 Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the `extraEnvVarsCM` or the `extraEnvVarsSecret` values.

+### Using an external config server
+
+It is possible to not deploy any shards or a config server. For example, it is possible to simply deploy `mongos` instances that point to an external MongoDB sharded database. If that is the case, set the `configsvr.external.host` and `configsvr.external.replicasetName` for the mongos instances to connect. For authentication, set the `configsvr.external.rootPassword` and `configsvr.external.replicasetKey` values.

 ## Persistence

 The [Bitnami MongoDB](https://github.com/bitnami/bitnami-docker-mongodb-sharded) image stores the MongoDB data and configurations at the `/bitnami/mongodb` path of the container.
