OCPBUGS-112662: OCPBUGS-114882: set disk size on gcd

[patrickdillon]

Set disk size on GCD in order to increase iops. We will also work on changing the default in the installer when using hyperdisk.

Summary by CodeRabbit

• Increase the control-plane disk size to 512 GB for GCD OVN end-to-end tests across supported OpenShift CI configurations.
• Enable the GCP OS disk-size configuration step in the GCD installation chain to increase disk IOPS.

Walkthrough

GCD OVN test configurations now set control-plane disks to 512 GB. The GCD installation configuration chain now includes the GCP OS disk-size step.

Changes

GCD disk sizing

Layer / File(s)	Summary
Set GCD control-plane disk size ci-operator/config/openshift/installer/..., ci-operator/config/openshift/release/...	GCD OVN test configurations set CONTROL_PLANE_DISK_SIZEGB to 512.
Wire the disk-size installation step ci-operator/step-registry/ipi/conf/gcd/ipi-conf-gcd-chain.yaml	The GCD installation configuration chain includes ipi-conf-gcp-osdisk-disksize.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 0f82c

The PR changes CI configuration, and the corresponding generated metadata and Prow job definitions still need regeneration and validation. This is a bounded merge-readiness follow-up requiring owner attention, with no higher-impact risk identified.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (7 skipped: 7 unsupported.)

Full details: Stable And Deterministic Test Names

Explanation

PASS. The pull request changes only static YAML configuration values (CONTROL_PLANE_DISK_SIZEGB: "512") and adds the ipi-conf-gcp-osdisk-disksize chain reference. The commit diff adds no Ginkgo title declarations or dynamic test-title interpolation. No explicit stable-name failure condition is introduced.

Full details: Test Structure And Quality

Explanation

The pull request changes only CI YAML configuration. It adds CONTROL_PLANE_DISK_SIZEGB: "512" to GCD test configurations and adds the existing ipi-conf-gcp-osdisk-disksize step to the GCD configuration chain. It does not add or modify Ginkgo It blocks, cluster-resource setup or cleanup, waits, or assertions, so the stated test-structure requirements are not implicated.

Full details: Microshift Test Compatibility

Explanation

PASS: The pull request changes only CI YAML configuration. The exact patch adds CONTROL_PLANE_DISK_SIZEGB: "512" and the ipi-conf-gcp-osdisk-disksize step. It adds no Ginkgo declarations or e2e test source, so the MicroShift test compatibility check does not apply.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The pull request changes only CI YAML configuration. It adds CONTROL_PLANE_DISK_SIZEGB: "512" to GCD test jobs and adds the existing ipi-conf-gcp-osdisk-disksize step. The committed diff adds no Ginkgo e2e tests or It(), Describe(), Context(), or When() constructs, so the SNO compatibility check is not applicable.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS. The pull request changes only CI test environment variables and adds the existing ipi-conf-gcp-osdisk-disksize configuration step. That step writes controlPlane.platform.gcp.osDisk.diskSizeGB to install-config.yaml; it does not add deployment manifests, operator code, controllers, replicas, affinity, topology spread, node selectors, tolerations, or PDBs. No topology-related scheduling constraint is introduced.

Full details: Ote Binary Stdout Contract

Explanation

PASS. The pull request changes only seven YAML files. The changes add CONTROL_PLANE_DISK_SIZEGB: "512" and reference the existing ipi-conf-gcp-osdisk-disksize step. No Go or OTE binary source changed, and no process-level main(), suite setup, logging, or stdout code was introduced.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS. The pull request changes only CI YAML configuration: it adds CONTROL_PLANE_DISK_SIZEGB: "512" and inserts the existing ipi-conf-gcp-osdisk-disksize configuration step. The diff adds no Ginkgo tests or test code, and it introduces no IPv4 addresses, IP parsing, URLs, public hosts, registries, or external service connections. The custom check is therefore not applicable.

Full details: No-Weak-Crypto

Explanation

The pull request changes only GCD disk-size configuration and adds the existing ipi-conf-gcp-osdisk-disksize step. The added lines contain no MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, custom cryptography, or secret/token comparisons. The referenced step only writes diskSizeGB values to install-config.yaml; it does not perform cryptographic operations.

Full details: Container-Privileges

Explanation

PASS. The pull request adds only CONTROL_PLANE_DISK_SIZEGB: "512" and one reference to ipi-conf-gcp-osdisk-disksize. No added line contains privileged: true, host namespace settings, SYS_ADMIN, allowPrivilegeEscalation: true, or an explicit root setting. The referenced step only updates install-config.yaml disk-size fields and contains no privilege-related declarations.

Full details: No-Sensitive-Data-In-Logs

Explanation

PASS. The pull request adds only CONTROL_PLANE_DISK_SIZEGB: "512" and activates the existing ipi-conf-gcp-osdisk-disksize step. That step logs disk-size variables and the compute, controlPlane, and platform sections of install-config.yaml; the traced GCD configuration contains disk, machine, project, and region settings, not passwords, tokens, API keys, PII, session IDs, or hostnames. No new sensitive logging was introduced.
