In my case, the data stored in elasticsearch must be encrypted.
So i will use dm_crypt + LUKS.
Here is my file system.
In the current state, inserting and searching data using kibana dev tools works fine.
But, I have two questions.
First, Can dm_crypt be used with a elasticsearch basic license?
currently my elastic cluster is a basic license.
The official documentation says that platinum licenses are only supported.
Is there a task to run separately in elasticsearch for dm crypt?
Second, Can server users see data sources(plain text) even using dm_crpyt?
I can connect to the server(login elasticsearch user) and see the text(plain text) of the translog in /var/elasticsearch/data.
Is dm_crypt currently applied?
Or is it not applied because of the license?
