Kubernetes 中 OrientDB 的 StatefulSet 卷挂载

Question

我正在尝试使用 Kubernetes（特别是 minikube）部署 OreintDB 集群。我正在使用 StatefulSet，但是，当我在所有 OrientDB 集群配置的 volumeMounts 声明中使用子路径时，不会创建 pods。虽然我想将所有 configMaps 挂载到一个文件夹中。 ConfigMaps对应设置OrientDB集群所需的多个配置文件。

StatefulSet 如下所示：

volumeMounts:
    - name: orientdb-config-backups
      mountPath: /orientdb/config
      subPath: backups
    - name: orientdb-config-events
      mountPath: /orientdb/config
      subPath: events
    - name: orientdb-config-distributed
      mountPath: /orientdb/config
      subPath: distributed
    - name: orientdb-config-hazelcast
      mountPath: /orientdb/config
      subPath: hazelcast
    - name: orientdb-config-server
      mountPath: /orientdb/config
      subPath: server
    - name: orientdb-config-client-logs
      mountPath: /orientdb/config
      subPath: client-logs
    - name: orientdb-config-server-logs
      mountPath: /orientdb/config
      subPath: server-log
    - name: orientdb-databases
      mountPath: /orientdb/databases
    - name: orientdb-backup
      mountPath: /orientdb/backup

虽然，当我删除 StatefulSet 中的所有子路径时，会创建 pods 并将配置文件放入单独的文件夹中。所以 StatefulSet 看起来像这样：

volumeMounts:
- name: orientdb-config-backups
  mountPath: /orientdb/config/backups
- name: orientdb-config-events
  mountPath: /orientdb/config/events
- name: orientdb-config-distributed
  mountPath: /orientdb/config/distributed
- name: orientdb-config-hazelcast
  mountPath: /orientdb/config/hazelcast
- name: orientdb-config-server
  mountPath: /orientdb/config/server
- name: orientdb-config-client-logs
  mountPath: /orientdb/config/client-logs
- name: orientdb-config-server-logs
  mountPath: /orientdb/config/server-logs
- name: orientdb-databases
  mountPath: /orientdb/databases
- name: orientdb-backup
  mountPath: /orientdb/backup
- name: orientdb-data
  mountPath: /orientdb/bin/data

这种行为的原因可能是什么？

问题是主机路径卷供应器中存在错误，如果 deployment/statefulset 中存在子路径字段，即使该字段为空，也会遇到 "lstat: no such file or directory" 错误。这个错误不会让 statefulset 出现，它们会进入 containerCreatingConfigErr（我在 kubeadm 上遇到过）

这个问题在 kubeadm 上也存在，我也遇到过。
