如何连接到主机的docker容器Laravel?

Question

我的服务使用RabbitMQ。为了使用它，我安装了这个包https://github.com/vyuldashev/laravel-queue-rabbitmq。要使用这个包，需要配置配置文件

'hosts' => [
[
'host' => env('RABBITMQ_HOST', '127.0.0.1'),
'port' => env('RABBITMQ_PORT', 5672),
'user' => env('RABBITMQ_USER', 'guest'),
'password' => env('RABBITMQ_PASSWORD', 'guest'),
'vhost' => env('RABBITMQ_VHOST', '/'),
],
],

你可以看到，ip被指定为127.0.0.1，但是我的docker容器有一个动态ip，所以它每次都更新，我必须手动修复配置

这是我的docker-compose文件

我如何告诉rabbitmq容器连接到应用程序容器的外部ip ?

Answer 1

对不起，我混淆了Redis和RabbitMQ。所以这里可能是一个更好的匹配答案:

你可以从Docker容器连接到主机上的服务，即使IP发生了变化-在这篇文章中有一个脚本和一个很好的答案。

一些摘录:

如果你在Mac或Windows上，你可以设置

RABBITMQ_HOST=host.docker.internal

一般更容易，我会考虑一个单独的容器运行RabbitMQ，然后使用rabbitmq作为主机名连接。

services:
# ... other services
rabbitmq:
image: rabbitmq:alpine
environment:
RABBITMQ_DEFAULT_USER: "defaultuser"
RABBITMQ_DEFAULT_PASS: "defaultpass"
ports:
- 5672:5672
