Google GKE Cluster Storage Initialization

Integration with Google GKE and storage initialization configuration.

Constraints and Limitations

The minimum capacity for a Persistent Volume Claim (PVC) of the default file storage type is 1TB. If you specify a capacity less than 1TB when creating, it will be automatically resized to 1TB.
Default file storage has capacity limits that can be expanded through a support request.
Creating and deleting default file storage takes a longer time. If it stays in the “Creating” state for a long time, please be patient.

When creating a cluster, please check the options Enable Compute Engine Persistent Disk CSI Driver and Enable Filestore CSI Driver under the Clusters > Features section on the Google Cloud Platform.
Please enable Cloud Filestore API and Google Kubernetes Engine API on the Google Cloud Platform. Refer to Accessing Filestore instances using the Filestore CSI driver for details.
Adjust the regional file storage quota on Google Cloud Platform. Refer to Resource Usage Quotas and Permissions for details.
If you have already created a GKE cluster, access the GKE cluster ; if you haven’t created a GKE cluster, create a Google GKE cluster .

Go to Platform Management, click Storage Management > Storage Class in the left navigation bar.
Click the Update Project button on the right of the storage class named standard-rwx or standard-rwo.

Tip: After accessing the GKE cluster, default storage classes are generated as follows. It is recommended to use the standard-rwx storage class for file storage and the standard-rwo storage class for block storage. Refer to Explanation of Default Storage Classes for details.
Choose how to Assign Projects as needed, then click Update to assign the standard-rwx or standard-rwo storage class to projects for use.

Tip: If the default storage class does not meet your requirements, you can create a new storage class and modify the relevant parameters as needed, as described in Explanation of Storage Class Parameters .

Storage Class Name	Storage Class Type	Description
(Recommended) standard-rwx	File Storage	Uses Basic HDD Filestore Service Tier .
(Recommended) standard-rwo	Block Storage	Uses balanced persistent disk.
premium-rwx	File Storage	Uses Basic SSD Filestore Service Tier .
premium-rwo	Block Storage	SSD persistent disk.
enterprise-rwx	File Storage	Uses Enterprise Filestore Service Tier .
enterprise-multishare-rwx	File Storage	Uses Enterprise Filestore Service Tier . Refer to Filestore multiple share for Google Kubernetes Engine .
