# Amazon RDS 1. Sign in to the AWS Management Console and open the Amazon RDS console at\ 2. In the navigation panel, choose **Databases** to display a list of your DB instances.

3. Click on the DB you want to sync. 4. On the **Connectivity & security tab**, copy the endpoint and the port number.

5. Then click on the **Configuration** tab and view the **Master username** and **DB name** values. \ If the DB name is empty as it is the case here, then use **'postgres'** as DB name.\ The password was set when the database was originally created. Please ask whoever set up the database for the connection password.

5. Use this template for the connection string and replace the element with your values ``` postgresql://USERNAME:YOUR_PASSWORD@ENDPOINT:PORT/DB_NAME ``` 7. Paste the connection string into Stacksync

If your database is in a **private subnet** and doesn't have any way to access it from internet currently, you can set up a jumpbox / bastion host to allow Stacksync to access your database using this tutorial: {% content-ref url="/pages/WtisCNpQmZWu8Z4PAEXS" %} [Access a Private AWS RDS Instance via a Jumpbox](/two-way-sync/connectors/setup-options/ssh-tunneling/access-a-private-aws-rds-instance-via-a-jumpbox.md) {% endcontent-ref %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
