Overview
KubeDB is the Kubernetes Native Database Management Solution which simplifies and automates routine database tasks such as Provisioning, Monitoring, Upgrading, Patching, Scaling, Volume Expansion, Backup, Recovery, Failure detection, and Repair for various popular databases on private and public clouds. The databases supported by KubeDB include MongoDB, Elasticsearch, MySQL, MariaDB, Redis, PostgreSQL, FerretDB, SingleStore, Percona XtraDB, and Memcached. Additionally, KubeDB also supports ProxySQL, PgBouncer, Pgpool, ZooKeeper and the streaming platform Kafka, RabbitMQ. You can find the guides to all the supported databases in KubeDB . In this tutorial we will deploy SingleStore in Amazon Elastic Kubernetes Service (Amazon EKS). We will cover the following steps:
- Install KubeDB
- Deploy SingleStore Cluster
- Read/Write Sample Data
- Access SingleStore Studio UI
Get Cluster ID
We need the cluster ID to get the KubeDB License. To get cluster ID, we can run the following command:
$ kubectl get ns kube-system -o jsonpath='{.metadata.uid}'
8e336615-0dbb-4ae8-b72f-2e7ec34c399d
Get License
Go to Appscode License Server to get the license.txt file. For this tutorial we will use KubeDB.
Install KubeDB
We will use helm to install KubeDB. Please install helm here
if it is not already installed.
Now, let’s install KubeDB.

Create SingleStore License Secret
First, we need to create a namespace for our SingleStore deployment. Open your terminal and run the following command:
$ kubectl create namespace demo
namespace/demo created
Next, you’ll need a SingleStore license
to create the SingleStore database. Ensure that you have acquired a license, then create a secret to store your license information. Run the following command, replacing your-license-here with your actual license key:
$ kubectl create secret generic -n demo license-secret \
--from-literal=username=license \
--from-literal=password='your-license-here'
With the namespace and license secret created, we can now deploy the SingleStore cluster.
Deploy SingleStore Cluster
Here is the yaml of the SingleStore CR we are going to use:
apiVersion: kubedb.com/v1alpha2
kind: Singlestore
metadata:
name: singlestore-cluster
namespace: demo
spec:
version: "8.5.7"
topology:
aggregator:
replicas: 2
podTemplate:
spec:
containers:
- name: singlestore
resources:
limits:
memory: "2Gi"
cpu: "600m"
requests:
memory: "2Gi"
cpu: "600m"
storage:
storageClassName: "gp2"
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
leaf:
replicas: 3
podTemplate:
spec:
containers:

storage:
storageClassName: "gp2"
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 10Gi
licenseSecret:
name: license-secret
storageType: Durable
deletionPolicy: WipeOut
Let’s save this yaml configuration into singlestore-cluster.yaml
Then create the above SingleStore CR,
$ kubectl apply -f singlestore-cluster.yaml
singlestore.kubedb.com/singlestore-cluster created
In this yaml,
- In this yaml we can see in the
spec.versionfield specifies the version of SingleStore. Here, we are using SingleStore8.5.7. You can list the KubeDB supported versions of SingleStore by running$ kubectl get singlestoreversionscommand. spec.topologyrepresents the clustering configuration for SingleStore.spec.topology.aggregator.replicasorspec.topology.leaf.replicasspecifies that the number replicas that will be used for aggregator or leaf.spec.storageTypespecifies the type of storage that will be used for SingleStore database. It can beDurableorEphemeral.spec.storage.storageClassNameis the name of the StorageClass used to provision PVCs.
Once these are handled correctly and the SingleStore cluster is deployed, you will see that the following objects are created:
$ kubectl get all -n demo

NAME TYPE VERSION STATUS AGE
singlestore.kubedb.com/singlestore-cluster kubedb.com/v1alpha2 8.5.7 Ready 4m41s
Let’s check if the database is ready to use,
$ kubectl get singlestore -n demo singlestore-cluster
NAME TYPE VERSION STATUS AGE
singlestore-cluster kubedb.com/v1alpha2 8.5.7 Ready 5m14s
We have successfully deployed SingleStore cluster in Amazon EKS.
Accessing Database Through CLI
To access the database through CLI, we have to get the credentials to access. KubeDB will create Secret and Service for the database singlestore-cluster that we have deployed. Let’s check them using the following commands,
$ kubectl get secret -n demo -l=app.kubernetes.io/instance=singlestore-cluster
NAME TYPE DATA AGE
singlestore-cluster-root-cred kubernetes.io/basic-auth 2 5m56s
$ kubectl get service -n demo -l=app.kubernetes.io/instance=singlestore-cluster
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
singlestore-cluster ClusterIP 10.96.132.208 <none> 3306/TCP,8081/TCP 6m9s
singlestore-cluster-pods ClusterIP None <none> 3306/TCP 6m9s
Now, we are going to use singlestore-cluster-root-cred to get the credentials.
$ kubectl get secrets -n demo singlestore-cluster-root-cred -o jsonpath='{.data.username}' | base64 -d
root
$ kubectl get secrets -n demo singlestore-cluster-root-cred -o jsonpath='{.data.password}' | base64 -d

Insert Sample Data
In this section, we are going to login into our SingleStore database pod and insert some sample data.
$ kubectl exec -it singlestore-cluster-aggregator-0 -n demo -- bash
Defaulted container "singlestore" out of: singlestore, singlestore-coordinator, singlestore-init (init)

We’ve successfully inserted some sample data to our database. More information about Deploy & Manage SingleStore on Kubernetes can be found in Kubernetes SingleStore
Accessing SingleStore Studio UI
Now, we will access the SingleStore Studio UI using port forwarding , which will allow you to manage your SingleStore cluster via a web interface. Run the following command in your terminal, you should see output indicating that port forwarding is active:
$ kubectl port-forward -n demo service/singlestore-cluster 8081
Forwarding from 127.0.0.1:8081 -> 8081
Forwarding from [::1]:8081 -> 8081
Now, the SingleStore Studio UI is accessible at localhost:8081. Open your web browser and navigate to localhost:8081. You will see the SingleStore Studio login panel. Choose the Add Existing Cluster option and click the Next button.
Next, enter your cluster information, then click the Submit button.
Once you have provided all the valid information, you will gain access to the SingleStore Studio.
Congratulations! You have successfully accessed the SingleStore Studio. This interface provides a convenient way to monitor and administer your SingleStore database.
