我是kustomize的新手，正试图弄清楚如何修补我通过OpenShift容器平台运行的入口。
基本配置工作正常，覆盖工作，直到我介绍了我的入口覆盖补丁。作为参考，补丁服务覆盖确实工作，所以我很确定我的结构和链接都很好，但是当同步到OpenShift（通过ArgoCD）时，我在项目上得到的错误是：

我认为我的路径可能是错误的，但是我似乎无法找出如何正确识别规范的替换路径，当它是defaultBackend。我尝试了/spec/defaultBackend/0/service/port和/spec/0/defaultBackend/service/port的路径，如果它是一个数组。

错误告诉你你需要知道的一切：

cannot unmarshal number into Go struct field

首先，看看初始Ingress清单的格式：

kind: Ingress
apiVersion: networking.k8s.io/v1
metadata:
  name: mssql-example-adc
  annotations:
    ingress.citrix.com/frontend-ip: 192.168.1.10
    ingress.citrix.com/insecure-port: '1433'
    ingress.citrix.com/insecure-service-type: tcp
    kubernetes.io/ingress.class: citrix-vpx
spec:
  defaultBackend:
    service:
      name: mssql-service
      port:
        number: 31433

型
特别注意spec.defaultBackend.service.port的结构。
现在，看看补丁生成的输出：

$ kustomize build
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    ingress.citrix.com/frontend-ip: 192.168.1.10
    ingress.citrix.com/insecure-port: "1433"
    ingress.citrix.com/insecure-service-type: tcp
    kubernetes.io/ingress.class: citrix-vpx
  name: mssql-example-ingress-dev
spec:
  defaultBackend:
    service:
      name: mssql-service
      port: 31434

型
你看出区别了吗？您替换了一个结构化值：

port:
  number: 31433

型
使用整数：

port: 31434

型
只需将您的补丁更新为目标...service/port/number即可：

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
- ingress.yaml

patches:
  - target:
      name: mssql-example-adc
    patch: |
      - op: replace
        path: /metadata/name
        value: mssql-example-ingress-dev
      - op: replace
        path: /spec/defaultBackend/service/port/number
        value: 31434

型
其结果是：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    ingress.citrix.com/frontend-ip: 192.168.1.10
    ingress.citrix.com/insecure-port: "1433"
    ingress.citrix.com/insecure-service-type: tcp
    kubernetes.io/ingress.class: citrix-vpx
  name: mssql-example-ingress-dev
spec:
  defaultBackend:
    service:
      name: mssql-service
      port:
        number: 31434
