Question

我正在使用kustomize并尝试将一些头盔参数修补到grafana配置中，我具有以下配置文件grafana.yaml：

---
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: prod-k8s-grafana
  labels:
    environment: prod
    project: k8s
    role: grafana
spec:
  project: prod-k8s
  source:
    repoURL: 'https://github.com/helm/charts.git'
    path: 'stable/grafana'
    targetRevision: 'ba1d08a129255167457480e29339ab5bfe75d918'
    helm:
      parameters:
      - name: service.type
        value: LoadBalancer
  syncPolicy:
    automated:
      prune: true
  destination:
    namespace: prod-k8s-grafana

然后，我有了我的kustomization文件，该文件用于添加修补值-专门添加到头盔参数部分。当我添加如下所示的补丁程序时，它会修补值，但会删除grafana.yaml文件中定义的原始名称值：

patches:
- target:
    kind: Application
  patch: |-
    apiVersion: argoproj.io/v1alpha1
    kind: Application
    metadata:
      name: xxx
    spec:
      destination:
        server: https://DSKJHDAKJSH4HDSKHDKSJ0E56C7420CCF041E9.sk1.eu-west-2.eks.amazonaws.com
- target:
    kind: Application
    name: prod-k8s-grafana
  patch: |-
    apiVersion: argoproj.io/v1alpha1
    kind: Application
    metadata:
      name: prod-k8s-grafana
    spec:
      source:
        helm:
          parameters:
          - name: 'datasources."datasources\.yaml".datasources[0].url'
            value: 'http://prod-k8s-prometheus-cluster02-server.prod-k8s-prometheus.svc.cluster.local'
          - name: persistence.storageClassName
            value: gp2
          - name: 'datasources."datasources\.yaml".apiVersion'
            value: '1'
          - name: 'datasources."datasources\.yaml".datasources[0].name'
            value: Prometheus

这样，当我检查运行kustomize build命令时，它将删除输出：

      - name: service.type
        value: LoadBalancer

因此，修补这些名称和值似乎会覆盖grafana.yaml中的参数。

如何确保补丁在补丁名称后附加一个值，而不是覆盖？

我最近遇到了同样的问题，不知道这是否是完美的解决方案，但是如果您使用patchesJson6902并在0位置添加env变量，则不会删除另一个变量：

- op: add
  path: /spec/template/spec/containers/0/env/0
  value:
    name: ONE
    value: '1'
- op: add
  path: /spec/template/spec/containers/0/env/0
  value:
    name: TWO
    value: '2'
- op: add
  path: /spec/template/spec/containers/0/env/0
  value:
    name: THREE
    value: '3'

kustomize补丁程序覆盖参数名称和值
