Kubernetes 如何使用kustomize将内存中的存储替换为持久存储

我正在尝试使用

kustomize

将

Grafana

部署的内存存储替换为

持久存储

。我试图做的是删除

内存存储

，然后映射

持久存储

。但当我部署它时，它会给我一个错误

错误

部署“grafana”无效：spec.template.spec.containers[0]。volumeMounts[1]。名称：未找到：“grafana存储”

-$patch:delete这个

$patch:delete

似乎不像我预期的那样工作

在kustomize github上打开一个问题并询问开发人员可能会很好

---

虽然这是我尝试过的补丁，而且似乎有效：

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: grafana
  name: grafana
  namespace: monitoring
spec:
  template:
    spec:
      volumes:
        - name: grafana-storage
          emptyDir: null
          persistentVolumeClaim:
            claimName: grafana-storage
      containers:
        - name: grafana
          volumeMounts:
            - name: grafana-storage
              mountPath: /var/lib/grafana

---

基于

从理论上讲，以下几点也应该起作用：

spec:
  volumes:
    - $retainKeys:
      - name
      - persistentVolumeClaim
      name: grafana-storage
      persistentVolumeClaim:
        claimName: grafana-storage

但实际上并非如此，我认为这是因为kustomize有自己的战略合并实现（与k8s不同）。

非常感谢您的帮助。我尝试了您在

部署中提到的方法，效果很好。非常感谢你。删除了
$patch:delete
部分。仅供参考：我已将建议的问题提交给kustomize Peoples:，让我们看看。
