Kafka docker配置失败，返回错误:没有为侦听器PLAINTEXT定义安全协议

Question

这就是我的docker文件的样子，

version: "3.9"
services:
zookeeper:
image: 'bitnami/zookeeper:latest'
ports:
- '2181:2181'
environment:
- ALLOW_ANONYMOUS_LOGIN=yes
kafka:
image: 'bitnami/kafka:latest'
ports:
- '9092:9092'
- '9093:9093'
environment:
- KAFKA_BROKER_ID=1
- KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CLIENT:PLAINTEXT,EXTERNAL:PLAINTEXT
- KAFKA_CFG_LISTENERS=PLAINTEXT://:9092,EXTERNAL://:9093
- KAFKA_CFG_ADVERTISED_LISTENERS=PLAINTEXT://127.0.0.1:9092,EXTERNAL://localhost:9093
- KAFKA_CFG_ZOOKEEPER_CONNECT=zookeeper:2181
- ALLOW_PLAINTEXT_LISTENER=yes
- KAFKA_CFG_INTER_BROKER_LISTENER_NAME=CLIENT
- KAFKA_ZOOKEEPER_PROTOCOL=PLAINTEXT
depends_on:
- zookeeper

当我运行下面的docker文件是错误的，我得到

我已经按照下面码头工人帮助中提到的说明进行了操作

https://hub.docker.com/r/bitnami/kafka/

请告诉我该怎么修？

Answer 1

您的错误很可能来自KAFKA_CFG_INTER_BROKER_LISTENER_NAME=CLIENT或KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CLIENT:PLAINTEXT

您尚未将CLIENT定义为侦听器。

此外，您发布的两个侦听器都是localhost。使用IP地址不会改变这一点。。。bitnami Kafka容器自述中有如何分离内部和外部侦听器地址的说明

Answer 2

我按照本页的说明进行了操作，它按预期工作，
