ArangoDB v3.11 is under development and not released yet.

This documentation is not final and potentially incomplete.


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.
