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.
