docker - 使用 zookeeper 和 kafka 在容器之间连接失败

问题描述

我用的是kafka，zookeeper，elasticsearch，kafka的3个节点，zk的3个节点

我docker-compose.yml在我的 Mac 上运行， 123.345.567是以下命令的输出：

ifconfig | grep 'inet 192'| awk '{ print $2}'

docker-compose.yml 是

version: '2'

我想知道这些容器是否不需要 ip:123.345.567。

也许他们需要一些inner ip容器之间的通信？

或者我需要一些命令来检查或进行 docker 网络设置？

谢谢你的任何建议！

解决方案

首先，123.345.567不是四个数字，所以这不是一个有效的假 IP

Docker compose 使用 compose 服务名称为您设置 DNS 网络。您永远不需要在容器中使用 Mac 的外部地址。

如需完整的 Compose 文件，请查看 Confluent 的. 从一个 Zookeeper 和 Broker 开始，然后开始工作（Kafka 不会在具有多个容器的单台机器上运行得更快，因为它们都共享一个磁盘）

我还建议不要只向你的一个 Zookeepers 添加随机 chroot ( /kafka_test)
