my kubernetes service not connect to rabbitmq on docker container

Question

I'm developing a simple microservice application using kubernetes. I use skaffold for development and production. And I provide communication between my services with rabbitmq.

When I run my kubernetes services locally (i.e. manually without kubernetes) I can connect to my docker container. But when I run my apps through kubernetes I can't connect to my docker container.

The url I use when I try it manually is: BROKER_URI=amqp://127.0.0.1:15672

As I said above url works manually but not with kubernetes. It would also be illogical for it to work because its url is 127.0.0.1. So I wrote a rabbitmq kubernetes service like below.

The url I use when I try it kubernetes is: amqp:://backend-rabbitmq-srv:5672

// backend-rabbitmq-srv.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: backend-rabbitmq-depl
spec:
  replicas: 1
  selector:
    matchLabels:
      app: backend-rabbitmq
  template:
    metadata:
      labels:
        app: backend-rabbitmq
    spec:
      containers:
        - name: backend-rabbitmq
          image: rabbitmq:3
---
apiVersion: v1
kind: Service
metadata:
  name: backend-rabbitmq-srv
spec:
  type: NodePort
  selector:
    app: backend-rabbitmq
  ports:
    - name: http
      protocol: TCP
      port: 15672
      targetPort: 15672
      nodePort: 31672
    - name: amqp
      protocol: TCP
      port: 5672
      targetPort: 5672
      nodePort: 30672

However, I am still getting an error as below. Where could I be missing?

The error:

[is-chat] OperationalError: connect ECONNREFUSED
