confluentinc/cp-kafka docker log4j warnings

Question

docker pull confluentinc/cp-kafka

docker run --rm -d --name kafka-server -p 9092:9092 -e ALLOW_PLAINTEXT_LISTENER=yes -e KAFKA_ZOOKEEPER_CONNECT=192.168.1.164:2181 -e KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR=1 -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://localhost:9092 confluentinc/cp-kafka

然而，它将立即关闭并给出日志：

log4j:WARN No appenders could be found for logger (io.confluent.admin.utils.cli.ZookeeperReadyCommand).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

如何解决这个log4j错误？(通过终端(

注：ALLOW_PLAINTEXT_LISTENER=yes用于bitnami/kafka图像，而非汇流
