如何在 Docker 容器中配置 rabbitmq.config？

Question

我使用的是官方的 RabbitMQ Docker 镜像 (https://hub.docker.com/_/rabbitmq/)

我尝试在运行后编辑容器内的rabbitmq.config文件

docker exec -it <container-id> /bin/bash

但是，这似乎对容器中运行的rabbitmq服务器没有影响。重启容器显然也没有帮助，因为 Docker 启动了一个全新的实例。

所以我假设为 Docker 容器配置 rabbitmq.config 的唯一方法是在容器开始运行之前设置它，我可以使用镜像支持的环境变量来部分完成。

不幸的是，并非所有配置选项都受环境变量支持。例如，我想在rabbitmq.config 中设置{auth_mechanisms, ['PLAIN', 'AMQPLAIN', 'EXTERNAL']}。

然后我找到了RABBITMQ_CONFIG_FILE 环境变量，它应该允许我指向我想用作我的配置文件的文件。但是，我尝试了以下方法，但没有成功：

docker service create --name rabbitmq --network rabbitnet \
-e RABBITMQ_ERLANG_COOKIE='mycookie' --hostname = "{{Service.Name}}{{.Task.Slot}}" \
--mount type=bind,source=/root/mounted,destination=/root \
-e RABBITMQ_CONFIG_FILE=/root/rabbitmq.config rabbitmq

默认的rabbitmq.config 文件包含：

[ { rabbit, [ { loopback_users, [ ] } ] } ]

是容器启动后的内容

在 Docker 容器中配置 rabbitmq.config 的最佳方式是什么？

Answer 1

配置文件位于/etc/rabbitmq/rabbitmq.config，所以如果你用这样的东西挂载你自己的配置文件（我在这里使用 docker-compose 来设置图像）

volumes:
- ./conf/myrabbit.conf:/etc/rabbitmq/rabbitmq.config

应该这样做

我可以使用以下 bash 脚本运行带有已安装配置的 RabbitMQ：

#RabbitMQ props
env=dev
rabbitmq_name=dev_rabbitmq
rabbitmq_port=5672

#RabbitMQ container
if [ "$(docker ps -aq -f name=${rabbitmq_name})" ]; then
    echo Cleanup the existed ${rabbitmq_name} container
    docker stop ${rabbitmq_name} && docker rm ${rabbitmq_name} 
    echo Create and start new ${rabbitmq_name} container
    docker run --name ${rabbitmq_name} -d -p ${rabbitmq_port}:15672 -v $PWD/rabbitmq/${env}/data:/var/lib/rabbitmq:rw -v $PWD/rabbitmq/${env}/definitions.json:/opt/definitions.json:ro -v $PWD/rabbitmq/${env}/rabbitmq.config:/etc/rabbitmq/rabbitmq.config:ro rabbitmq:3-management
else
    echo Create and start new ${rabbitmq_name} container
    docker run --name ${rabbitmq_name} -d -p ${rabbitmq_port}:15672 -v $PWD/rabbitmq/${env}/data:/var/lib/rabbitmq:rw -v $PWD/rabbitmq/${env}/definitions.json:/opt/definitions.json:ro -v $PWD/rabbitmq/${env}/rabbitmq.config:/etc/rabbitmq/rabbitmq.config:ro rabbitmq:3-management    
fi

我的rabbitmq/dev 目录中还有以下config 文件

definitions.json

{
        "rabbit_version": "3.7.3",
        "users": [{
            "name": "welib",

            "hashing_algorithm": "rabbit_password_hashing_sha256",
            "tags": ""
        }, {

        }],

        }, {

            "vhost": "/",
            "configure": ".*",
            "write": ".*",
            "read": ".*"
        }],

        "queues": [],
        "exchanges": [],

    }

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"}
    ]}
].
