📝 WalkthroughWalkthroughThis change adds catalog-backed Ubuntu/PostgreSQL images, engine-version selection, image-drift conditions, and annotation-triggered OS-disk repaving. It updates Harvester integration, bootstrap readiness, PVC tracking, controller reconciliation, image building, unit tests, and end-to-end tests. ChangesBaked image and repave workflow
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to Repave interruptions or cleanup failures can leave stale disks and cause a replacement database disk to restart without the required bootstrap configuration, while the end-to-end validation may falsely pass without confirming that repave occurred. These correctness and recovery risks should be fixed before merging. Sequence Diagram(s)sequenceDiagram

- Around line 120-121: Create a per-build seed directory under KEY_DIR, copy the
shared meta-data into it, and render user-data from the template into that
directory instead of modifying shared http/user-data. Update the Packer
invocation/template variable to use this build-specific seed directory,
preserving independent SSH keys for concurrent builds.
In `@database/internal/catalog/baked_images.go`:
- Around line 80-93: Update LatestBakedImages so the active 24.04 entry uses a
verified revision compatible with every required engine version (15, 16, 17, and
18), or extend the catalog/resolver contract to select revisions by OS and
engine version. Do not mark any revision ValidationValidated unless it has been
built, imported, and smoke-tested; otherwise keep the stream Pending. Add
coverage for the selected revision and each supported engine version.
In `@database/internal/config/types.go`:
- Around line 88-90: Update the ImageNamespace documentation comment to use a
complete sentence that states which images or catalog resources the Harvester
namespace applies to, while preserving the existing explanation that an empty
value makes ResolveVMImage fall back to "default".
In `@database/internal/ensure/defaults_test.go`:
- Around line 48-52: Update TestEffectiveEngineVersionUnsetDefaultsToHighest to
use an unsorted SupportedEngineVersions list, such as {"17", "16"}, while
preserving the expected result of version "17" and ok=true. This ensures
effectiveEngineVersion selects the highest version rather than merely returning
the final catalog entry.
In `@database/internal/ensure/defaults.go`:
- Around line 49-57: The unset-version path in effectiveEngineVersion assumes
SupportedEngineVersions is ascending but does not enforce or verify it. Ensure
the catalog guarantees ascending numeric ordering for every entry by adding a
catalog test that validates the ordering, while preserving the existing
default-to-last-element behavior.
In `@database/internal/ensure/repave.go`:
- Around line 120-131: Update the image-drift condition around
inst.Status.CurrentImageRevision so an empty revision is treated as not
evaluated: set the ImageDrift condition to Unknown using the existing
unresolvable-stream behavior, and skip the OSUpdateAvailable or EngineVersionEOL
reporting paths. Preserve drift evaluation only when CurrentImageRevision is
non-empty.
In `@database/internal/harvester/typed_client.go`:
- Around line 733-737: Update the idempotent branch in SwapVMOSDisk to compare
the current PVC’s harvesterbuilder.AnnotationKeyImageID with the target image
ID, not just StorageClassName. Only return the existing PVC name as a no-op when
the image IDs match; preserve the existing replacement flow when they differ,
even if the storage classes are identical.
In `@database/internal/testutil/harvester.go`:
- Around line 139-150: Update StubHarvester.SwapVMOSDisk so the SwapVMOSDiskNoop
branch returns the unchanged pre-swap PVC name, matching
TypedClient.SwapVMOSDisk, while preserving the existing revision-suffixed name
for non-no-op swaps.
In `@database/test/repave-e2e.sh`:
- Around line 508-509: Update the post-repave assertion using image_drift_status
to require the explicit expected state: ImageDrift must be False with reason
ImageUpToDate, matching the stage1 assertion. Do not accept Unknown or an absent
condition, and replace the contradictory “condition removed” success message
with one describing the up-to-date state.

Did we check whether this causes a conflict with the resource id? When we do the update, the resource ID gets changed and then defer update might fail because of this.
There was a problem hiding this comment.
Two seperate patch types here,
- Status patch uses plain
client.MergeFrom(before)(no optimistic lock). controller-runtime stripsresourceVersionfrom that diff automatically, so this patch has no version precondition at all. - Conditions patch does use an optimistic lock, but it re-
Gets the object fresh right before applying the lock — so it always locks on the current resourceVersion, never a stale one. Conflicts, if any, are retried with backoff.
Therefore no conflict by design using this.
Why r.Update here: AnnotationRepaveTrigger is in ObjectMeta, and DBInstance has a status subresource Status().Patch() can't touch annotations, so clearing it needs a real Update.
We save(line 292)/restore(line294) inst.Status around it because that endpoint echoes back the server's last persisted status into inst, which would otherwise wipe out in-memory status changes made earlier in this reconcile (only the deferred patch at the end makes those durable).
There was a problem hiding this comment.
"controller-runtime strips resourceVersion from that diff automatically." Have we verified this? AFAIU MergeFrom only leaves it out when it has not changed, and the r.Update on line 293 does change it, since the response is decoded back into inst.
Can we check whether status.currentImageRevision still persists on the apply pass?
There was a problem hiding this comment.
Yeah I checked Thats exactly right ,MergeFrom only drops resourceVersion when unchanged. r.Update() on line 293 does change it, so before/after diverge and the status patch can hit a stale RV 409.
Confirmed on a live cluster
osDiskPVCName/currentImageRevision did get dropped on conflict — but the object looked fine after, only because the next reconcile happened to re-derive the same values from Harvester's live disk state (idempotent swap + self-heal), not because the patch actually succeeded.
Root cause
The annotation delete needs a real Update() (status subresource can't touch ObjectMeta), and doing it mid-reconcile bumps RV under the deferred patch's feet.
Fix
Removed the Update() — Status.LastAppliedRepaveTrigger records the trigger instead, through the same deferred patch. No more mid-reconcile RV mutation.
Re-tested E2E, no conflicts, both fields persist correctly now.

Harvester's own VM controller writes to this same VirtualMachine object independently of us — StoreRunStrategy, resource-quota annotation cleanup, and finalizer removal all call vmClient.Update() on it. So a resourceVersion conflict on our Get→mutate→Update here is a real race between two active controllers.
That's why we used RetryOnConflict here.

Does this VirtualMachine object have an owner CR? Does the VM controller create this on behalf of another CR?

Wait for each repave to start before waiting for completion.
Both instances are already available when Lines 819-820 add the annotations. wait_phase "available" therefore returns immediately at Lines 822-823. Stage7 can then pass with the original PVCs, without either repave running.
Wait for each instance to leave available, then wait for it to return to available. Also verify that each trigger value reaches that instance’s status.lastAppliedRepaveTrigger before checking PVC names.

Summary
Re-wires M1's baked-image + repave implementation (#223) onto the
Step/Runnercontroller from #230, which droppedspec.osImageand all of M1's controller-side wiring when it landed. Restores the image catalog, drift detection, and repave as a properinternal/ensurestep.Closes #252.
Design discussion: #168 (comment).
