Kubernetes持久卷在GCE上不起作用
我正在尝试使我的弹性search窗格保持不变，以便在部署或窗格重新创build时保留数据。弹性search是Graylog2设置的一部分。
在完成所有设置后，我向Graylog发送了一些日志，我可以看到它们出现在仪表板上。 但是，我删除了elasticsearch pod，在重新创build之后，所有的数据在Graylog仪表板上都丢失了。
我正在使用GCE。
这是我的永久卷configuration：
kind: PersistentVolume apiVersion: v1 metadata: name: elastic-pv labels: type: gcePD spec: capacity: storage: 200Gi accessModes: - ReadWriteOnce gcePersistentDisk: fsType: ext4 pdName: elastic-pv-disk 持续音量声明configuration：
kind: PersistentVolumeClaim apiVersion: v1 metadata: name: elastic-pvc labels: type: gcePD spec: accessModes: - ReadWriteOnce resources: requests: storage: 200Gi
这里是我的elasticsearch部署：

kubectl describe pod输出kubectl describe pod ：

确认真实磁盘存在：
永久卷不持久的原因是什么？
在官方图像中，Elasticsearch数据存储在/usr/share/elasticsearch/data而不是/data/db 。 看起来你需要更新挂载为/usr/share/elasticsearch/data而不是将数据存储在持久卷上。
