elasticsearch - 如何将主机路径装载到有状态集中？

Question

当我事先不知道节点名称时如何将hostPath安装到有状态集中的每个Pod中(因此无法在每个节点上预先创建PV)？
我想在多个节点上建立一个Elasticsearch集群，将每个elasticsearch数据目录安装到主机节点的SSD上...
如何使用有状态集来完成此操作？

对于此类用例，应使用Local Persistent Volume代替HostPath卷。

The biggest difference is that the Kubernetes scheduler understands which node a Local Persistent Volume belongs to. With HostPath volumes, a pod referencing a HostPath volume may be moved by the scheduler to a different node resulting in data loss. But with Local Persistent Volumes, the Kubernetes scheduler ensures that a pod using a Local Persistent Volume is always scheduled to the same node.

考虑为此使用 local static provisioner，它具有 Baremetal environments的说明。
