How to manage client applications
Integrations (formerly “relations”) are connections between two applications with compatible endpoints. These connections simplify the creation and management of users, passwords, and other shared data.
Create an integration
Integrations with new applications are supported via the postgresql_client interface.
To create an integration, run
juju integrate postgresql <application>
To remove an integration to an application:
juju remove-relation postgresql <application>
Legacy pgsql interface
We have also added support for the database legacy relation from the original version of the charm via the pgsql interface. Note that this interface is deprecated.
juju integrate postgresql:db <application>
Extended permissions can be requested using the db-admin endpoint:
juju integrate postgresql:db-admin <application>
Rotate application passwords
To rotate the passwords of users created for integrated applications, the integration should be removed and integrated again. This process will generate a new user and password for the application.
juju remove-relation <application> postgresql
juju integrate <application> postgresql
Internal operator user
The operator user is used internally by the Charmed PostgreSQL VM Operator. The set-password action can be used to rotate its password.
To set a specific password for the operator user, run
juju run postgresql/leader set-password password=<password>
To randomly generate a password for the operator user, run
juju run postgresql/leader set-password
