Amazon EKS (NFS) to Kubernetes pod.无法装入卷

Question

我正在使用terraform将Amazon EKS(NFS(连接到Kubernetes pod。

一切运行时都没有错误，并已创建：

• 吊舱胜利者
• 存储类
• 持久卷
• 持续数量声明

但是，卷victoriametrics-data未连接到pod。不管怎样，我在吊舱的外壳里看不到一个。有人能帮我理解我错在哪里吗？

我为这个问题剪切了一些不重要的代码，以缩短代码。

Answer 1

您需要使用您在部署中创建的持久卷声明，而不是emptyDir：

kind: Deployment
apiVersion: apps/v1
metadata:
name: victoriametrics
...
volumes:
- name: victoriametrics-data
persistentVolumeClaim:
claimName: <value of local.name_persistent_volume_claim>
