要使customize构建在更新网络策略对象时同时考虑同步前操作和同步后操作，您可以在kustomization.yaml文件中使用patch field。这允许您指定应在同步操作之前或之后应用的修补程序。

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
- networkpolicy.yaml
patches:
- path: patch-presync.yaml
  target:
    kind: NetworkPolicy
    name: my-network-policy
  options:
    create: true
- path: patch-postsync.yaml
  target:
    kind: NetworkPolicy
    name: my-network-policy

apiVersion: networking.k8s.io/v1beta1
kind: NetworkPolicy
metadata:
  name: my-network-policy
spec:
  ingress:
  - from:
      - podSelector:
          matchLabels:
            app.kubernetes.io/name: nginx

你可以在Karim Elatov的博客中找到更多信息，如果你想修补多个对象，请遵循doc。
