rabbit create queue

[wubin19896817]

hello，how I can create the queue if the rabbitmq don't have?

[jonapich]

Use the management plugin (please google around) to create them dynamically, or you can also provide a definition file if you have a static setup.

All of this information should be very easy to find on the rabbitmq official site. I suggest you start with the "hello world" tutorial.

For any further questions about how to use the software, you should rather use sites like stackoverflow.com

Hello @jonapich , I searched for definition file, didn't find.

Do you have an example or a link about it?

Thanks you,

[jonapich]

I would guess that's the same file that can be exported through the management plugin (look for export/import buttons at the bottom). I might be wrong though, I never had to use it.

Ha got it:

1- Create definitions.json (you can export it from management web UI) or:

{
  "rabbit_version": "3.6.5",
  "users": [
    {
      "name": "guest",
      "password_hash": "o2MJjT8UKSRM7eoLDMWvm4LxqaFvDxd2wLg1KQQQ2jXfG5UE",
      "hashing_algorithm": "rabbit_password_hashing_sha256",
      "tags": "administrator"
    }
  ],
  "vhosts": [
    {
      "name": "/"
    }
  ],
  "permissions": [
    {
      "user": "guest",
      "vhost": "/",
      "configure": ".*",
      "write": ".*",
      "read": ".*"
    }
  ],
  "parameters": [],
  "policies": [],
  "queues": [
    {
      "name": "events-v1",
      "vhost": "/",
      "durable": true,
      "auto_delete": false,
      "arguments": {
        "x-ha-policy": "all"
      }
    }
  ],
  "exchanges": [],
  "bindings": [
    {
      "source": "amq.direct",
      "vhost": "/",
      "destination": "events-v1",
      "destination_type": "queue",
      "routing_key": "logstash",
      "arguments": {}
    },
    {
      "source": "amq.direct",
      "vhost": "/",
      "destination": "events-v1",
      "destination_type": "queue",
      "routing_key": "v1",
      "arguments": {}
    }
  ]
}

2- Set filepath in rabbitmq.config:

[
    {rabbit, [
        {loopback_users, []},
        {vm_memory_high_watermark, 0.7},
        {vm_memory_high_watermark_paging_ratio, 0.8},
        {log_levels, [{channel, warning}, {connection, warning}, {federation, warning}, {mirroring, info}]},
        {heartbeat, 10}
    ]},
    {rabbitmq_management, [
        {load_definitions, "/opt/definitions.json"}
    ]}
].

3- Mount files as volume:

  rabbitmq:
    image: rabbitmq:3.6.5-management
    volumes:
      - rabbitmq:/var/lib/rabbitmq:rw
      - ./images/datahub_rabbitmq/definitions.json:/opt/definitions.json:ro
      - ./images/datahub_rabbitmq/rabbitmq.config:/etc/rabbitmq/rabbitmq.config:ro

When I try to $docker-compose up I see that:
…
rabbitmq_1 | /usr/local/bin/docker-entrypoint.sh: line 262: /etc/rabbitmq/rabbitmq.config: Read-only file system
…
All config is the same. What I do wrong?

@sylogex that usually means you've also supplied environment variables to the rabbitmq image which are requesting that we update the configuration (which is bind-mounted as read-only, so that can't work)

However, as of #112, the images will auto-detect and load /etc/rabbitmq/definitons.json, so you should be able to simply place your definitons.json file there and have the management image load them appropriately with no additional configuration or changes. 👍
