Connect to PostgreSQL Addon


Apps on Cloudron use an internal PostgreSQL database (addon). For security reasons, the database is only accessible from inside the server and cannot be accessed directly from outside. Instead, the database is accessed using an SSH tunnel to the server.

In this guide, we will see how to connect to the PostgreSQL addon database from outside (say, your laptop/PC).

Database credentials

To get the database credentials, open the Web terminal of an app and run env | grep CLOUDRON_POSTGRESQL. Make a note of the credentials. Note that each app has it's own separate database and thus it's own database credentials.

Internal IP Address

Next, SSH into the server and get the IP address of the internal PostgreSQL server. You can do this by running docker inspect postgresql | grep IPAddress. In the output below, is the IP of the PostgreSQL server. This database server IP is the same for all apps. However, it's possible that this IP changes over a Cloudron update.

root@my:~# docker inspect postgresql | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "",
                    "IPAddress": "",

DB Clients


DBeaver is a free multi-platform database tool for developers, database administrators. You can download it here.

Create a new PostgreSQL connection in DBeaver.

Fill up the values gathered in the steps above:

Configure SSH tunnel by clicking on the SSH tab:

You should now be able to view the database:
