Question

Connecting to Managed Postgres Database / what should I do with .crt file?

I’m in the process of switching over to a managed Postgres database. I’m using the node-postgres library and I was able to connect to the managed db from my node app using this code:

const pool = new Pool({
  ssl: {
    rejectUnauthorized: false
  }
});

I assume having ‘rejectUnauthorized: false’ isn’t a best practice for keeping my database secure. I see that there is a .crt file that I can download from the managed postgres admin page. Am I supposed to do something with this file in order to get my node app to connect to the database without having to set rejectUnauthorised to false?

Also of note, I am running Ubuntu 20.04 on my server. Without the above code, I get this error in the terminal:

(node:8863) UnhandledPromiseRejectionWarning: Error: self signed certificate in certificate chain
    at TLSSocket.onConnectSecure (_tls_wrap.js:1501:34)
    at TLSSocket.emit (events.js:315:20)
    at TLSSocket._finishInit (_tls_wrap.js:936:8)
    at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:710:12)

Any advice would be greatly appreciated.

Hello,

To use the ca-certificate file, You will need to download the ca-certificate from the cloud UI and place it the file path referenced in your code.

When you configure your client applications, you can use the certificate’s location on your local system. Each client application is configured differently, so check the documentation for the tool you’re using for more detail on setting up SSL connections.

Hope that this helps. Regards, Priyanka
