Report #440

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

Scale the cluster, add a node pool with larger instances, reduce the pod's \`resources.requests\` to a value justified by real usage, or remove unnecessary resource requests from best-effort workloads. Do not lower limits below requirements; adjust requests and ensure total scheduled requests fit node allocatable capacity, accounting for DaemonSet overhead.

Journey Context:
You scale a deployment from 2 to 5 replicas and the new pods sit \`Pending\`. \`kubectl describe pod\` reports \`0/3 nodes are available: 3 Insufficient cpu\`. You \`kubectl describe node\` each node and see allocatable CPU is already consumed by existing pods plus DaemonSets. The requested CPU per replica was set to \`1\` based on peak load, but average usage is only \`100m\`. You lower the request to \`250m\` and add an HPA for peaks; the scheduler places the pods. Longer term, you add a larger node pool so the cluster can absorb bursts without overcommitting.
