📝 WalkthroughWalkthroughThe pull request adds managed workload identity for deployments. It captures authentication context, creates Docker and Kubernetes workload delegations, propagates identity through deployment backends, configures Authentik runtimes, and adds unit, integration, and end-to-end coverage.

Suggested reviewers: Merge Risk: 🟠 High · up to This PR adds creator-delegated workload credentials to Docker and Kubernetes deployments, but the current head can expose a gateway TLS private key to workloads and attach a creator’s authorization context to the wrong Kubernetes pod or resource; it also has paths that break custom-audience exchange, leave Docker delegations unreconciled, or start OpenShell workloads without credentials. These high-impact security and correctness issues make the PR not merge-ready until addressed. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@contrib/auth/authentik/config/platform-compose-authentik.yaml`:
- Around line 86-89: Remove the gateway TLS volume mount from the workload
configuration at contrib/auth/authentik/config/platform-compose-authentik.yaml
lines 86-89, and update the corresponding workload configuration at
tests/auth_idp/authentik_live.py lines 220-225 to mount only the CA certificate,
never tls.key; keep gateway-tls-init’s certificate and key volume unchanged.
In
`@plugins/nemo-deployments/src/nemo_deployments_plugin/backends/docker/backend.py`:
- Around line 678-682: Update the config-present branch of the workload identity
revocation method used by _sync_workload_identity_for_status to wrap
revoke_by_workload in best-effort exception handling, matching
_cleanup_missing_workload_identity, so cleanup errors do not escape read_status
or _observe_one_shot_primary_after_create. Preserve the existing terminal
BackendStatusUpdate flow, while leaving delete_deployment’s explicit
cleanup-failure reporting unchanged.
- Around line 660-666: Update the config-unavailable deletion path around
_workload_delegations.revoke_by_workload to use the resolved workload kind and
workload ID from provisioning rather than DEFAULT_WORKLOAD_KIND and name.
Persist that resolved identity for deletion, or alternatively revoke the
delegation names recorded during provisioning.
- Line 134: Update DOCKER_WORKLOAD_TOKEN_WRITER_IMAGE to reference busybox by an
immutable digest instead of the implicit latest tag; if DockerExecutorConfig
supports air-gapped registry overrides, route this image reference through that
configuration while preserving the existing token-writer behavior.
In
`@plugins/nemo-deployments/src/nemo_deployments_plugin/backends/k8s/deployments.py`:
- Around line 430-445: In create_deployment and create_job, after a 409
collision, validate the returned resource’s identity labels and return FAILED
immediately when they do not match the requested resource. Ensure this guard
runs before _read_pods and reconcile_pod_uid_delegations in
deployments.py:430-445 and jobs.py:332-347, preventing pod delegation for
foreign resources.
In
`@plugins/nemo-deployments/src/nemo_deployments_plugin/backends/k8s/workload_identity.py`:
- Line 207: Update the ReplicaSet ownership resolution around the
controller_name_prefix check to require an exact owning Deployment match, not
merely an owner name sharing the target prefix. Exclude ReplicaSets such as
target-extra, and bind the target Deployment’s auth_context only after the exact
ownership is confirmed.
In
`@plugins/nemo-deployments/src/nemo_deployments_plugin/backends/openshell/backend.py`:
- Line 299: Update the OpenShell backend entry point around the auth_context
parameter to reject configurations with workload_identity.enabled before
creating the sandbox, returning a clear failed status; do not accept or proceed
with auth_context until delegation and token-file provisioning is implemented.
In `@plugins/nemo-deployments/src/nemo_deployments_plugin/entities.py`:
- Line 171: Update the Docker delegation creation flow to use
WorkloadIdentitySpec.token_audience, including threading the configured value
through every backend delegation builder and into the platform audience helper.
Preserve the default audience behavior when token_audience is unset;
alternatively remove the unsupported tokenAudience field and its exposed model
alias.
Apply the same fix in
`@plugins/nemo-deployments/src/nemo_deployments_plugin/backends/k8s/workload_identity.py`
at line 93: The Kubernetes delegation record uses the default audience instead
of the configured projected-token audience.

Do not mount the gateway TLS volume into workloads. gateway-tls-init copies both tls.crt and tls.key into this volume. A workload can read tls.key even when the mount is read-only. Mount only the CA certificate in both workload configurations.

Revoke delegations using the resolved workload identity.
The fallback uses DEFAULT_WORKLOAD_KIND and name, but provisioning can use overridden workloadKind and workloadId. When the deployment config is unavailable during deletion, those delegations are not revoked. Persist the resolved identity or revoke delegation names recorded during provisioning.

Make the config-present revocation best-effort.
The config is None branch catches exceptions, but this branch does not. _sync_workload_identity_for_status (line 726) calls this method from read_status after the outer try/except block has ended, and from _observe_one_shot_primary_after_create. An entity-store or network error during revoke_by_workload then propagates out of read_status instead of returning the terminal BackendStatusUpdate that was already computed at line 1207. GPU release has already happened at that point, so the status is lost and the reconciler must re-derive it.
_cleanup_missing_workload_identity already wraps the same calls in try/except, which shows the intended best-effort contract.

Authorization Bypass (CWE-862): Missing Authorization
Block delegation reconciliation after a foreign-resource collision.
When a 409 returns a resource with mismatched identity labels, return FAILED before listing or reconciling its pods in both create_deployment and create_job. Otherwise, a colliding resource's owned pod can pass the owner and service-account filters and receive a delegation using the request auth_context.

Reject unsupported workload identity in OpenShell.
When workload_identity.enabled is set, this backend accepts auth_context but does not validate activation or provision a delegation and token file. It still creates the sandbox. The workload then has no exchange credential. Return a clear failed status until OpenShell supports workload identity, or implement the provisioning flow.

Honor tokenAudience consistently across deployment backends. The configured audience is projected into Kubernetes workload tokens, but delegation records use a separate default; Docker delegation creation also uses the platform default. Custom-audience workloads therefore fail token exchange. Thread the resolved audience through both delegation builders, or remove the unsupported field, and add non-default-audience coverage.

TL;DR
Adds workload identity token exchange support for deployment workloads so Docker and Kubernetes deployments can exchange injected subject tokens for delegated platform access using the creating principal's auth context.
What Changed
Deployment creation now snapshots the caller auth context and carries it into the deployment reconciler and backend execution path.
DeploymentConfigaccepts aworkloadIdentityspec, reservesNMP_WORKLOAD_IDENTITY_TOKEN_FILEfor platform-managed injection, and supports the camelCase request fields used by external API clients.The workload delegation helpers now live in the plugin-safe auth package with
nmp.common.authcompatibility re-exports, so jobs, deployments, agent deployments, and model deployments share the same Docker opaque-proof and Kubernetes Pod UID-bound delegation logic.Docker deployments provision per-container workload identity volumes, write opaque proof tokens for init, main, and sidecar containers, refresh live delegations, and revoke or clean up token material when containers finish, disappear, or are deleted. Kubernetes deployments and deployment-backed jobs mount projected service-account tokens, reconcile Pod UID-bound delegation rows for live pods, and revoke stale or deleted workload delegations.
Agent container deployments and model deployments opt into the new workload identity path when auth context and workload token exchange are available, allowing deployed workloads to use direct Platform SDK calls without inheriting broad service-principal reach. When
workloadIdentityis requested but token exchange or creator auth context is unavailable, the backends report a failed activation instead of silently starting an undelegated workload.Authentik Runtime Coverage
The Authentik compose and Helm demo configuration now runs the deployments service/controller and advertises deployment workload identity capabilities. The runtime contract suite adds a managed OBO deployment case and shares the workload workspace verification command used by the existing job tests.
