Open Distro for Elasticsearch development has moved to OpenSearch. The ODFE plugins will continue to work with legacy versions of Elasticsearch OSS, but we recommend upgrading to OpenSearch to take advantage of the latest features and improvements.
Encryption at rest
The operating system for each Open Distro for Elasticsearch node handles encryption of data at rest. To enable encryption at rest in most Linux distributions, use the
cryptsetup luksFormat --key-file <key> <partition>
For full documentation on the command, see the Linux man page.
