Merge Risk: 🟡 Moderate · up to 8c61c

Two Pods that start at the same time with the same private-registry credentials can cause one of them to fail permanently. Some image errors can also be treated as capacity shortages, which temporarily excludes healthy RunPod placements. Fix both before merging.

Security Architecture Review

Security architecture risk: 🟠 High · up to 8c61c

RunPod workloads with declared ports can receive an unauthenticated public endpoint, and private-registry credentials are copied into persistent RunPod account objects. Provisioning recovery also has unresolved ownership and concurrency risks.

Retained concerns

  • High · security · observed: Declared workload ports are exposed through a RunPod proxy documented as unauthenticated, while the provider returns no connection token. Applications relying on the provider to restrict inbound access would cross a new public-access boundary.
  • Medium · security · observed: Private-registry username and password are stored as reusable RunPod account objects. The added Pod teardown path does not delete those objects, leaving credential revocation and ownership after workload removal outside this lifecycle.
  • Medium · reliability · inferred: Claim lookup and creation are not atomic, and lookup can reuse a terminated Pod as reserved capacity. Concurrent or interrupted provisioning may therefore leave claim ownership or cleanup ambiguous; whether RunPod enforces unique names and immediate list visibility remains unproven.
Security review details

Security Blast Radius

  • inferred — The new inbound exposure applies to RunPod workloads with exposed ports; the credential-storage exposure applies to private-image workloads using basic auth. The source does not establish RunPod-side account isolation or ingress ACLs.

Security Findings and Attack Paths

  • inferred — An external party able to reach a declared RunPod HTTP port encounters no provider-issued proxy token; any required application authentication must be supplied by the workload. No application-level authentication bypass was verified.

Trust Boundaries and Controls

  • observed — The control plane supplies resolved, potentially secret-bearing environment values and registry credentials to the external provider. The adapter validates basic auth, rejects unsupported auth and restrictive egress, and redacts PodSpec environment values when formatted.

Resilience and Maintainability Implications

  • inferred — Idempotent deletion and name-based retry recovery limit some partial failures, but a concurrent claim race or reuse of a terminated Pod can undermine ownership and cleanup assumptions for workloads carrying secrets.

Hardening Proposals

  • proposed — Make public ingress an explicit workload contract, with authentication at the application or ingress boundary where required; define deletion and rotation ownership for RunPod registry-auth objects.
  • proposed — Establish RunPod name-uniqueness and list-consistency guarantees, then make concurrent creation and terminal-state recovery explicit in the claim lifecycle.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Classify image-pull failures before capacity failures, or narrow the capacity patterns.

The capacity case runs before the image-pull case. It matches the generic substrings "not available" and "unavailable". A create rejection such as "image not available" or "manifest unavailable" therefore gets wrapped with provider.ErrNoCapacity, not provider.ErrImagePull. ClassifyProvisionError then installs a block for that accelerator, tier, and region. One Pod's bad image then excludes a healthy candidate for every other Pod until the TTL expires. The comment on Lines 257-259 names exactly this failure as the thing to prevent.

Move the registry/image case above the capacity case. Alternatively, drop the bare "not available" and "unavailable" patterns and keep only the specific capacity phrases.

🌐 Web query:

Does RunPod REST API POST /containerregistryauth reject a duplicate name?

💡 Result:

Yes. RunPod’s API documentation says the `name` must be unique, so creating another registry auth with an existing name should be rejected. The docs I found don’t specify the exact HTTP status code or error body. [1]

Handle concurrent EnsureRegistryAuth calls.

EnsureRegistryAuth lists and then creates without synchronization. If two Provision calls for the same credentials overlap, both can miss the matching object. RunPod requires unique names, so one create can fail. The error reaches vnode as ProvisionFailed, and vnode stores the failed state without retrying.

Re-list after a failed create and reuse the matching object:

🐛 Proposed fix
 	var created registryAuthResponse
 	if err := c.do(ctx, http.MethodPost, registryAuthPath, body, &created); err != nil {
+		// A concurrent Provision may have created the same content-addressed object.
+		var again []registryAuthResponse
+		if lerr := c.do(ctx, http.MethodGet, registryAuthPath, nil, &again); lerr == nil {
+			for _, e := range again {

+					return e.ID, nil
