[bug\_fix] CreateContainerConfigError: referenced ConfigMap or Secret key does not exist

Run \`kubectl describe pod\` to see which ConfigMap, Secret, or projected volume key is missing. Create the missing object or key, or correct the envFrom/env/valueFrom reference in the manifest so it points to an existing key. If the pod uses \`subPath\`, also verify the referenced path exists in the volume.

Journey Context:
I applied a Deployment that mounted a TLS secret and injected a database URL from a ConfigMap. The pod hung in \`CreateContainerConfigError\`. \`kubectl describe pod\` showed \`Error: secret "api-tls" not found\` and then, after I created that secret, a second event: \`Error: configmap "app-config" not found\`. The environment had been deployed from a Helm chart that conditionally created the ConfigMap, but a values override disabled it. I created the ConfigMap with the expected keys \(\`DB\_URL\`, \`LOG\_LEVEL\`\), and the pod moved to Running. The root cause was a stale reference in the Deployment spec pointing to objects that were not guaranteed to exist in that environment.

environment: Kubernetes 1.27 bare-metal cluster, workloads deployed with Helm 3, cert-manager for TLS secrets, namespace-scoped ConfigMaps. · tags: createcontainerconfigerror configmap secret envfrom valuefrom missing-key · source: swarm · provenance: https://kubernetes.io/docs/tasks/configure-pod-container/configure-pod-configmap/
