instruction: Create a Kubernetes Service configuration with best practices
output: ```yaml
  apiVersion: v1
  kind: Service
  metadata:
   name: my-nginx
   labels:
   run: my-nginx
  spec:
   ports:
   - port: 80
   protocol: TCP
   selector:
   run: my-nginx

  # Create a kustomization.yaml composing them
  cat <<EOF >./kustomization.yaml
  resources:
  - deployment.yaml
  - service.yaml

  The resources from kubectl kustomize ./ contain both the Deployment and the Service objects.CustomizingPatches can be used to apply different customizations to resources. Kustomize supports different patching
  mechanisms through StrategicMerge and Json6902 using the patches field. patches may be a file or
  an inline string, targeting a single or multiple resources.The patches field contains a list of patches applied in the order they are specified. The patch target
  selects resources by group, version, kind, name, namespace, labelSelector and annotationSelector.Small patches that do one thing are recommended. For example, create one patch for increasing the deployment
  replica number and another patch for setting the memory limit. The target resource is matched using group, version,
  kind, and name fields from the patch file.# Create a deployment.yaml file
  cat <<EOF > deployment.yaml
