您正在尝试修改/spec/ports/port，但Kubernetes服务中没有这样的路径。回想一下，一个服务看起来像这样：

apiVersion: v1
kind: Service
metadata:
  name: my-service
spec:
  selector:
    app.kubernetes.io/name: MyApp
  ports:
    - protocol: TCP
      port: 80
      targetPort: 9376

路径/spec/ports是list，不是dictionary。您可以修补/spec/ports/0/port：

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

resources:
- service.yaml

patches:
  - target:
      kind: Service
      name: my-service
    patch: |
      - op: replace
        path: /spec/ports/0/port
        value: 8080

这将导致：

apiVersion: v1
kind: Service
metadata:
  name: my-service
spec:
  ports:
  - port: 8080
    protocol: TCP
    targetPort: 9376
  selector:
    app.kubernetes.io/name: MyApp
