- Line 48: Update the deployment security context for the pod mounting /app/data
so its non-root runtime user can write to the fresh job-queue-pvc volume;
configure an appropriate fsGroup or equivalent OpenShift ownership mechanism
while preserving runAsNonRoot and the existing ssh-keygen startup flow.
- Around line 47-50: Update the SSH key initialization block before uvicorn
starts to validate the private key, derive its public key from that validated
key, and atomically replace /app/data/nebius-ssh-key.pub. Ensure startup fails
for a missing or corrupt private key and never proceeds with a stale or missing
public key; preserve the existing failure behavior for unsuccessful key
operations.

Validate the complete SSH key pair.
If /app/data/nebius-ssh-key exists but its .pub file is missing, the startup check succeeds. With NEBIUS_ENABLED=1, NebiusInstanceManager then fails while reading the missing public-key file. A stale or mismatched public key can register a different key from the one later used for SSH.
Derive the public key from the validated private key and atomically replace the .pub file before starting uvicorn. This also rejects a corrupt private key before the service starts.

Ensure the fresh PVC is writable by the pod’s non-root user.
job-queue-pvc uses the gp3 storage class and mounts at /app/data. The pod defines runAsNonRoot but no fsGroup or explicit runAsUser. If the provisioned filesystem is root-owned without write permission for the runtime UID, ssh-keygen fails and the container exits before the service starts. Provide an ownership or permission mechanism through the OpenShift deployment, or restore an appropriate fsGroup.
