Authentication using a service account file
Below are examples of the code for authentication using a service account file in different YDB SDKs.
Go (native)
Go (database/sql)
Java
Node.js
Python
Python (asyncio)
C# (.NET)
PHP
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 db.Close(ctx)
...
}

Loading service account data from a file:
import { Driver, getSACredentialsFromJson, IamAuthService } from 'ydb-sdk';
export async function connect(endpoint: string, database: string, serviceAccountFilename: string) {
const saCredentials = getSACredentialsFromJson(serviceAccountFilename);
const authService = new IamAuthService(saCredentials);
const driver = new Driver({endpoint, database, authService});
const timeout = 10000;
if (!await driver.ready(timeout)) {
console.log(`Driver has not become ready in ${timeout}ms!`);
process.exit(1);
}
console.log('Driver connected')
return driver
}
Loading service account data from a third-party source (for example, a secret storage):
import { Driver, IamAuthService } from 'ydb-sdk';
import { IIamCredentials } from 'ydb-sdk/build/cjs/src/credentials';
export async function connect(endpoint: string, database: string) {
const saCredentials: IIamCredentials = {
serviceAccountId: 'serviceAccountId',
accessKeyId: 'accessKeyId',
privateKey: Buffer.from('-----BEGIN PRIVATE KEY-----\nyJ1yFwJq...'),
iamEndpoint: 'iam.api.cloud.yandex.net:443',
};
const authService = new IamAuthService(saCredentials);
const driver = new Driver({endpoint, database, authService});
const timeout = 10000;
if (!await driver.ready(timeout)) {
console.log(`Driver has not become ready in ${timeout}ms!`);
process.exit(1);
}
console.log('Driver connected')
return driver
}
