ECONNREFUSED：無法連接到集群內默認埠上的RabbitMQpod

2021-10-19 12:16:40 軟體設計

我的本地集群中有一個運行 RabbitMQ 的 pod。我已將其配置為：

apiVersion: v1
kind: Service
metadata:
  name: service-rabbitmq
spec:
  selector:
    app: service-rabbitmq
  ports:
    - name: rabbitmq-amqp
      port: 5672
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: statefulset-rabbitmq
spec:
  selector:
    matchLabels:
      app: statefulset-rabbitmq
  serviceName: service-rabbitmq
  template:
    metadata:
      labels:
        app: statefulset-rabbitmq
    spec:
      containers:
        - name: rabbitmq
          image: rabbitmq:latest
          volumeMounts:
            - name: rabbitmq-data-volume
              mountPath: /var/lib/rabbitmq/mnesia
          resources:
            requests:
              cpu: 250m
              memory: 256Mi
            limits:
              cpu: 750m
              memory: 512Mi
          # livenessProbe:
          #   exec:
          #     command:
          #       - 'rabbitmq-diagnostics'
          #       - 'ping'
          #       - '--quiet'
      volumes:
        - name: rabbitmq-data-volume
          persistentVolumeClaim:
            claimName: rabbitmq-pvc

我已經習慣amqp://service-rabbitmq:5672連接到它。當我同時部署 RabbitMQ 和應用程式 pod 時，出現以下錯誤：

$ kubectl get pods

RabbitMQ 服務器似乎已成功啟動 - 我沒有看到任何錯誤：

所以看起來吊艙沒有問題，到目前為止一切看起來都很完美。那為什么我不能從我的應用程式連接到它？

uj5u.com熱心網友回復：

所以問題是Service選擇器與Pod的標簽不匹配。正確的清單是：

apiVersion: v1
kind: Service
metadata:
  name: service-rabbitmq
spec:
  selector:
-   app: service-rabbitmq
    app: statefulset-rabbitmq
