Question

我在Kubernetes（minikube）中有一个dotnet核心Pod，需要访问本地SQL Server（测试服务器）。它在容器中工作，但当我将其放入吊舱中时。它无法在我的计算机上运行sql服务器

但是我可以从Pod ping我的SQL Server

这是日志中的错误

 An error occurred using the connection to database
> 'ArcadiaAuthenServiceDB' on server '192.168.2.68'.
> System.Data.SqlClient.SqlException (0x80131904): A network-related or
> instance-specific error occurred while establishing a connection to

ping

root@authenservice-dpm-57455f59cf-7rqvz:/app# ping 192.168.2.68

我在容器中的连接字符串

"DefaultConnection": "Server=mssql-s; Database=ArcadiaAuthenServiceDB; MultipleActiveResultSets=true;User Id=pbts;Password=pbts"

我尝试在Kubernetes中创建服务端点，但是没有运气。

谢谢。

编辑这是Service.yml文件

apiVersion: v1  
     kind: Service  
     metadata: 
         name: mssql-s 
         namespace: default  spec: 
         ports: 
         - port: 1433 
     ---  
     apiVersion: v1  
     kind: Endpoints  
     metadata: 
         name: mssql-s 
         namespace: default  subsets: 
        - addresses: 
        - ip: 192.168.2.68 
         ports: 
         - port: 1433 
     –--

编辑我检查SQL Server是否也监听1433

PS C:\Windows\system32> netstat -aon | findstr 1433   
TCP   0.0.0.0:1433           0.0.0.0:0              LISTENING       5028   
TCP   [::]:1433              [::]:0                 LISTENING       5028

有什么我可以解决的问题吗？

感谢您的所有答复。今天我找到了解决方案。它与k8无关，而与防火墙设置有关。我添加了入站规则以允许端口1433。并且

Kubernetes中的dotnet核心Pod连接到本地SQL Server
