Summary

Breaking. oci:// now names a CNCF ModelPack artifact in a container registry, acquired through a running llmman serve daemon. Oracle Cloud Object Storage moves to ocios://.

# CNCF ModelPack artifact (new meaning of oci://)
storageUri: oci://ghcr.io/org/model:tag

# Oracle Object Storage (moved, format otherwise identical)
storageUri: ocios://n/mynamespace/b/mybucket/o/models/llama

Model distribution is increasingly moving to OCI registries -- the same registries, credentials, mirroring and air-gap tooling a cluster already uses for container images. Taking oci:// for that, rather than inventing a second scheme, keeps the URI meaning what it means everywhere else in the ecosystem.

Migration

Before After
oci://n/ns/b/bucket/o/path ocios://n/ns/b/bucket/o/path

Nothing is removed. The entire Object Storage path keeps working unchanged under the new scheme, via a new StorageTypeOCIObjectStore:

  • pkg/ociobjectstore — untouched
  • HFToOCIReplicator, OCIToOCIReplicator, PVCToOCIReplicator — untouched, still upload to Object Storage
  • benchmark storage args, the fine-tuned adapter injector, the gopher task queue and model deletion — all repointed at the new type

Parsing an old oci://n/... URI fails with a message that names the replacement rather than a generic format error, so the migration is self-describing:

"oci://n/ns/b/bucket/o/path" looks like an Oracle Object Storage URI, which oci:// no longer
addresses; oci:// now names a CNCF ModelPack artifact (oci://{registry}/{repository}:{tag})

Implementation

  • pkg/utils/storage: oci:// → ModelPack reference; ocios:// + StorageTypeOCIObjectStore carry the Oracle format and parser verbatim.
  • pkg/llmman (new): the daemon client, standard library only, no new dependency. GET /api/version probes reachability and identity (a server without a version field is reported as "not an llmman daemon", distinct from nothing listening). POST /api/pull streams NDJSON; an error arriving in-band at HTTP 200, or a stream ending without success, are both failures rather than a completed pull. llmman resolve --no-pull then reports the on-disk path -- --no-pull keeps the daemon the only thing that touches the network. LLMMAN_HOST is parsed as llmman's own clients do, including rewriting a wildcard bind (0.0.0.0, [::]) to loopback.
  • pkg/modelagent: StorageTypeOCI routes to processModelPackModel; deletion and local-artifact checks cover both schemes. Files are hard-linked out of llmman's store where possible, falling back to a copy across filesystems, so a shared model costs its bytes once.

A pull needs both the daemon reachable and the binary on PATH (or OME_LLMMAN_BIN); each missing piece has its own actionable error, and neither is required unless an oci:// URI is used.

Testing

$ go test ./pkg/... ./internal/...
93 ok, 12 FAIL

Baseline on a clean tree, same environment: 92 ok, 12 FAIL. The +1 is the new pkg/llmman, and the failure set is byte-identical to baseline (verified by diffing the two lists -- only elapsed times differ). All 12 are pre-existing: seven are -lxet link failures from the unbuilt Rust static lib (basemodel, pernode, modelagent, xet, model-metadata, replica, replica/common, replica/replicator), plus inferenceservice and webhook/admission/pod which already fail on main.

New pkg/llmman/client_test.go (13 tests) runs against a real httptest server, so the NDJSON contract is genuinely exercised: version probe accepted / non-llmman rejected / nothing-listening actionable; pull success with forwarded byte progress and the request body asserted; in-band error at HTTP 200; stream ending without success; non-OK status; non-JSON diagnostic tolerated; the resolve contract plus six malformed cases; binary default/override/empty-override; missing-binary error.

New pkg/utils/storage/storage_modelpack_test.go pins both schemes: a ModelPack reference parsed whole (including a registry port and a digest); bad input rejected; the migration hint asserted explicitly; Object Storage still parsing under ocios://; GetStorageType distinguishing the two; and ValidateStorageURI accepting both while rejecting an Oracle URI under oci://.

Existing fixtures across storage, benchmark, benchmark/utils and the benchmark webhook were migrated to ocios://, and docs under site/content/en/docs/ updated with the breaking-change note.

  • gofmt -l pkg/ internal/ clean; go vet reports only the three pre-existing pkg/xet unsafe.Pointer warnings

Not verified here, flagged rather than implied: no live cluster run, and no pull against a real registry through a live llmman serve. pkg/modelagent cannot be test-linked in this environment (-lxet), so processModelPackModel is covered by inspection rather than execution.

Disclosure: written with AI assistance.

Summary by CodeRabbit

  • New Features

    • Added support for downloading and materializing CNCF ModelPack OCI artifacts through the llmman service.
    • Added progress reporting and improved handling for artifact download failures.
    • Added support for both OCI artifacts (oci://) and Oracle Cloud Object Storage (ocios://).
  • Breaking Changes

    • Oracle Cloud Object Storage URIs must now use the ocios:// scheme. Existing oci://n/... URIs are no longer accepted.
  • Documentation

    • Updated configuration examples and reference documentation with the new URI formats.

BREAKING CHANGE: oci:// no longer addresses Oracle Cloud Object Storage.

oci:// now names a CNCF ModelPack artifact in a container registry
(oci://{registry}/{repository}:{tag}), acquired through a running
`llmman serve` daemon. Oracle Cloud Object Storage moves to ocios://,
with an otherwise identical format:

    oci://n/ns/b/bucket/o/path   ->   ocios://n/ns/b/bucket/o/path

Model distribution is increasingly moving to OCI registries, which lets
a cluster reuse the registry, credentials, mirroring and air-gap tooling
it already has for container images. Taking oci:// for that, rather than
inventing a second scheme, keeps the URI meaning what it means everywhere
else in the ecosystem.

Nothing is removed: the whole Object Storage path -- pkg/ociobjectstore,
the HFToOCI/OCIToOCI/PVCToOCI replicators, benchmark args and the
fine-tuned adapter injector -- keeps working unchanged under the new
scheme, via StorageTypeOCIObjectStore. Parsing an old oci://n/... URI
fails with a message naming the replacement rather than a generic format
error, so the migration is self-describing.

Acquisition is delegated to llmman, which already implements the
ModelPack media types, registry auth, resumable blob download and a
content-addressed store. The daemon does the pull (POST /api/pull,
streamed as NDJSON so a multi-gigabyte fetch is not silent, and an error
arriving in-band at HTTP 200 is caught) but deliberately exposes no local
path, so `llmman resolve --no-pull` reports where the bytes landed. The
client uses only the standard library, so no new dependency.

Files are hard-linked out of llmman's store where possible, falling back
to a copy across filesystems, so a model shared with it costs its bytes
once rather than twice.

Review Change Stack

📝 Walkthrough

Walkthrough

The change reserves oci:// for CNCF ModelPack artifacts and moves Oracle Cloud Object Storage to ocios://. It adds llmman-based artifact retrieval and materialization, updates runtime routing and parsing, refreshes tests, and revises documentation examples.

Changes

OCI model and object-storage split

Layer / File(s) Summary
Storage URI contract
pkg/utils/storage/storage.go, pkg/utils/storage/*_test.go
oci:// now parses ModelPack references. ocios:// parses Oracle Cloud Object Storage references. Type detection, validation, object URI creation, and migration errors follow the split.
llmman ModelPack download flow
pkg/llmman/*, pkg/modelagent/gopher_modelpack.go
The new client checks the daemon, streams pull progress, resolves artifact paths, and materializes files or directories.
Runtime storage routing
pkg/modelagent/gopher.go, pkg/modelagent/gopher_task_queue.go, internal/ome-agent/replica/*, pkg/controller/v1beta1/benchmark/*, pkg/webhook/admission/*
ModelPack and Oracle Object Storage types use separate download, queue, replica, benchmark, and fine-tuned-weight paths.
URI documentation updates
site/content/en/docs/**
Examples and supported formats use ocios:// for Oracle Cloud Object Storage and document the oci:// ModelPack behavior.

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

Merge Risk: 🟠 High · up to 97b4d

This change adds ModelPack-based model acquisition and renames Oracle Object Storage URIs, but the current implementation can exhaust memory while copying large models, report models ready without required configuration metadata, or fail at runtime when Object Storage dependencies are missing. These correctness and availability risks should be fixed before merging.

🌐 Web query:

Go os.ReadFile documentation: Does os.ReadFile read the entire file into memory?

💡 Result:

Yes, the os.ReadFile function in Go reads the entire contents of a file into memory [1][2]. When you call os.ReadFile, the function opens the specified file and allocates a backing array in heap memory large enough to hold the entire file's data [2][3]. It then performs one or more read operations to copy the file's contents into this memory buffer before returning it as a []byte slice [2][4][5]. Because this process loads the entire file into memory at once, it is suitable for smaller files but can lead to high memory usage or out-of-memory errors if used on very large files. For handling large files, it is generally recommended to use other approaches, such as reading the file in smaller chunks using a bufio.Reader or by calling the Read method on an *os.File object iteratively.

Stream the cross-filesystem copy.

When os.Link fails across filesystems, os.ReadFile loads the complete payload into memory. A multi-gigabyte payload can exhaust agent memory and fail materialization. Use io.Copy with open source and destination files. Add a regression test for the fallback path.

Register ModelPack configuration before marking the model ready.

processModelPackModel only pulls and materializes the artifact. The ModelPack branch then reaches safeNodeLabelReconciliation and records Ready without registering model configuration metadata.

Add safeParseAndUpdateModelConfig after materialization. Add a regression test for the ConfigMap update.

Reject empty Object Storage namespace and bucket values.

ParseOCIObjectStoreURI accepts invalid forms such as ocios://n//b/my-bucket/o/results and ocios://n/ns/b//o/path because it does not require the namespace and bucket components to be non-empty. Require parts[1] and parts[3] to be non-empty, and add regression coverage using the actual empty-namespace form.

Rename the provider to OCI Object Storage.

The table labels the ocios:// scheme as OCI, while this change reserves oci:// for ModelPack artifacts. Use the full provider name to prevent users from selecting the wrong URI scheme.

Suggested documentation update
-| OCI | `ocios://n/{namespace}/b/{bucket}/o/{path}` | `ocios://n/myns/b/mybucket/o/results` |
+| OCI Object Storage | `ocios://n/{namespace}/b/{bucket}/o/{path}` | `ocios://n/myns/b/mybucket/o/results` |

URI schemes table entry for the `ocios://` provider to label it `OCI Object
Storage` instead of `OCI`, while leaving the scheme and example unchanged.

Supported formats:</p>

Add the ModelPack URI to the supported formats.

StorageSpec now supports oci:// for CNCF ModelPack artifacts, but this list documents only ocios:// for OCI Object Storage. Add the ModelPack format so the API reference exposes both schemes.

Suggested documentation update
 <li>OCI Object Storage:   ocios://n/{namespace}/b/{bucket}/o/{object_path}</li>
+<li>CNCF ModelPack:       oci://{registry}/{repository}[:{tag}]</li>
