# 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.
