"kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection" 仅在列出主题期间

Question

我发现几个主题相似但上下文不同的问题：我可以连接以创建主题，但我无法列出主题，因为我遇到了下面提到的错误（据我所知，人们遇到了问题用于基本连接，而我仅用于列出主题列表）。

以防万一，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"

我的主机：

Created topic test2.
bash-4.4# kafka-topics.sh --list --zookeeper localhost:2181

未来的读者可能会发现我可以直接从我的 Docker Kafka 容器中列出所有主题而无需登录我的 Docker Zookeper 容器 ()

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 似乎工作正常

--zookeeper localhost:2181 总是会在 kafka 容器内失败，因为它不是运行 zookeeper 服务器

I could list all topics straight from my Docker Kafka Container without logging in my Docker Zookeper Container

没错。理想情况下，您永远不应该进入 Zookeeper 容器。 Latest kafka versions support using --bootstrap-server instead，因此您可以使用来自 kafka 容器的 kafka:9092 或 localhost:9092

"kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection" 仅在列出主题期间

"kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection" ONLY DURING LISTING TOPICS

apache-kafka

docker

docker-compose

apache-zookeeper
