Scaling
The ArangoDB Kubernetes Operator supports up and down scaling of the number of DB-Servers & 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:
kubectl apply -f yourCustomResourceFile.yaml
Inspect the status of the custom resource to monitor the progress of the scaling operation.
