How to manage related applications
Hint: Use Juju 3. Otherwise replace
juju integratewithjuju relatefor Juju 2.9.
New mysql_client interface:
Relations to new applications are supported via the “mysql_client” interface. To create a relation:
juju integrate mysql application
To remove a relation:
juju remove-relation mysql application
Legacy mysql interface:
We have also added support for the database legacy relation via the mysql interface. Please note that these interface is deprecated.
juju integrate mysql:mysql wordpress
Also extended permissions can be requested using mysql-root edpoint:
juju integrate mysql:mysql-root wordpress
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 mysql
juju integrate application mysql
Internal operator user
The operator user is used internally by the Charmed MySQL Operator, the set-password action can be used to rotate its password.
- To set a specific password for the operator user
juju run mysql/leader set-password password=<password>
- To randomly generate a password for the operator user
juju run mysql/leader set-password
