我有一个 GKE/GCE 入口文件，它有 2 个主机。

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: my-ingress
spec:
  rules:
  - host: myfirstdomain # <-------- override this via kustomize
    http:
      paths:
      - path: /abc
        backend:
          serviceName: abc
          servicePort: abc
      - path: /def
        backend:
          serviceName: def
          servicePort: def
      - path: /ghi
        backend:
          serviceName: ghi
          servicePort: ghi
  - host: myseconddomain # <-------- override this via kustomize
    http:
      paths:
      - backend:
          serviceName: xyz
          servicePort: xyz

我想host通过 kustomize声明这些值，以便我可以host为不同的环境指定不同的值。

我的开发环境覆盖补丁文件如下所示：

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: my-ingress
spec:
  rules:
  - host: dev1.example.com
  - host: dev2.example.com

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: my-ingress
spec:
  rules:
  - host: dev1.example.com
  - host: dev2.example.com

但是，运行的输出kustomize build overlays/dev如下所示：

所有其他规格都丢失了。

它最终替换整个 host块而不是只替换host行。

我该如何解决这个问题？我在用：

• 自定义版本v4.1.2
• kubectl版本v1.21.0

# overlays/dev/ingress-json-patch.yaml

- op: replace
  path: /spec/rules/0/host
  value: dev1.example.com
- op: replace
  path: /spec/rules/1/host
  value: dev2.example.com

# overlays/dev/kustomization.yaml
