How to use gke-boot-disk=pd-ssd disk with GKE Autopilot?-CodePudding

Autopilot makes all decisions about the nodes but, why are all nodes being created with cloud.google.com/gke-boot-disk=pd-standard? Is it possible to all nodes be created with ssd disk? If so, how can it be done?

CodePudding user response：

To be able to use SSDs for your GKE deployment, you need to use the premium-rwo storage class from the Compute Engine persistent disk CSI Driver to provision your volumes. For that, you need to set up the storageClassName field to premium-rwo in your PersistentVolumeClaim in your manifest file (YAML). Here is an example:

# ssd-claim.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: my-volume
spec:
  storageClassName: premium-rwo
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 30Gi

Please use the following GCP GKE’s official documentation as a detailed guide.

Currently, Autopilot managed node does not use SSD as the boot device, it doesn't support local SSD either. This behavior is not amendable.
