Kustomize - 修补列表中的每个项目

Question

我正在尝试在 Kustomize 中使用修补来修改 Kubernetes 资源，我想知道是否有一种巧妙的方法来更新列表中的每个项目。

这是我想要自定义的 yaml：

apiVersion: admissionregistration.k8s.io/v1
kind: ValidatingWebhookConfiguration
metadata:
  annotations:
  name: validating-webhook-configuration
webhooks:
- admissionReviewVersions:
  - v1
  clientConfig:
    service:
      name: webhook-service
      namespace: rabbitmq-system
      path: /validate-rabbitmq-com-v1beta1-binding
- admissionReviewVersions:
  - v1
  clientConfig:
    service:
      name: webhook-service
      namespace: rabbitmq-system
      path: /validate-rabbitmq-com-v1beta1-exchange
- admissionReviewVersions:
  - v1
  clientConfig:
    service:
      name: webhook-service
      namespace: rabbitmq-system
      path: /validate-rabbitmq-com-v1beta1-federation

这是我想要实现的最终效果（请参阅NEWVALUE）：

apiVersion: admissionregistration.k8s.io/v1
kind: ValidatingWebhookConfiguration
metadata:
  annotations:
  name: validating-webhook-configuration
webhooks:
- admissionReviewVersions:
  - v1
  clientConfig:
    NEWVALUE: value
    service:
      name: webhook-service
      namespace: rabbitmq-system
      path: /validate-rabbitmq-com-v1beta1-binding
- admissionReviewVersions:
  - v1
  clientConfig:
    NEWVALUE: value
    service:
      name: webhook-service
      namespace: rabbitmq-system
      path: /validate-rabbitmq-com-v1beta1-exchange
- admissionReviewVersions:
  - v1
  clientConfig:
    NEWVALUE: value
    service:
      name: webhook-service
      namespace: rabbitmq-system
      path: /validate-rabbitmq-com-v1beta1-federation

我完全了解 Json6902 补丁，但它只允许我一次修改一个索引：

- op: add
  path: /webhooks/0/clientConfig/NEWVALUe
  value: value

有没有办法以类似于 for 循环的方式修改每个元素，或者我是否必须手动指定每个索引？

根据这里讨论的内容，他们还没有支持这种情况。当他们添加它时，你可以这样做：

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

resources:
- validating-webhook.yaml
- configmap.yaml

replacements:
- source:
    kind: ConfigMap
    name: cofignmap
    fieldPath: data.NEWVALUE
  targets:
  - select:
      name: validating-webhook-configuration
      kind: ValidatingWebhookConfiguration
    fieldPaths:
      - webhooks.*.clientConfig.NEWVALUE
    options:
      create: true

配置映射：

apiVersion: v1
kind: ConfigMap
metadata:
  name: cofignmap
data:
  NEWVALUE: value
