How to manage client connections
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 a client connection to a bare replica set
- Create a client connection to a sharded cluster
- Internal

user
Create a client connection to a bare replica set
To create a client connection to a replica set, simply integrate your client application with a Charmed MongoDB application running in replication mode.
If you do not have a client application that implements this interface, you can use the data-integrator
charm.
To integrate mongodb
with a client application, run:
juju integrate mongodb-k8s <application>
Remove a client connection to a replica set
To remove a client connection and the user associated with it:
juju remove-relation mongodb-k8s <application>
Rotate the client password
To rotate the replica-set client password, the integration should be removed and integrated again:
juju remove-relation <application> mongodb-k8s
juju integrate <application> mongodb-k8s
This process will generate a new user and password for the application.
Create a client connection to a sharded cluster
To create a client connection to a sharded cluster, you must use the Charmed Mongos-K8s router.
To deploy mongos-k8s
and data-integrator
, run:
juju deploy mongos-k8s
juju deploy data-integrator [necessary options]
Wait for mongos-k8s
’s status to be idle
, then integrate it with data-integrator
:
juju integrate mongos-k8s data-integrator
Next, integrate the mongos-k8s
charm to a Charmed MongoDB application running as a config-server:
juju integrate config-server mongos-k8s
Remove a client connection to a sharded cluster
To remove a client connection to a sharded cluster:
juju remove-relation config-server mongos-k8s
Rotate the mongos-k8s
client password
To rotate client passwords, the integration should be removed and integrated again:
juju remove-relation <application> mongos-k8s
juju integrate <application> mongos-k8s
This process will generate a new user and password for the application.
Internal operator user
The operator
(i.e. admin) user is used internally by Charmed MongoDB K8s. To rotate its password, use the set-password
action.
To set a specific password for the operator
user, run:
juju run mongodb-k8s/leader set-password password=<password>
To randomly generate a password for the operator
user, run:
juju run mongodb-k8s/leader set-password
