Use Data on SSD With Aerospike on Kubernetes

Overview

The following storage configuration sets up the Aerospike cluster to store namespace data on a provisioned SSD storage device.

For more information on storing namespace data on SSD and other storage configurations, see the Aerospike documentation for namespace storage configuration.

Configure SSD storage

1. Add the following storage-specific configuration to the Aerospike cluster’s custom resource (CR) file.

     storage:
       filesystemVolumePolicy:
         initMethod: deleteFiles
         cascadeDelete: true
       blockVolumePolicy:
         cascadeDelete: true
       volumes:
         - name: workdir
           aerospike:
             path: /opt/aerospike
           source:
             persistentVolume:
               storageClass: ssd
               volumeMode: Filesystem
               size: 1Gi
         - name: ns
           aerospike:
             path: /test/dev/xvdf
           source:
             persistentVolume:
               storageClass: ssd
               volumeMode: Block
               size: 5Gi
         - name: aerospike-config-secret
           source:
             secret:
               secretName: aerospike-secret
           aerospike:
             path: /etc/aerospike/secret
     ...
     aerospikeConfig:
       service:
         feature-key-file: /etc/aerospike/secret/features.conf
       security: {}
       namespaces:
         - name: test
           replication-factor: 2
           storage-engine:
             type: device
             devices:
               - /test/dev/xvdf

   For the full CR file, see the example SSD storage cluster CR.

   This and other example CRs are in the main Aerospike Kubernetes Operator repository.

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

   kubectl apply -f aerospike-cluster.yaml
