Hi

Please follow the below steps to connect Postgres Managed database as the data source for google data studio

  1. Downloaded the CA certificate for your DigitalOcean instance from the console ( this will be a Server certificate)

https://docs.digitalocean.com/products/databases/postgresql/how-to/connect/

  1. Generate client public/private keys pairs

https://support.google.com/a/answer/6342198?hl=en

Make sure you have OpenSSL installed on your operating system. OpenSSL will be used to generate client-side public/private key pairs.

openssl genrsa -out rsaprivkey.pem 2048
openssl rsa -in rsaprivkey.pem -pubout -outform DER -out rsapubkey.der
openssl pkcs8 -topk8 -inform PEM -outform DER -in rsaprivkey.pem -out rsaprivkey.der -nocrypt
  1. To connect your DO PostgreSQL as a data source in Data Studio

https://support.google.com/datastudio/answer/7288010?hl=en&ref_topic=7332343#zippy=%2Cin-this-article

  • Select “Data Sources” on the left followed by the blue (+) on the bottom right corner to add a new data source. Please follow the next set of prompts to agree to google terms and conditions.

  • Select “PostgreSQL” as the data source type on the left and proceed to “Authenticate” DigitalOcean PostgreSQL. Follow the next set of steps to authenticate with your Google account.

  • Under the “Basic” settings, input the values for host, port, database, username, and password. (Note: these values can be obtained from the DigitalOcean console)

  • Remember to enable SSL for over-the-wire encryption of data and enter the cert and key files.

  • Finally, click “Authenticate” to authenticate with the DO PostgreSQL database server.

  • After authentication with the database, you can proceed to query data from it

I hope this helps!

For MySQL, refer to the below link :

Will suggest trying without “Enable SSL”.

Hi All,

Note: the private key should be in PKCS8 format, so if you have supplied rsaprivkey.pem; you will get the below error.

“Please make sure that the private key is in PKCS8 format. Error ID: 8dc032ae”

Add PostgreSQL SSL Client Configuration Files as below :

Server certificate: ca-certificate.crt

Client certificate: rsapubkey.der

Client private key: rsaprivkey.der

I hope this helps!!
