os.cpu_count() Gets Wrong in a CPU-Limited Kubernetes PodA hands-on Minikube lab showing why `os.cpu_count()` returns the node's full CPU count inside a CPU-limited pod, and what happens when Gunicorn sizes workers from that number instead of the cgroup quota.
What actually happens when you request nvidia.com/gpu: 1? A step-by-step trace through the scheduler, kubelet device manager, gRPC allocation on nvidia-gpu.sock, and container injection, on a real minikube cluster with an RTX 3050.
