<p>my Connection String in  Container</p>

<pre><code>"DefaultConnection": "Server=mssql-s; Database=ArcadiaAuthenServiceDB; MultipleActiveResultSets=true;User Id=pbts;Password=pbts"
</code></pre>

<p>I try to Created Service End-point in Kubernetes but no luck.</p>

<p>Thank you.</p>

<p>EDIT
Here The Service.yml File</p>

<pre><code>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 
     –--
</code></pre>

<p>EDIT 
I check that SQL Server is Listen to 1433 as well</p>

<pre><code>PS C:\Windows\system32&gt; netstat -aon | findstr 1433   
TCP   0.0.0.0:1433           0.0.0.0:0              LISTENING       5028   
TCP   [::]:1433              [::]:0                 LISTENING       5028
</code></pre>

<p>Is there anything i can do to solve this problem?</p>

<p>Thank you for all your reply.
Today i found solution. it not about k8s but it about Firewall Setting.
I add Inbound rule to allow port 1433. And That it</p>
