# Scaling The ArangoDB Kubernetes Operator supports up and down scaling of the number of dbservers & coordinators. Currently it is not possible to change the number of agents of a cluster. The scale up or down, change the number of servers in the custom resource. E.g. change `spec.dbservers.count` from `3` to `4`. Then apply the updated resource using: ```bash kubectl apply -f yourCustomResourceFile.yaml ``` Inspect the status of the custom resource to monitor the progress of the scaling operation.
