Scaling Aerospike on Kubernetes

For this example assume that cluster is deployed using a file named aerospike-cluster.yaml.

Change the spec.size field in the yaml file to scale the cluster up or down to the specified number of pods.

apiVersion: asdb.aerospike.com/v1beta1
kind: AerospikeCluster
metadata:
  name: aerocluster
  namespace: aerospike
spec:
  size: 2
  image: aerospike/aerospike-server-enterprise:6.1.0.1
  .
  .

Use kubectl to apply the change.

kubectl apply -f aerospike-cluster.yaml

Check the pods.

Output:

$ kubectl get pods -n aerospike
NAME          READY   STATUS      RESTARTS   AGE

aerocluster-0-1     1/1     Running     0          3m6s
aerocluster-0-2     1/1     Running     0          30s
aerocluster-0-3     1/1     Running     0          30s
