== Remote Clusters
|
||
|
||
Use *Remote Clusters* to establish a unidirectional
|
||
connection from your cluster to other clusters. This functionality is
|
||
required for {ref}/xpack-ccr.html[cross-cluster replication] and
|
||
{ref}/modules-cross-cluster-search.html[cross-cluster search].
|
||
|
||
To get started, go to *Management > Remote Clusters*.

||
=== Add a remote cluster
|
||
|
||
A {ref}/modules-remote-clusters.html[remote cluster] connection works by configuring a remote cluster and
|
||
connecting to a limited number of nodes, called {ref}/modules-remote-clusters.html#sniff-mode[seed nodes],
|
||
in that cluster.
|
||
Alternatively, you can define a single proxy address for the remote cluster.
|
||
|
||
By default, a cross-cluster request, such as a cross-cluster search or
|
||
replication request, fails if any cluster in the request is unavailable.
|
||
To skip a cluster when its unavailable,
|
||
set *Skip if unavailable* to true.
|
||
|
||
Once you add a remote cluster, you can configure <<managing-cross-cluster-replication, cross-cluster replication>>
|
||
to reproduce indices in the remote cluster on a local cluster.

||

||

|
||
|
||
To create an index pattern to search across clusters,
|
||
use the same syntax that you’d use in a raw cross-cluster search request in {es}: <cluster-names>:<pattern>.
|
||
See <<management-cross-cluster-search, Creating an index pattern>> for examples.

=== Manage remote clusters
|
||
|
||
From the *Remote Clusters* list view, you can drill down into each cluster and
|
||
view its status. You can also edit and delete a cluster.
