User Story

As a user of OpenShift on GCP I want to be able to specify pd-balanced disk types so that I can make use of the different disk options supported on GCP

Background

Based on the spike, this should be relatively straightforward to support.

PD balanaced is an additional type on top of the SSD and standard types we already support. We already have a field for users to specify which type they want so uses will be able to specify this new type as well

Steps

• Ensure GCP SDK is bumped to latest version
• Ensure validation in webhooks allows new disk type
• Ensure there are no other prerequisites for pd-balanced disks
• Manual testing to ensure pd-balanced disks work as expected

Stakeholders

• Cluster Infra

Definition of Done

• PR is merged to allow PD Balanced disks within machine-api-provider-gcp

• Docs

• We will need to update the allowed disk types within the machineset docs

• Testing

• Add new MachineSet with pd-balanced disk, check machines can be created, check on gcp console that disk was created correctly.
