“kafka.zookeeper.ZooKeeperClientTimeoutException：等待连接超时”仅在列出主题期间

我发现了一些主题相似但上下文不同的问题：我可以连接以创建主题，但无法列出主题，因为我收到了下面提到的错误（据我所知，人们在我时面临基本连接问题）我只是为了列出主题列表）。

如果重要的话，这是我的docker-compose.yml:

version: "3"
services:
    zookeeper:
        image: wurstmeister/zookeeper

    kafka:
        image: wurstmeister/kafka
        ports:
            - "9092:9092"
        environment:
            KAFKA_ADVERTISED_HOST_NAME: "localhost"
            KAFKA_ZOOKEEPER_CONNECT: "zookeeper:2181"

我的控制台：

bash-4.4# kafka-topics.sh --create --zookeeper zookeeper:2181 --replication-factor 1 --partitions 1 --topic test2
Created topic test2.
bash-4.4# kafka-topics.sh --list --zookeeper localhost:2181

未来的读者可能会发现，如何直接从 Docker Kafka 容器列出所有主题，而无需登录 Docker Zookeper 容器（https://stackoverflow.com/a/56595227/4148175)

C:\Users\>docker exec -it test1_kafka_1 bash

bash-4.4# kafka-topics.sh --list --bootstrap-server localhost:9092
__consumer_offsets
test2
test3
test_topic
bash-4.4# 

--zookeeper zookeeper:2181似乎效果很好

--zookeeper localhost:2181在kafka容器内总是会失败，因为它没有运行zookeeper服务器

我可以直接从 Docker Kafka 容器列出所有主题，而无需登录 Docker Zookeper 容器

这是正确的。理想情况下，您永远不应该进入 Zookeeper 容器。最新的kafka版本支持使用--bootstrap-server instead，所以你可以使用kafka:9092 or localhost:9092来自卡夫卡容器
