Secure Settings
editSecure Settings
editSome settings are sensitive, and relying on filesystem permissions to protect
their values is not sufficient. For this use case, Elasticsearch provides a
keystore and the elasticsearch-keystore tool to manage the settings in the keystore.
All commands here should be run as the user which will run elasticsearch.
Only some settings are designed to be read from the keystore. See documentation for each setting to see if it is supported as part of the keystore.
All the modifications to the keystore take affect only after restarting Elasticsearch.
The elasticsearch keystore currently only provides obfuscation. In the future, password protection will be added.
Creating the keystore
editTo create the elasticsearch.keystore, use the create command:
bin/elasticsearch-keystore create
The file elasticsearch.keystore will be created alongside elasticsearch.yml.
Listing settings in the keystore
editA list of the settings in the keystore is available with the list command:
bin/elasticsearch-keystore list
Adding string settings
editSensitive string settings, like authentication credentials for cloud
plugins, can be added using the add command:
bin/elasticsearch-keystore add the.setting.name.to.set
The tool will prompt for the value of the setting. To pass the value
through stdin, use the --stdin flag:
cat /file/containing/setting/value | bin/elasticsearch-keystore add --stdin the.setting.name.to.set
Removing settings
editTo remove a setting from the keystore, use the remove command:
bin/elasticsearch-keystore remove the.setting.name.to.remove
