Note

The article is being updated.

Below are examples of the code for authentication using a service account file in different YDB SDKs.

Go

Java

package main
import (
    "context"
    "os"
    "github.com/ydb-platform/ydb-go-sdk/v3"
    yc "github.com/ydb-platform/ydb-go-yc"
)
func main() {
    ctx, cancel := context.WithCancel(context.Background())
    defer cancel()
    db, err := ydb.Open(
        ctx,
        os.Getenv("YDB_CONNECTION_STRING"),
        yc.WithServiceAccountKeyFileCredentials(
            os.Getenv("YDB_SERVICE_ACCOUNT_KEY_FILE_CREDENTIALS"),
        ),
        yc.WithInternalCA(), // append Yandex Cloud certificates
    )
    if err != nil {
        panic(err)
    }
    defer func() { 
        _ = db.Close(ctx) 
    }()
}

public void work(String connectionString, Path saKeyPath) {
    AuthProvider authProvider = CloudAuthProvider.newAuthProvider(
        ApiKeyCredentialProvider.builder()
            .fromFile(saKeyPath)
            .build()
    );
    GrpcTransport transport = GrpcTransport.forConnectionString(connectionString)
            .withAuthProvider(authProvider)
            .build();
    TableClient tableClient = TableClient
        .newClient(GrpcTableRpc.ownTransport(transport))
        .build());
    doWork(tableClient);
    tableClient.close();
