[bug\_fix] CreateContainerConfigError

Run \`kubectl describe pod\` and read the Events line from the kubelet. It will name the missing ConfigMap, Secret, or downwardAPI field. Create the missing object, correct the referenced name, or mount the optional field as \`optional: true\` if absence is acceptable. Once the referenced object exists and the name matches, the kubelet can create the container.

Journey Context:
A new Pod stayed stuck in \`CreateContainerConfigError\` immediately after creation. The container never started, so there were no logs. \`kubectl describe pod\` showed an Event: \`Error: configmap "app-config" not found\`. The developer had renamed the ConfigMap in \`kustomization.yaml\` but forgot to update the \`envFrom.configMapRef.name\` in the Deployment. After creating the correctly named ConfigMap \(and later fixing the Deployment reference\), the Pod moved to \`ContainerCreating\` and then Running.
