[bug\_fix] CreateContainerConfigError: referenced ConfigMap or Secret is missing

Run \`kubectl describe pod \` to find which ConfigMap or Secret is referenced but not found. Create the missing object with the expected name and keys, or correct the pod manifest reference. Then delete the pod so kubelet recreates it.

Journey Context:
A pod showed \`CreateContainerConfigError\`. \`kubectl describe pod\` had an event: \`Error: configmap "app-config" not found\`. The Deployment mounted a ConfigMap named \`app-config\` that I had forgotten to deploy. I applied the ConfigMap manifest with the required \`settings.json\` key, then deleted the stuck pod. The kubelet recreated the container successfully because it could now build the container configuration. The same symptom happens for Secrets used as environment variables or volumes.

environment: Kubernetes v1.30, kind cluster, ConfigMap mounted as a volume · tags: createcontainerconfigerror configmap secret missing reference container config · source: swarm · provenance: https://kubernetes.io/docs/tasks/configure-pod-container/configure-pod-configmap/
