== Nodes Reload Secure Settings
|
||
|
|
|
||
|
|
The cluster nodes reload secure settings API is used to re-read the
|
||
|
|
local node's encrypted keystore. Specifically, it will prompt the keystore
|
||
|
|
decryption and reading accross the cluster. The keystore's plain content is
|
||
|
|
used to reinitialize all compatible plugins. A compatible plugin can be
|
||
|
|
reinitilized without restarting the node. The operation is
|
||
|
|
complete when all compatible plugins have finished reinitilizing. Subsequently,
|
||
|
|
the keystore is closed and any changes to it will not be reflected on the node.

||

POST _nodes/reload_secure_settings
|

|
|
POST _nodes/nodeId1,nodeId2/reload_secure_settings
|
||
|

--------------------------------------------------
|
||
|
|
// CONSOLE
|
||
|
|
// TEST[setup:node]
|
||
|
|
// TEST[s/nodeId1,nodeId2/*/]
|
||
|
|
|
||
|
|
The first command reloads the keystore on each node. The seconds allows
|
||
|
|
to selectively target `nodeId1` and `nodeId2`. The node selection options are
|
||
|
|
detailed <<cluster-nodes,here>>.
|
||
|
|
|
||
|
|
Note: It is an error if secure settings are inconsistent across the cluster
|
||
|
|
nodes, yet this consistency is not enforced whatsoever. Hence, reloading specific
|
||
|
|
nodes is not standard. It is only justifiable when retrying failed reload operations.

==== REST Reload Secure Settings Response
|
||
|
|
|
||
|
|
The response contains the `nodes` object, which is a map, keyed by the
|
||
|
|
node id. Each value has the node `name` and an optional `reload_exception`
|
||
|
|
field. The `reload_exception` field is a serialization of the exception
|
||
|
|
that was thrown during the reload process, if any.
