错误-无法解析地址：zookeeper：2181-Docker

Question

我在远程计算机上为zookeeper和kafka安装了Confluent Docker Image。我设置以下环境变量属性。

version: '2'
services:
  zookeeper:
    image: confluentinc/cp-zookeeper:latest
    hostname: zookeeper
  ports:
      - "2181:2181"
environment:
  ZOOKEEPER_SERVER_ID: 1
  ZOOKEEPER_CLIENT_PORT: 2181
  ZOOKEEPER_SERVERS: zookeeper:2888:3888

kafka-1:
image: confluentinc/cp-kafka:latest
hostname: kafka
ports:
  - "9092:9092"
environment:
  KAFKA_BROKER_ID: 1
  KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
  KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:9092

当我检查远程计算机中的日志时，出现以下错误。我尝试了在SO和其他一些网站上找到的所有解决方案，但没有成功。错误如下。

错误是

ERROR org.apache.zookeeper.client.StaticHostProvider - Unable to resolve address: zookeeper:2181

非常感谢您的帮助。

如果您为两个容器定义了相同的网络，它们将能够互相看到：

version: '2'
