Spectro Storage Pack(s) helps provision StorageClasses on the Kubernetes infrastructure. StorageClasses in Kubernetes are essentially blueprints that abstract away the underlying storage provider, as well as other parameters, like disk-type (e.g.; solid-state vs standard disks).
Storage classes are cloud-specific and are detailed below:
| Name | Supported Values | Default Value | Description |
|---|---|---|---|
| storageType | gp2, sc1, st1, io1 | gp2 | AWS Volume type to be used |
| reclaimPolicy | Delete, Retain | Delete | Defines whether volumes will be retained or deleted |
| allowVolumeExpansion | true, false | true | Flag to allow resizing volume |
| isDefaultClass | true, false | true | Flag to denote if this StorageClass will be the default |
| volumeBindingMode | WaitForFirstConsumer, Immediate | WaitForFirstConsumer | Controls when volumeBinding and dynamic provisioning should happen |
