However, for mapstringstring, the entire list associated with a specific field gets overridden. Let's understand this better with an example, particularly on fields like featureGates and staticPodURLHeader\n\nMain kubelet configuration file contents\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: kubelet.config.k8s.io/v1beta1\nkind: KubeletConfiguration\nport: 20250\nserializeImagePulls: false\nfeatureGates:\n  AllAlpha: false\n  MemoryQoS: true\nstaticPodURLHeader:\n  kubelet-api-support:\n  - \"Authorization: 234APSDFA\"\n  - \"X-Custom-Header: 123\"\n  custom-static-pod:\n  - \"Authorization: 223EWRWER\"\n  - \"X-Custom-Header: 456\"\n```\n\nContents of a file in --config-dir directory\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: kubelet.config.k8s.io/v1beta1\nkind: KubeletConfiguration\nfeatureGates:\n  MemoryQoS: false\n  KubeletTracing: true\n  DynamicResourceAllocation: true\nstaticPodURLHeader:\n  custom-static-pod:\n  - \"Authorization: 223EWRWER\"\n  - \"X-Custom-Header: 345\"\n```\n\nThe resulting configuration will be as follows\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: kubelet.config.k8s.io/v1beta1\nkind: KubeletConfiguration\nport: 20250\nserializeImagePulls: false\nfeatureGates:\n  AllAlpha: false\n  MemoryQoS: false\n  KubeletTracing: true\n  DynamicResourceAllocation: true\nstaticPodURLHeader:\n  kubelet-api-support:\n  - \"Authorization: 234APSDFA\"\n  - \"X-Custom-Header: 123\"\n  custom-static-pod:\n  - \"Authorization: 223EWRWER\"\n  - \"X-Custom-Header: 345\"\n```\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
