Report #756

[bug\_fix] 0/3 nodes are available: insufficient cpu \(or memory\)

Scale the cluster \(add nodes\), reduce replica count, lower per-pod CPU/memory requests/limits, or remove pods' node affinity/taints that unnecessarily restrict scheduling. Use \`kubectl describe pod\` to see the scheduler's exact predicate failure and \`kubectl top node\` to confirm resource pressure.

Journey Context:
A Deployment with 10 replicas stays Pending. \`kubectl describe pod\` shows \`0/3 nodes are available: 1 Insufficient cpu, 2 Insufficient memory\`. The scheduler cannot place the pod because the sum of existing requests plus this pod's request exceeds node capacity. The manifest set \`requests.cpu: 2\` when the app only uses 200m. Lowering the request to a realistic value lets pods schedule. Alternatively the cluster genuinely needs more nodes; after scaling the node group, Pending pods schedule.

environment: Kubernetes cluster with fixed-size or autoscaled node pool, multiple workloads competing for CPU/memory, Deployment with resource requests · tags: pending scheduling insufficient cpu memory node affinity taint resources · source: swarm · provenance: https://kubernetes.io/docs/concepts/scheduling-eviction/scheduling-framework/
