Epic Goal

• Support pd-balanced disk types for GCP deployments

Why is this important?

• Customers will be able to reduce costs on GCP while using `pd-balanced` disk types with a comparable performance to `pd-ssd` ones.

Scenarios

1. Enable `pd-balanced` disk types when deploying a cluster in GCP. Right now only `pd-ssd` and `pd-standard` are supported.

Overview:

• To enable support for pd-balanced disk types during cluster deployment in Google Cloud Platform (GCP) for Openshift Installer.
• Currently, only pd-ssd and pd-standard disk types are supported.
• `pd-balanced` disks on GCP will offer cost reduction and comparable performance to `pd-ssd` disks, providing increased flexibility and performance for deployments.

Acceptance Criteria:

• The Openshift Installer should be updated to include pd-balanced as a valid disk type option in the installer configuration process.
• When pd-balanced disk type is selected during cluster deployment, the installer should handle the configuration of the disks accordingly.
• CI (Continuous Integration) must be running successfully with tests automated.
• Release Technical Enablement details and documents should be provided.

Done Checklist:

• CI is running, tests are automated, and merged.
• Release Enablement Presentation: [link to Feature Enablement Presentation].
• Upstream code and tests merged: [link to meaningful PR or GitHub Issue].
• Upstream documentation merged: [link to meaningful PR or GitHub Issue].
• Downstream build attached to advisory: [link to errata].
• Test plans in Polarion: [link or reference to Polarion].
• Automated tests merged: [link or reference to automated tests].
• Downstream documentation merged: [link to meaningful PR].

Dependencies:

• Google Cloud Platform Account
• Access to GCP ‘Installer’ Project
• Any required permissions, authentication, access controls or CLI needed to provision pd-balanced disk types should be properly configured.

Testing:

• Develop and conduct test cases and scenarios to verify the proper functioning of pd-balanced disk type implementation.
• Address any bugs or issues identified during testing.

Documentation:

• Update documentation to reflect the support for pd-balanced disk types in GCP deployments.

Success Metrics:

• Successful deployment of Openshift clusters using the pd-balanced disk type in GCP.
• Minimal or no disruption to existing functionality and deployment options.
