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，当我在针对所有OrientDB集群配置的volumeMounts声明中使用子路径时，不会创建pod。尽管我想将所有configMaps装入一个文件夹。 ConfigMap对应于设置OrientDB集群所需的多个配置文件。

StatefulSet看起来像这样：

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

尽管，当我删除StatefulSet中的所有子路径时，会创建pod并将配置文件放置在单独的文件夹中。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

这种行为可能是什么原因？

问题在于，如果部署/状态集中存在子路径字段，即使该字段为空，主机路径卷配置程序中也会存在一个错误，该错误会出现“ lstat：无此类文件或目录”错误。此错误不会让statefulset出现，而是进入containerCreatingConfigErr（在kubeadm上与我一起发生）

这个问题在我遇到的地方也存在。
