Question

"Setting Ranch options together with socket options is deprecated" warning was appeared in log.

https://github.com/rabbitmq/rabbitmq-server/issues/2069 has a conversation about it.

I used the following Dockerfile to build my own image.

FROM rabbitmq:3.7.20-management

RUN rabbitmq-plugins enable --offline rabbitmq_mqtt rabbitmq_web_mqtt

EXPOSE 1883 15675

then build

docker build -t demo/rabbitmq:3.7.20-management .

then run

docker run -d --name test demo/rabbitmq:3.7.20-management

and docker logs test show
