PostgreSQL
Learn how to dynamically generate PostgreSQL database users.
The Hanzo KMS PostgreSQL dynamic secret allows you to generate PostgreSQL database credentials on demand based on configured role.
Prerequisite
Create a user with the required permission in your SQL instance. This user will be used to create new accounts on-demand.
Set up Dynamic Secrets with PostgreSQL
Open the Secret Overview dashboard and select the environment in which you would like to add a dynamic secret.
Name by which you want the secret to be referenced
Default time-to-live for a generated secret (it is possible to modify this value after a secret is generated)
Maximum time-to-live for a generated secret
List of key/value metadata pairs
Choose the service you want to generate dynamic secrets for. This must be selected as PostgreSQL.
Database host
Database port
Username that will be used to create dynamic secrets
Password that will be used to create dynamic secrets
Name of the database for which you want to create dynamic secrets
A CA may be required if your DB requires it for incoming connections. AWS RDS instances with default settings will requires a CA which can be downloaded here.
If you want to provide specific privileges for the generated dynamic credentials, you can modify the SQL statement to your needs. This is useful if you want to only give access to a specific table(s).
After submitting the form, you will see a dynamic secret created in the dashboard.
If this step fails, you may have to add the CA certificate.
Once you've successfully configured the dynamic secret, you're ready to generate on-demand credentials. To do this, simply click on the 'Generate' button which appears when hovering over the dynamic secret item. Alternatively, you can initiate the creation of a new lease by selecting 'New Lease' from the dynamic secret lease list section.
When generating these secrets, it's important to specify a Time-to-Live (TTL) duration. This will dictate how long the credentials are valid for.
Ensure that the TTL for the lease falls within the maximum TTL defined when configuring the dynamic secret.
Once you click the Submit button, a new secret lease will be generated and the credentials for it will be shown to you.
Audit or Revoke Leases
Once you have created one or more leases, you will be able to access them by clicking on the respective dynamic secret item on the dashboard. This will allow you to see the expiration time of the lease or delete the lease before it's set time to live.
Renew Leases
To extend the life of the generated dynamic secret leases past its initial time to live, simply click on the Renew button as illustrated below.
Lease renewals cannot exceed the maximum TTL set when configuring the dynamic secret
