Hi @starryrbs
We have not test Bridge to Kubernetes on the sample app you've shared.
From the error message you've shared, the SQL server might not allow connection from your local dev box. Can you try to connect to SQL server from your dev box?

[starryrbs]

I confirm that the SQL server is available on my development machine.
I use the following command:

kubectl port-forward deployment/sqldata -n eshopondapr 7888:1433 --address 0.0.0.0

On my development machine, it can be connected.

Using the connection string "Server=sqldata;Database=Microsoft.eShopOnDapr.Services.CatalogDb;User Id=sa;Password=Pass@word" in my application fails to connect.

In the database-api sample project, I was able to connect to MongoDB normally.

I have tried many times, but it still doesn't work. Can you help me find out what the problem is?

[rakeshvanga]

@starryrbs Thanks for the details. It seems that you are trying to connect to sql server using port-forward. Can you try to connect directly without using port-forward?

Also, I will try out the sample application you've shared to understand the issue you are facing.

[starryrbs]

I tried to use sqldata on my machine to connect, but could not connect.

I looked at the run log.

There are no changes to the hosts file.
However, using database-api updates the hosts file.

This is a DAPR app. I tried the dapr supported version and reported the same error.

This is the log of the pod that failed to start on the kube cluster.

In addition, thank you very much for your reply, @rakeshvanga.
