Node not allowed to joined cluster?


(rene z) #1

For security reasons, is it possible to prevent or not allowing a node to
join a cluster?
With the use of some key.
Bye,
René

You can provide a list of nodes (IP addresses or DNS names) that are
allowed to join the cluster. Other nodes will not be allowed.

Clint,
seems I misinterpreted

I am sorry about that.

When this is not possible, this is considered as a major security issue.
Please Elasticsearch, fix this?
