Secure Settings

edit

Some settings are sensitive, and relying on filesystem permissions to protect their values is not sufficient. For this use case, elasticsearch provides a keystore, which may be password protected, 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.

Creating the keystore

edit

To 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

edit

A list of the settings in the keystore is available with the list command:

bin/elasticsearch-keystore list

Adding string settings

edit

Sensitive 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

edit

To remove a setting from the keystore, use the remove command:

bin/elasticsearch-keystore remove the.setting.name.to.remove
