我正在使用官方 RabbitMQ Docker 映像（https://hub.docker.com/_/rabbitmq/）

我尝试rabbitmq.config在运行后编辑容器内的文件

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。

因此，我假设rabbitmq.config为 Docker 容器配置的唯一方法是在容器开始运行之前对其进行设置，我能够部分使用镜像支持的环境变量来完成。

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

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rabbitmq.config文件包含：

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

是容器启动后的内容

rabbitmq.config在 Docker 容器中进行配置的最佳方式是什么？

配置文件存在，/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

我的目录中也有以下config文件rabbitmq/dev
