Question

从docker-compose我得到了这个yml：

version: '2'
services:
  zookeeper:
    container_name: zookeeper
    image: confluentinc/cp-zookeeper:3.1.1
    ports:
      - "2080:2080"
    environment:
      - ZOOKEEPER_CLIENT_PORT=2080
      - ZOOKEEPER_TICK_TIME=2000

  kafka:
    container_name: kafka
    image: confluentinc/cp-kafka:3.1.1
    ports:
      - "9092:9092"
    environment:
      - KAFKA_CREATE_TOPICS=Topic1:1
      - KAFKA_ZOOKEEPER_CONNECT=192.168.99.100:2080
      - KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.99.100:9092
    depends_on:
      - zookeeper

  schema-registry:
    container_name: schema-registry
    image: confluentinc/cp-schema-registry:3.1.1
    ports:
      - "8081:8081"
    environment:
      - SCHEMA_REGISTRY_KAFKASTORE_CONNECTION_URL=192.168.99.100:2080
      - SCHEMA_REGISTRY_HOST_NAME=localhost
    depends_on:
      - zookeeper
      - kafka

当我站起来时，控制台输出结束于：

schema-registry | Error while running kafka-ready.
schema-registry | org.apache.kafka.common.errors.TimeoutException: Timed out waiting for Kafka to create /brokers/ids in Zookeeper. timeout (ms) = 40000
schema-registry exited with code 1

似乎kafka从未连接过Zookeper或类似的东西，有谁知道为什么会这样？

要更改

SCHEMA_REGISTRY_KAFKASTORE_CONNECTION_URL=192.168.99.100:2080

进入

SCHEMA_REGISTRY_KAFKASTORE_CONNECTION_URL=zookeeper:2080

帮助？

此外，KAFKA_ZOOKEEPER_CONNECT=192.168.99.100:2080还应提及zookeeper，而不是IP地址。或者，您如何确定该IP地址？

KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.99.100:9092提到了您可能也无法保证的IP地址。对于后者，可以将该IP地址更改为kafka。

在让Kafka和Zookeeper在Docker中工作（通过Docker Compose）方面，我也遇到了挑战。最后，https://github.com/confluentinc/cp-docker-images/blob/5.0.0-post/examples/kafka-single-node/docker-compose.yml为我工作。您可以将其用作灵感来源。

无法将Kafka连接到Zookeeper
