[bug\_fix] FailedScheduling

Run kubectl describe pod and read the FailedScheduling event. If the message says insufficient cpu or insufficient memory, reduce the pod's resource requests, delete unneeded pods, add nodes, or enable cluster-autoscaler. If the message mentions taints or affinity, add matching tolerations or nodeAffinity rules. Check kubectl describe nodes to see remaining allocatable capacity.

Journey Context:
A new pod stays Pending. The scheduler event says 0/3 nodes available: 1 Insufficient cpu, 2 Insufficient memory. Describing nodes shows all CPU allocated. Lowering the pod's CPU request from 1000m to 500m lets it fit on a node and schedule immediately because the scheduler's PodFitsResources predicate now passes.
