oracle - 如何从Kubernetes连接到外部Oracle数据库？

Question

我正在使用kubernetes设置新服务器以运行Spring Boot微服务。我如何将Spring Boot App连接到外部Oracle数据库？ (数据库ip为170.27.10.10:1521)

Kube Master的IP:170.16.163.10
Kube Node的IP:170.16.163.11
Kube Node可以连接到服务器数据库。

我通过命令创建部署:

kubectl run db-deployment --image 170.16.163.30:5000/mcrdb:0.0.4 --replicas=2 --port=8083
kubectl expose deployment db-deployment --type=LoadBalancer --port=8083 --target-port=8083

并创建服务:

kind: "Service"
apiVersion: "v1"
metadata:
  name: "dbdev"
spec:
  ports:
    -
      name: "oracle-db"
      protocol: "TCP"
      port: 1521
      targetPort: 1521 
      nodePort: 0


kind: Endpoints
apiVersion: v1
metadata:
 name: dbdev
subsets:
 - addresses:
     - ip: 170.27.10.10
   ports:
     - port: 1521

并在application.properties中配置db

spring.datasource.url=jdbc:oracle:thin:@170.27.10.10:1521/vservice
spring.datasource.username=dev_user
spring.datasource.password=dev_pass

微服务无法启动并错误连接到oracle db。

您可以尝试以下更改吗

kind: Service
apiVersion: v1
metadata:
  name: dbdev
spec:
  ports:
    -
      name: oracle-db
      protocol: TCP
      port: 1521
      targetPort: 1521 


kind: Endpoints
apiVersion: v1
metadata:
 name: dbdev
subsets:
 - addresses:
     - ip: 170.27.10.10
   ports:
     - port: 1521

application.properties
------------------------
spring.datasource.url=jdbc:oracle:thin:@dbdev:1521/vservice
spring.datasource.username=dev_user
spring.datasource.password=dev_pass
