无法从另一个Pod K8s连接RabbitMQ Pod

问题描述

我目前正在尝试部署一个应用程序来连接Rabbitmq。

应用程序和Rabbitmq位于同一群集节点上的不同容器中。

我无法通过服务名或群集IP连接到RabbitMQ。

您对这个问题有任何想法吗？

对应用程序的认知

None of the specified endpoints were reachable

这是Rabbitmq_deployment.yaml

 apiVersion: apps/v1
 kind: Deployment
 Metadata:
   name: rabbitmq
   namespace: test
 spec:
   selector:
     matchLabels:
       run: rabbitmq
   replicas: 1
   template:
     Metadata:
       labels:
         run: rabbitmq
     spec:
       containers:
       - name: rabbitmq
         image: rabbitmq_delay_v3.7
         imagePullPolicy: IfNotPresent

 apiVersion: v1
 kind: Service
 Metadata:

   namespace: test
   labels:
     run: rabbitmq

   - name: rabbit-web
     protocol: TCP
     port: 15672
     targetPort: 15672
     nodePort: 30000
   - name: rabbit-svc
     protocol: TCP
     port: 5672
     targetPort: 5672
   selector:
     run: rabbitmq

这是app_deployment.yaml

    apiVersion: apps/v1
    kind: Deployment
    Metadata:
      name: app_test
      namespace: test
    spec:
      selector:

        spec:
          containers:
          - name: app1
            image: my_app_image
            imagePullPolicy: IfNotPresent
            env:
              - name: "ASPNETCORE_ENVIRONMENT"
                value: "Staging"
    ---
    apiVersion: v1
    kind: Service

      ports:
      - name: app_test_port
        protocol: TCP
        port: 80
        targetPort: 80
        nodePort: 30203
      selector:
        run: app_test

这是在应用程序上连接Rabbitmq的配置

"QueueConfig": {
        "HostName": "rabbitmq-svc","UserName": "guest","Pwd": "guest","VirtualHost": "/","Port": 5672,}

这里是kubectl -n test describe avc rabbitmq-svc

的输出

  Name:                     rabbitmq-svc
  Namespace:                test
  Labels:                   run=rabbitmq
  Annotations:              Selector:  run=rabbitmq

这里是kubectl get pods -n kube-system

的输出
