Kubernetes 入口 Json 补丁失败

Question

我正在尝试 Json 使用 Kustomize 修补入口但它失败了

入口补丁：

- op: replace
  path: /spec/rules/http/paths/path/backend/serviceName
  value: varnish
- op: replace
  path: /spec/rules/http/paths/path/backend/servicePort
  value: 6091

以下是我的ingress.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: magento-web
  namespace: magento
  annotations:
    kubernetes.io/ingress.class: alb
    alb.ingress.kubernetes.io/certificate-arn: arn:aws:acm:eu-west-2:AccountID:certificate/aaccxsdssa-bbb-434f-b2f9dss-05xxxx51f30
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}, {"HTTPS":443}]'
    alb.ingress.kubernetes.io/actions.ssl-redirect: '{"Type": "redirect", "RedirectConfig": {"Protocol": "HTTPS", "Port": "443", "StatusCode": "HTTP_301"}}'
    alb.ingress.kubernetes.io/scheme: internet-facing
  labels:
    app: magento-web
spec:
  rules:
    - host: training-example.cloud
    - http:
        paths:
          - path: /*
            backend:
              serviceName: magento-web
              servicePort: 80

我尝试过滤 spec 中的项目，但我的补丁仍然失败。我觉得这里有事要做 /spec/rules/http/paths/path/backend/serviceName

kustomize.yaml

bases:
  - ../step-3
  - ../bases/varnish

patchesJson6902:
- path: patch/ingress.yaml
  target:
    group: networking.k8s.io
    version: v1beta1
    kind: Ingress
    name: main
    namespace: magento

configMapGenerator:
- name: aux
  namespace: magento
  behavior: merge
  env: config/aux.env

规则和路径是 JSON-Arrays。所以你需要这个号码。我可以向您推荐一个像 https://jsonpathfinder.com/ 这样的网站，您可以在其中粘贴 json 并深入到您的字段。

这应该有效：

- op: replace
  path: /spec/rules/1/http/paths/0/backend/serviceName
  value: varnish
- op: replace
  path: /spec/rules/1/http/paths/0/backend/servicePort
  value: 6091
