 Retrieve the instance IP and port of your Managed Database from the console, under the [Managed Database section](https://console.scaleway.com/rdb/instances).
 Use the following command to connect to your database. When prompted for a password, you can find it by running `terraform output -json`.

 Here are some possible extensions to this basic example:

+ - Replace the simple proposed logic with your own. What about counting how many times some keywords (e.g: copilot, serverless, microservice) appear in Hacker News articles?
  - Define multiple cron triggers for different websites and pass the website as an argument to the function. Or, create multiple functions that feed the same queue.
  - Use a [Serverless Container](/serverless/containers/quickstart/) instead of the consumer function, and use a command line tool such as `htmldoc` or `pandoc` to convert the scraped articles to PDF and upload the result to a [Scaleway Object Storage](/storage/object/quickstart/) S3 bucket.
  - Replace the Managed Database for PostgreSQL with a [Scaleway Serverless Database](/serverless/sql-databases/quickstart/), so that all the infrastructure lives in the serverless ecosystem! *Note that at the moment there is no Terraform support for Serverless Database, hence the choice here to use Managed Database for PostgreSQL*.
