Question

背景

我们在docker-compose设置中具有RabbitMQ管理docker映像，我们正在尝试与一些已添加的用户，虚拟主机和交换一起启动Rabbit。但是，启动程序崩溃了，我们不知道为什么。

我们尝试了什么

我们有一个名为“ rabbitmq”的文件夹，其中包含以下文件（这是我们的配置文件夹）：

definitions.json

{
    "rabbit_version": "3.8.2",
    "users": [
     {
      "name": "user1",
      "password_hash": "user1",
      "hashing_algorithm": "rabbit_password_hashing_sha256",
      "tags": ""
     }
    ],
    "vhosts": [
     {
      "name": "\/vhost1"
     }
    ],
    "permissions": [
     {
      "user": "user1",
      "vhost": "\/vhost1",
      "configure": ".*",
      "write": ".*",
      "read": ".*"
     }
    ],
    "parameters": [],
    "policies": [],
    "queues": [],
    "exchanges": [
        {
            "name": "Pizza",
            "vhost": "\/vhost1",
            "type": "fanout"
        }
    ],
    "bindings": []
   }

rabbitmq.conf

loopback_users.guest = false
listeners.tcp.default = 5672
management.load_definitions = "/etc/rabbitmq/definitions.json"

要使用此设置，我们有以下docker-compose文件：

version: '3'
services:
  rabbit:
    image: rabbitmq:3.8.2-management
    ports:
      - "8080:15672"
      - "5672:5672"
    volumes: 
      - ${PWD}/rabbitmq:/etc/rabbitmq

我们知道RabbitMQ找到了该文件夹并尝试加载rabbitmq.conf文件。实际上，这就是我们问题的起点。

问题

当我们尝试启动安装程序时，RabbitMQ无法启动并显示以下消息：

BOOT FAILED
rabbit_1  | ===========
rabbit_1  |
rabbit_1  | Config file generation failed:
rabbit_1  | 10:46:43.479 [error] You've tried to set management.load_definitions, but there is no setting with that name.
rabbit_1  | 10:46:43.479 [error]   Did you mean one of these?

rabbit_1  | {"init terminating in do_boot",generate_config_file}
rabbit_1  |
rabbit_1  | Crash dump is being written to: /var/log/rabbitmq/erl_crash.dump...done

这令人困惑。我们正在使用rabbitmq:3.8.2-management图片，因此默认情况下应启用管理插件。

我们在做什么错了？

问题

我们收到此错误的原因是在docker-compose文件中：

version: '3'
services:
  rabbit:
    image: rabbitmq:3.8.2-management
    ports:
      - "8080:15672"
      - "5672:5672"
    volumes: 
      - ${PWD}/rabbitmq:/etc/rabbitmq

具体来说，卷部分：${PWD}/rabbitmq:/etc/rabbitmq

这里的问题是，此命令用我们的文件夹彻底粉碎了原始的rabbitmq文件夹。这意味着原始/ etc / rabbitmq文件夹中的所有其他文件都会丢失。

这不是我们的目的，我们的目的是将文件添加到原始文件夹中，如果文件已经存在，请替换它们。

解决方案

以下docker-compose可解决此问题：

version: '3'
services:
  rabbit:
    image: rabbitmq:3.8.2-management
    ports:
      - "8080:15672"
      - "5672:5672"
    volumes: 
      - ${PWD}/rabbitmq/rabbitmq.conf:/etc/rabbitmq/rabbitmq.conf
      - ${PWD}/rabbitmq/definitions.json:/etc/rabbitmq/definitions.json

在这里，我们仅推送和替换所需文件，而保留原始文件夹中的其余内容。

这意味着/etc/rabbitmq内的plugins文件夹不会被删除，并且插件（例如管理版）将被加载，我们将能够通过rabbitmq.conf文件对其进行配置

rabbitmq rabbit.conf文件中的未知变量“ management.load_definitions”
