Summary

Execute every immutable v1beta2 DynamoGraphDeploymentRun as one isolated AISimulate Kubernetes Job and reflect the exact frozen input and Job lifecycle in Run status.

The Request and Run controllers keep separate ownership:

• the Request controller copies the admission-defaulted typed NativeSearchInput into an immutable Run;

• the Run controller lowers that snapshot, applies caller inputOverrides to the public AISimulate search input, and then injects operator-owned dgdr_run identity and execution values;

• a Run-owned ConfigMap freezes the final input.yaml, Planner and publisher images and pull policies, runtime-image source, normalized Dynamo version, GPUs per node, snapshot path, and image-pull secrets;

• status.aisimulate.input records the exact document mounted into the Job;

• the Job runs the standard public CLI:

  aisimulate recommend --stack dynamo \
    --config /etc/aisimulate/input.yaml \
    --output dgdr_run \
    --output-dir /var/run/aisimulate/output \
    --overwrite
  

The Job always has two containers. The operator-configured Planner image runs AISimulate, while the operator image runs the dedicated /dgdr-run-publisher executable. The publisher remains a separate command from the long-running /manager process while shipping in the same Operator image. They share only the snapshot volume; only the publisher receives projected Kubernetes credentials.

The operator and Planner image are one tested release bundle. A Request or Run cannot select a skewed Planner/AISimulate image or version. The controller derives the Planner image from the existing --dgdr-default-image setting and does not persist that deployment choice in the DGDR API.

Refs DGH-1426.

Lowering and ownership

inputOverrides is authoritative over the public recommendation input, but not over Kubernetes identity or execution wiring:

public AISimulate static underlay
  + typed DGDR fields and defaults
  + spec.aisimulate.inputOverrides
  + operator-owned dgdr_run identity/execution values
  = immutable ConfigMap input.yaml
  = status.aisimulate.input

For example, callers may tune an adapter behavior that does not escape the Run sandbox:

spec:
  aisimulate:
    inputOverrides:
      dgdr_run:
        snapshot_interval_seconds: 5

Admission rejects caller values for dgdr_run.name, namespace, snapshot_dir, runtime_image, runtime_version_override, num_gpus_per_node, max_candidates, and derive_runtime_images. The controller reinjects those fields after merge-patch lowering, so an opaque override cannot publish into another namespace, change resource identity, escape the shared volume, bypass the typed candidate cap, or select a skewed runtime.

The frozen ConfigMap is the restart boundary. Subsequent reconciliation reads that snapshot instead of deriving execution settings again from mutable Helm configuration. Cache lag is distinguished from real deletion through the uncached API reader; a genuinely missing snapshot while its Job exists is terminalized as InvalidExecution rather than reconstructed with possibly changed values.

Production CI images may use an opaque Git-SHA tag. When a sibling Planner or backend image is derived, only a shared release tag is transferred. Repository-specific OCI digests are never copied to a different repository; digest-only source references are rejected.

Follow-up: resolve the operator-configured Planner tag to a digest-pinned tag@digest reference before freezing a Run, while retaining the release tag separately for sibling Runtime-image derivation. This remains operator-owned and does not reintroduce image or version fields into the DGDR API. The broader Planner/Runtime image split is listed in #17308.

Controller behavior

• finds the Run-owned Job through a controller-owner UID index rather than its generated name;
• creates Run-owned input ConfigMap, ServiceAccount, Role, RoleBinding, and Job resources;
• pins the Planner container to numeric UID 1000, matching the image's named dynamo user so kubelet can enforce runAsNonRoot, while leaving the publisher on its own image UID;
• reuses the frozen execution snapshot after controller restarts;
• exposes the exact effective input through status.aisimulate.input;
• owns jobRef, phase, execution timestamps, and Completed, while preserving publisher-owned progress and candidate status;
• preflights the Candidate API before starting execution;
• resolves and freezes image-pull secrets for both containers;
• treats an explicitly budgeted external AISimulate SKU as authoritative while discovering node topology without filtering by that external catalog identifier;
• reacts to a newer Request generation by deleting only the execution Job, then retaining the immutable Run and Candidate history as Completed=True, reason=Superseded;
• terminalizes deterministic immutable-input, ownership, and Kubernetes-invalid failures while leaving discovery, secret resolution, cache lag, conflicts, and status-write failures retryable;
• refuses to adopt ownerless, foreign-owned, or stale same-name ServiceAccounts, Roles, RoleBindings, and ConfigMaps.

This PR depends on the v1beta2 admission, Request-controller, publisher, output-adapter, and public-input changes. The branch includes the current publisher terminal-outcome, typed-manifest, retry, and cache-observation completion contract from devivasudevan/dynamo#5, because the Run controller depends on that exact termination protocol. It also depends on #17407 for the shared sibling-image helper; that fix is intentionally owned by a separate v1beta1 profiler PR because the incorrect OCI-digest propagation predates v1beta2. This branch now follows the current #17407 contract exactly: implicit latest remains implicit, a same-repository digest is preserved, a digest is dropped when deriving a different repository, and the existing profiler import path re-exports the shared helpers. Until those prerequisites land, their commits also appear in this branch.

Priority: Normal

Estimated code review effort: 5 (Critical) | ~90 minutes

Merge Risk: Moderate · up to 2d18e

With the v1beta2 flag enabled, the operator may be unable to create the Run's publisher permissions, so Runs would not start. Separately, a Run with an input that can never execute blocks later edits to its Request until someone deletes the Run. Fix the operator RBAC and the permanent-failure handling before merging. The other findings are minor cleanups.

- Around line 24-30: Add a timeout marker to the module-level pytestmark list in
test_adapter.py, which contains sleep, polling, and writer-thread tests. Keep
pytestmark as a list and set the timeout to 60 seconds.

Review comments at @deploy/helm/charts/platform/components/operator/values.yaml:
- Around line 40-41: Update the chart description for Requests into Runs to
state that the operator includes the Run controller when dgdrV1Beta2.enabled is
true; keep the descriptions consistent across the chart values and generated
README.

Review comments at
@deploy/operator/internal/controller/dynamographdeploymentrun_v1beta2_controller.go:
- Around line 90-96: Update the RBAC markers near the
`dynamographdeploymentruns` permissions to grant the candidate permissions
required by `reconcilePublisherAccess`: add access to
`dynamographdeploymentcandidates` and its `status` subresource with the
requested verbs, then regenerate the operator Role.
- Around line 109-111: Handle permanent Invalid errors from Job creation
separately from transient errors in the controller’s Job creation path. Mark the
Run as Phase=Failed and Completed=True with reason InvalidInput, then return
without retrying; if writing the status fails, return that error. Preserve the
existing retry behavior for other Job creation errors.

Review comments at @deploy/operator/internal/dgdrrunpublisher/reconciler.go:
- Around line 161-166: Update the final-pass flow around `Completion.Finish` so
candidate state comes from the live API reader, not the informer cache, before
finishing. Identify final passes using `desired.Terminal || exited` and pass
that context into `apply`; use the API reader already wired into
`clientWriter.Reader` to list candidates on those passes, preserving cached
reads for non-final passes.

Review comments at @deploy/operator/internal/dgdrrunpublisher/snapshot.go:
- Around line 99-104: Update validateManifest to use decodeManifest with a
DesiredCandidate containing the candidate ID and manifest spec, so typed
decoding errors are returned as protocol violations during snapshot parsing.

Review comments at @deploy/operator/internal/gpu/dcgm_phase_context_test.go:
- Line 1: Add the repository-standard SPDX and full Apache license header to the
test file before the package declaration, matching the header format and
copyright range used by neighboring Go files such as
hardware_discoverer_test.go.

Review comments at
@deploy/operator/internal/webhook/validation/dynamographdeploymentrequest_carrier_envtest_test.go:

Review comments at
@docs/fern/pages/reference/kubernetes-api/additional-resources/api-reference-k8s.md:
- Line 3441: Update the API documentation source or generator inputs for
WorkloadSpec, mode, and static so the generated reference describes explicit
empty-workload defaults as admission-applied and omits the removed schema
defaults for mode and static; regenerate the API reference and
full-api-reference.mdx rather than editing generated output directly.

Review comments at
@docs/fern/pages/reference/kubernetes-api/full-api-reference.mdx:
- Line 4809: Update the API documentation generation flow so the descriptions of
an empty workload and workload.static match the Go types and CRDs: describe the
shape as supplied by admission, and remove the claim that the API schema applies
a default to static. Regenerate the affected documentation through its owning
generator rather than changing the generated page directly.
