Spring Boot Application issue with rabbitmq in docker - spring

Question

I am trying to build a event driven microservice with spring cloud stream using rabbitmq. In my case, rabbitmq is running in docker.
Docker commands used to run below container
docker run -d --hostname my-rabbit --name some-rabbit --publish 15672:15672 rabbitmq:3
Then going to bash mode of container I fired below command:
rabbitmq-plugins enable rabbitmq_management
in order to start management-plugin
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b2bc315c44aa rabbitmq:3 "docker-entrypoint..." 7 minutes ago Up 7 minutes 4369/tcp, 5671-5672/tcp, 25672/tcp, 0.0.0.0:15672->15672/tcp some-rabbit
So I can access docker from browser on localhost:15672
But when I start the Spring Boot application it is not making queue and exchange. Please check the stack trace.

Thanks in advance.

Answer 1

You need to use the Docker image for RabbitMQ that has the management plugin (see https://hub.docker.com/_/rabbitmq/), in your case rabbitmq:3-management.

Answer 2

I have been wrestling with using rabbit mq running in docker and I think you will need to make some entries in your spring boot application.properties file to overcome the connection problem.
It looks like your exchange is not being created due to connection refused. You need to overcome that. In the rabbit web admin console you will need to create a user with permissions. Then add some configuration in application.properties :
spring.rabbitmq.port=5672
spring.rabbitmq.username=the_user_name
spring.rabbitmq.password=user_password
Good luck.
