如何在RabbitMQ不活动时添加RabbitMQ用户

Question

我在服务器的Docker容器中运行RabbitMQ服务和Celery。Worker是通过RabbitMQ连接到服务器的芹菜实例。

我这样设置并运行RabbitMQ：

sudo service rabbitmq-server start
rabbitmqctl add_user bunny password
rabbitmqctl add_vhost bunny_host
rabbitmqctl set_permissions -p bunny_host bunny ".*" ".*" ".*"

这有一个问题：如果一个工作者试图在正在启动的服务和正在创建并被授予权限的bunny用户之间进行连接，那么该工作者的芹菜实例将终止。

我试着把它添加到Dockerfile中，让我的服务器在"实时"启动之前添加用户：

RUN sudo service rabbitmq-server start && 
    rabbitmqctl add_user bunny password && 
    rabbitmqctl add_vhost bunny_host && 
    rabbitmqctl set_permissions -p bunny_host bunny ".*" ".*" ".*" && 
    sudo service rabbitmq-server stop

但是当我在容器中重新启动rabbitmqserver服务时，用户bunny并不存在。

(如果我尝试在服务未运行时使用rabbitmqctl添加用户，它会出错。(

任何帮助都将不胜感激。

在构建期间不能运行rabbitmqctl。相反，您可以通过使用引导文件来实现同样的目的。你需要像下面的片段一样更新你的文件

Dockerfile

FROM rabbitmq:3.6.11-management-alpine
ADD rabbitmq.config /etc/rabbitmq/
ADD definitions.json /etc/rabbitmq/
RUN chmod 666 /etc/rabbitmq/*

rabbitmq.config

[
  {
    rabbit,
  [
    { loopback_users, [] }
  ]
},
  {
    rabbitmq_management,
  [
    { load_definitions, "/etc/rabbitmq/definitions.json" }
  ]
}
].

definitions.json

{
  "rabbit_version": "3.6.14",
  "users": [
    {
      "name": "user",
      "password_hash": "0xZBvBD2JOGWrVO84nZ62EJuQIRehcILEiPVFB9mD4zhFcAo",
      "hashing_algorithm": "rabbit_password_hashing_sha256",
      "tags": "administrator"
    }
  ],
  "vhosts": [
    {
      "name": "/"
    }
  ],
  "permissions": [
    {
      "user": "community",
      "vhost": "/",
      "configure": ".*",
      "write": ".*",
      "read": ".*"
    }
  ],
  "parameters": [],
  "global_parameters": [
    {
      "name": "cluster_name",
      "value": "rabbit@rabbitmq"
    }
  ],

  "queues": [],
  "exchanges": [],
  "bindings": []
}
