docker - 使用Zookeeper和Kafka在容器之间连接失败

Question

我使用kafka，zookeeper，elasticsearch，kafka的3个节点，zk的3个节点

我在Mac上运行docker-compose.yml，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在容器之间进行通信？

还是我需要一些命令来检查或进行docker网络设置？

感谢您的任何建议!

Answer 1

首先，123.345.567不是四个数字，因此这不是有效的虚假IP

Docker compose使用compose服务名称为您建立了一个DNS网络。您将永远不需要Mac在容器内的外部地址。

对于完整运行的Compose文件，look at Confluent's。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计算机上更快地运行，因为它们都共享一个磁盘)

我还建议不要将随机chroot仅添加到您的任何一个Zookeeper(/kafka_test)
