带有 EKS 集群的 PV 和 PVC

Question

在kubectl apply -f pvc.yaml下面的yaml文件之后，我可以在已经创建的容器中找到挂载路径/var/local/pvctest。但是，工作节点中的主机路径/var/local/pvctest没有创建。

我是使用 EKS 的 PV 和 PVC 的新手，非常感谢任何解决此问题的帮助！

Answer 1

具有 hostPath 的 PersistentVolume 要求主机上的目录为 pre-created。如果您希望自动为您创建目录：

...
containers:
- name: pvctest
  image: neo4j
  ...
  volumeMounts:
  - name: testpv
    mountPath: /var/local/pvctest
volumes:
- name: testpv
  hostPath:
    path: /data
    type: DirectoryOrCreate

PV/PVC 实际上是 hostPath 的可选选项。
