Spring 如何连接kubernetes的无头Mongo服务

我已经使用了上述yaml。Mongo Db正在使用kubectl exec命令进行良好检查。下面是用于部署spring引导应用程序的yaml

apiVersion: v1
kind: Service
metadata:
 name: mongo
 labels:
  name: mongo
spec:
 ports:
  - port: 27017
    targetPort: 27017
 clusterIP: None
 selector:
  name: mongo
---
apiVersion: apps/v1beta1
kind: StatefulSet
metadata:
 name: mongo
spec:
 serviceName: "mongo"
 replicas: 1
 template:
  metadata:
   labels:
    name: mongo
#    environment: test
  spec:
   terminationGracePeriodSeconds: 10
   volumes:
    - name: mongo-pv-storage
      persistentVolumeClaim:
       claimName: mongo-pv-claim
   containers:
    - name: mongo
      image: mongo:4.0.12-xenial
      command:
       - mongod
       - "--bind_ip"
       - 0.0.0.0
       - "--smallfiles"
       - "--noprealloc"
      ports:
       - containerPort: 27017
         name: mongo
      volumeMounts:
       - name: mongo-pv-storage
         mountPath: /data/db

我得到的例外是

apiVersion: apps/v1
kind: Deployment
metadata:
  name: imageprocessor-app-backend
  labels:
    app: imageprocessor-app-backend
spec:
  # modify replicas according to your case
  selector:
    matchLabels:
      tier: imageprocessor-app-backend
  template:
    metadata:
      labels:
        tier: imageprocessor-app-backend
    spec:
      containers:
      - name: imageprocessor-app-backend
        image: imageprocessor-app-backend:v1
        ports:
        - containerPort: 8099
        env:
        - name: spring.data.mongodb.host
          value: mongo-0.mongo
        - name: spring.data.mongodb.port
          value: "27017"
        - name: spring.data.mongodb.database
          value: testdb

apiVersion: v1
kind: Service
metadata:
  name: imageprocessor-app-backend

    nodePort: 31471
  selector:
    tier: imageprocessor-app-backend

如何使用我的应用程序连接headless mongo服务。我尝试使用-name:spring.data.mongodb.host

value:mongo-0.mongo//和value:mongo

您需要使用服务的名称作为主机名。在您的示例中，它是

mongo

。我使用上面的YAML部署了mongo，我可以从同一名称空间中的另一个pod成功连接到它

---

如果您在另一个命名空间中运行

imageprocessor app backend

，则必须将运行

mongo

的命名空间添加到主机名：

mongo.

，例如

mongo.mongo

，您需要使用服务名称作为主机名。在您的示例中，它是

mongo

。我使用上面的YAML部署了mongo，我可以从同一名称空间中的另一个pod成功连接到它

---

如果您在另一个命名空间中运行

imageprocessor应用程序后端

，然后运行

mongo

，则必须将运行

mongo

的命名空间添加到主机名：

mongo.

，例如

mongo.mongo

，您好，请检查我上传的图像（）。名称空间相同，但仍不起作用我有未注释的clusterIP:None。请检查新yaml的服务正确的主机名应该是

mongo

或

mongo.default

。我想我的集群出现了一些问题。在我重新设置集群后，它工作正常，yaml没有任何变化。主机名是mongo-0.mongo。@JibinNajeeb，我无法使用默认名称空间的mongo-0.mongo创建复制集。您在群集中遇到了什么问题？您好，请检查我上载的图像（）。名称空间相同，但仍不起作用我有未注释的clusterIP:None。请检查新yaml的服务正确的主机名应该是
