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.

Setup

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
