Summary

Convert ComputeInstanceDisk.storage_tier from a bare string to a typed StorageTierReference {id, name} message, aligning it with every other resource pointer on ComputeInstance (instance_type, subnet, virtual_network, template) that was converted in migration 90.

Jira: OSAC-4694

Changes

Commit 1 — Proto + validation + server + reconciler

  • Define StorageTierReference message in private proto (public auto-generated)
  • Retype ComputeInstanceDisk.storage_tier from optional string to optional StorageTierReference
  • Register StorageTierReference lookup in reference_lookups.go using RegisterDAOLookup
  • Remove hand-rolled validateStorageTiers() — reference-validator framework replaces it
  • Add storageTierRefsEqual() for immutability comparison by id
  • Update validateDisk() in spec_defaults.go for reference-aware checks
  • Update reconciler: .GetStorageTier().GetStorageTier().GetName() for CRD mapping
  • Fix all unit test fixtures

Commit 2 — DB migration 112

  • Backfill boot_disk.storage_tier and additional_disks[].storage_tier from string to {id, name} object
  • Covers both compute_instances and archived_compute_instances
  • Guarded with jsonb_typeof(...) = 'string' for idempotency
  • Migration test with 5 scenarios (boot disk, additional disks, skip existing, orphan fallback, archived)

Commit 3 — CLI + E2E tests

  • Update CLI builders to use StorageTierReference_builder{Name: value}
  • Update 5 E2E Python test files to use {"name": tier} format

Testing

  • buf lint passes
  • go build ./cmd/fulfillment-service && go build ./cmd/osac succeeds
  • 117 unit tests pass (ginkgo run internal/utils internal/controllers/computeinstance)
  • Migration test: 5 scenarios covering boot disk, additional disks, idempotency, orphan tiers, and archived rows
  • E2E test sources updated (live execution pending)

Backward Compatibility

This is a wire-incompatible proto change. Callers that previously sent "storage_tier": "fast" must now send "storage_tier": {"name": "fast"}. The server auto-resolves the id field when only name is provided.

Summary

API surface

  • Changed ComputeInstanceDisk.storage_tier from an optional string to StorageTierReference.
  • Added StorageTierReference.id and StorageTierReference.name.
  • The server resolves the tier ID when the client provides only name.

Validation and controllers

  • Registered public and private storage-tier reference lookups.
  • Removed the hand-written storage-tier existence validator.
  • Validated references that contain a non-empty id or name.
  • Compared storage-tier references by ID first, then by name.
  • Updated reconciler mapping to use the reference name.

Database

  • Added migration 112.
  • Converted storage-tier names to reference objects in active and archived compute instances.
  • Preserved existing reference objects.
  • Used a name-only reference when the tier is missing or soft-deleted.
  • Added idempotency guards and preserved additional-disk order.

Tests and E2E

  • Updated unit tests, migration tests, CLI helpers, integration tests, and E2E payloads.
  • Added migration coverage for active records, archived records, existing references, and orphan tiers.
  • Reported linting, builds, 117 unit tests, and five migration scenarios.
  • Live E2E execution remains pending.

Backward compatibility

This change is wire-incompatible. Clients must send {"name": "fast"} instead of "fast" for storage_tier. Migration 112 updates existing database records. The server accepts unresolved name references at the server layer because reference validation runs in the gRPC interceptor.

Risk classification

risk:ask — The change modifies a public wire type, rewrites active and archived records through a database migration, and changes validation ownership from server logic to reference validation. It does not qualify as risk:show because it affects API compatibility and persisted data, not only presentation. It is not close to risk:ship because the API and database changes require explicit review.

Walkthrough

Compute instance disk storage tiers now use StorageTierReference objects with optional IDs and names. The change updates protobuf contracts, request handling, reference validation, migration 112, immutability checks, and test payloads.

Changes

Storage tier reference conversion

Layer / File(s) Summary
Reference contract and request flow
fulfillment-service/proto/*/compute_instance_common_type.proto, fulfillment-service/internal/cmd/..., fulfillment-service/internal/controllers/..., fulfillment-service/internal/cmd/service/...
ComputeInstanceDisk.storage_tier now uses StorageTierReference. CLI builders create name references. Reconciliation reads the reference name. Reference-validator lookups include storage tiers.
Persisted data conversion
fulfillment-service/internal/database/migrations/112_*
Migration 112 converts string storage tiers in active and archived records. Matching tiers receive IDs. Unmatched tiers become name-only references. Existing objects remain unchanged. Additional disk order is preserved.
Server validation and immutability
fulfillment-service/internal/servers/private_compute_instances_server.go, fulfillment-service/internal/utils/spec_defaults.go, fulfillment-service/internal/servers/*_test.go, fulfillment-service/internal/utils/*_test.go
Server-level existence validation is removed. Required-field validation accepts a non-empty reference ID or name. Immutability compares IDs when available and otherwise compares names.
Client payload and regression coverage
tests/e2e/catalog/*, tests/e2e/core/*, tests/e2e/references/*, tests/e2e/vmaas/*, fulfillment-service/it/*
Compute instance payloads send storage tiers as objects with name or id. Additional-disk validation accepts string and reference-object inputs.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 1f777

Compute instance disk storage tiers now use structured references, with lookup registration and integration payloads updated accordingly. No concrete merge-blocking risk remains.

Compare the storage tier name in these assertions.

GetStorageTier() now returns *privatev1.StorageTierReference. Each Equal("standard") comparison therefore fails. Assert GetStorageTier().GetName() instead.

Send the empty tier as a reference object.

When storage_tier == "", this emits a scalar for a StorageTierReference field. The request fails during protobuf JSON decoding instead of testing the required-field error. Set this value to {"name": storage_tier}.

Proposed fix
-        additional_disk["storage_tier"] = storage_tier
+        additional_disk["storage_tier"] = {"name": storage_tier}

Replace the bare `optional string storage_tier` field on
ComputeInstanceDisk with a typed `optional StorageTierReference
storage_tier` message containing `{string id, string name}`, aligning
disk storage tier pointers with every other resource reference in the
API (instance_type, subnet, template, etc.).

Key changes:
- Define StorageTierReference in private and public protos
- Register StorageTierReference lookup in reference_lookups.go
- Remove hand-rolled validateStorageTiers() — the reference validator
  interceptor now handles existence checks
- Update validateDisk() to use reference-aware checks
- Add storageTierRefsEqual() for immutability comparison (id-first
  with name fallback)
- Update reconciler to extract .GetName() for CRD mapping
- Update CLI builders to use StorageTierReference_builder
- Fix all unit tests to use typed references

Write migration 112 to convert the storage_tier field on
ComputeInstanceDisk from a bare string (tier name) to a typed
reference object {"id": "...", "name": "..."}.

Backfills both compute_instances and archived_compute_instances
tables, handling boot_disk and additional_disks array elements.
Joins against the storage_tiers table to resolve name → id;
falls back to name-only when the tier no longer exists.
Guards with jsonb_typeof = 'string' to skip already-converted rows.
