Modify Aerospike cluster

The Aerospike Kubernetes Operator makes it easier for you to use Aerospike Enterprise clusters on Kubernetes. Instead of making changes to the cluster by hand, you specify changes in the Aerospike cluster CR file, then use kubectl apply to apply these changes. The Operator picks up on the changes and does what it needs to do in order to make them happen.

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

Example Configuration Change

Change the spec.aerospikeConfig.service.proto-fd-max field in the aerocluster CR to 20000

apiVersion: asdb.aerospike.com/v1beta1
kind: AerospikeCluster
metadata:
name: aerocluster
namespace: aerospike
spec:
size: 2
image: aerospike/aerospike-server-enterprise:4.9.0.33
aerospikeConfig:
service:
proto-fd-max: 15000
.
.

Save and exit the CR file, then use kubectl to apply the change.

kubectl apply -f aerospike-cluster.yaml

Check the Pods

Pods will undergo a rolling restart.

$ kubectl get pods -n aerospike
NAME READY STATUS RESTARTS AGE
aerocluster-0-0 1/1 Running 0 3m6s
aerocluster-0-1 1/1 Running 0 3m6s
aerocluster-0-2 1/1 Running 0 30s
aerocluster-0-3 1/1 Terminating 0 30s

After all the pods have restarted, use kubectl describe to get status of the cluster.

Check spec.aerospikeConfig.service.proto-fd-max in status.

$ kubectl -n aerospike describe aerospikecluster aerocluster
Name: aerocluster
Namespace: aerospike
Kind: AerospikeCluster
