Vertical Scale Elasticsearch Topology Cluster
This guide will show you how to use KubeDB Ops-manager operator to update the resources of a Elasticsearch topology cluster.
Before You Begin
At first, you need to have a Kubernetes cluster, and the
kubectlcommand-line tool must be configured to communicate with your cluster. If you do not already have a cluster, you can create one by using kind.Install
KubeDBProvisioner and Ops-manager operator in your cluster following the steps here.You should be familiar with the following
KubeDBconcepts:
To keep everything isolated, we are going to use a separate namespace called demo throughout this tutorial.
$ kubectl create ns demo
namespace/demo created
Note: YAML files used in this tutorial are stored in docs/examples/Elasticsearch directory of kubedb/docs repository.
Apply Vertical Scaling on Topology Cluster
Here, we are going to deploy a Elasticsearch topology cluster using a supported version by KubeDB operator. Then we are going to apply vertical scaling on it.
Prepare Elasticsearch Topology Cluster
Now, we are going to deploy a Elasticsearch topology cluster database with version xpack-8.11.1.
Deploy Elasticsearch Topology Cluster
In this section, we are going to deploy a Elasticsearch topology cluster. Then, in the next section we will update the resources of the database using ElasticsearchOpsRequest CRD. Below is the YAML of the Elasticsearch CR that we are going to create,
apiVersion: kubedb.com/v1
kind: Elasticsearch
metadata:
name: es-cluster
namespace: demo
spec:
enableSSL: true
version: xpack-8.11.1
storageType: Durable
topology:
master:
replicas: 3
storage:
storageClassName: "standard"
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
data:
replicas: 3
storage:
storageClassName: "standard"
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
ingest:
replicas: 3
storage:
storageClassName: "standard"
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
Let’s create the Elasticsearch CR we have shown above,
$ kubectl create -f https://github.com/kubedb/docs/raw/v2025.10.17/docs/examples/elasticsearch/scaling/Elasticsearch-topology.yaml
Elasticsearch.kubedb.com/es-cluster created
Now, wait until es-cluster has status Ready. i.e,
$ kubectl get es -n demo -w
NAME VERSION STATUS AGE
es-cluster xpack-8.11.1 Ready 53m
Let’s check the Pod containers resources for both data,ingest and master of the Elasticsearch topology cluster. Run the following command to get the resources of the broker and controller containers of the Elasticsearch topology cluster
$ kubectl get pod -n demo es-cluster-data-0 -o json | jq '.spec.containers[].resources'
{
"limits": {
"memory": "1536Mi"
},
"requests": {
"cpu": "500m",
"memory": "1536Mi"
}
}
$ kubectl get pod -n demo es-cluster-ingest-0 -o json | jq '.spec.containers[].resources'
{
"limits": {
"memory": "1536Mi"
},
"requests": {
"cpu": "500m",
"memory": "1536Mi"
}
}
$ kubectl get pod -n demo es-cluster-master-0 -o json | jq '.spec.containers[].resources'
{
"limits": {
"memory": "1536Mi"
},
"requests": {
"cpu": "500m",
"memory": "1536Mi"
}
}
This is the default resources of the Elasticsearch topology cluster set by the KubeDB operator.
We are now ready to apply the ElasticsearchOpsRequest CR to update the resources of this database.
Vertical Scaling
Here, we are going to update the resources of the topology cluster to meet the desired resources after scaling.
Create ElasticsearchOpsRequest
In order to update the resources of the database, we have to create a ElasticsearchOpsRequest CR with our desired resources. Below is the YAML of the ElasticsearchOpsRequest CR that we are going to create,
apiVersion: ops.kubedb.com/v1alpha1
kind: ElasticsearchOpsRequest
metadata:
name: vscale-topology
namespace: demo
spec:
type: VerticalScaling
databaseRef:
name: es-cluster
verticalScaling:
master:
resources:
limits:
cpu: 750m
memory: 800Mi
data:
resources:
requests:
cpu: 760m
memory: 900Mi
ingest:
resources:
limits:
cpu: 900m
memory: 1.2Gi
requests:
cpu: 800m
memory: 1Gi
Here,
spec.databaseRef.namespecifies that we are performing vertical scaling operation ones-clustercluster.spec.typespecifies that we are performingVerticalScalingon Elasticsearch.spec.VerticalScaling.nodespecifies the desired resources after scaling.
Let’s create the ElasticsearchOpsRequest CR we have shown above,
$ kubectl apply -f https://github.com/kubedb/docs/raw/v2025.10.17/docs/examples/elasticsearch/scaling/vertical/Elasticsearch-vertical-scaling-topology.yaml
Elasticsearchopsrequest.ops.kubedb.com/vscale-topology created
Verify Elasticsearch Topology cluster resources updated successfully
If everything goes well, KubeDB Ops-manager operator will update the resources of Elasticsearch object and related PetSets and Pods.
Let’s wait for ElasticsearchOpsRequest to be Successful. Run the following command to watch ElasticsearchOpsRequest CR,
$ kubectl get elasticsearchopsrequest -n demo
NAME TYPE STATUS AGE
vscale-topology VerticalScaling Successful 18m
We can see from the above output that the ElasticsearchOpsRequest has succeeded. If we describe the ElasticsearchOpsRequest we will get an overview of the steps that were followed to scale the cluster.
$ kubectl describe Elasticsearchopsrequest -n demo vscale-topology

Now, we are going to verify from one of the Pod yaml whether the resources of the topology cluster has updated to meet up the desired state, Let’s check,
$ kubectl get pod -n demo es-cluster-ingest-0 -o json | jq '.spec.containers[].resources'
{
"limits": {
"cpu": "900m",
"memory": "1288490188800m"
},
"requests": {
"cpu": "800m",
"memory": "1Gi"
}
}
$ kubectl get pod -n demo es-cluster-data-0 -o json | jq '.spec.containers[].resources'
{
"limits": {
"memory": "900Mi"
},
"requests": {
"cpu": "760m",
"memory": "900Mi"
}
}
$ kubectl get pod -n demo es-cluster-master-0 -o json | jq '.spec.containers[].resources'
{
"limits": {
"cpu": "750m",
"memory": "800Mi"
},
"requests": {
"cpu": "750m",
"memory": "800Mi"
}
}
The above output verifies that we have successfully scaled up the resources of the Elasticsearch topology cluster.
Cleaning Up
To clean up the Kubernetes resources created by this tutorial, run:
kubectl delete es -n demo es-cluster
kubectl delete Elasticsearchopsrequest -n demo vscale-topology
kubectl delete ns demo
