How to manage related applications
Relations to new applications are supported via the “postgresql_client” interface. To create a relation:
juju relate postgresql-k8s application
To remove a relation:
juju remove-relation postgresql-k8s application
We have also added support for the database legacy relation from the original version of the charm via the
pgsql interface. Please note that these interface is deprecated.
juju relate postgresql-k8s:db mattermost-k8s:db
Also extended permissions can be requested using
juju relate postgresql-k8s:db-admin mattermost-k8s:db
Rotate applications password
To rotate the passwords of users created for related applications, the relation should be removed and related again. That process will generate a new user and password for the application.
juju remove-relation application postgresql-k8s juju add-relation application postgresql-k8s
Internal operator user
The operator user is used internally by the Charmed PostgreSQL Operator, the
set-password action can be used to rotate its password.
- To set a specific password for the operator user
juju run-action postgresql-k8s/leader set-password password=<password> --wait
- To randomly generate a password for the operator user
juju run-action postgresql-k8s/leader set-password --wait
