能否请您帮助解决此问题。

Answer 1

那些错误：Cluster mssql-cluster does not exist. The server was not found or was not accessible 看起来像是部署和配置问题。

所以请遵循以下准则：

• 在部署期间，您可以使用default configuration/custom configuration 之一，
• Monitor the deployment,
• Retrieve endpoints,
• Verify the cluster status,
• Kubernetes troubleshooting,

希望对您有所帮助。
