Windows下使用Docker Compose运行Kafka的问题

Question

我试图在Windows 10 Pro和Docker桌面上本地运行Kafka（而不是工具箱）。一切似乎都工作得很好，但我无法使用我的应用程序访问Kafka，也没有使用Kafka rest（http://localhost:8082/topics http://127.0.0.1:8082/topics http://192.168.1.103:8082/topics-最后一个是我在主机中的docker ip）

我的docker-compose文件是：

version: '2'

services:

我的主机文件是：

# Copyright (c) 1993-2009 Microsoft Corp.

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.

# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.

带有docker-compose的Kafka设置

和谷歌上的许多其他网站

考虑到Docker所涉及的网络，您需要正确配置Kafka监听器。这篇文章解释了如何:https://rmoff.net/2018/08/02/kafka-listeners-complinated/

您可以在以下位置找到包含主机访问的工作Docker组合:https://github.com/confluentinc/examples/blob/5.3.1-post/cp-all-in-one/docker-compose.yml
