[bug\_fix] CreateContainerConfigError: Pod cannot create the container because a referenced Secret or ConfigMap is missing

Run kubectl describe pod and read the Events. If the event mentions configmap ... not found or secret ... not found, create the missing object with kubectl create configmap or kubectl create secret, or correct the reference in env, envFrom, or volumes. Also verify that an envFrom key references an existing key name; a missing key referenced with env.valueFrom.key creates the same error.

Journey Context:
You apply a new manifest and the pod stays in CreateContainerConfigOff. kubectl describe pod shows Error: configmap app-config not found. You realize the Helm template conditionally skips the ConfigMap but the Deployment always mounts it. After creating the ConfigMap, the pod advances to a similar error for a Secret used by envFrom. You inspect the Secret and see a typo in the key name under stringData. Fixing the key name lets kubelet build the container config and the pod starts. The fix works because kubelet must resolve every env var, volume, and config reference before it can hand the container spec to the runtime; any unresolved reference blocks container creation.
