The elasticsearch-keystore command manages secure settings in the Elasticsearch keystore.

Synopsisedit

bin/elasticsearch-keystore
([add <setting>] [--stdin] |
[add-file <setting> <path>] | [create] |
[list] | [remove <setting>] | [upgrade])
[-h, --help] ([-s, --silent] | [-v, --verbose])

Descriptionedit

Currently, all secure settings are node-specific settings that must have the same value on every node. Therefore you must run this command on every node.

Modifications to the keystore do not take effect until you restart Elasticsearch.

Only some settings are designed to be read from the keystore. However, there is no validation to block unsupported settings from the keystore and they can cause Elasticsearch to fail to start. To see whether a setting is supported in the keystore, see the setting reference.

Parametersedit

Examplesedit

Create the keystoreedit

To create the elasticsearch.keystore, use the create command:

bin/elasticsearch-keystore create

A elasticsearch.keystore file is created alongside the elasticsearch.yml file.

List settings in the keystoreedit

To list the settings in the keystore, use the list command.

bin/elasticsearch-keystore list

Add settings to the keystoreedit

Sensitive string settings, like authentication credentials for Cloud plugins, can be added with the add command:

bin/elasticsearch-keystore add the.setting.name.to.set

You are prompted to enter the value of the setting. To pass the value through standard input (stdin), use the --stdin flag:

cat /file/containing/setting/value | bin/elasticsearch-keystore add --stdin the.setting.name.to.set

Add files to the keystoreedit

You can add sensitive files, like authentication key files for Cloud plugins, using the add-file command. Be sure to include your file path as an argument after the setting name.

bin/elasticsearch-keystore add-file the.setting.name.to.set /path/example-file.json

Remove settings from the keystoreedit

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

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

Upgrade the keystoreedit

Occasionally, the internal format of the keystore changes. When Elasticsearch is installed from a package manager, an upgrade of the on-disk keystore to the new format is done during package upgrade. In other cases, Elasticsearch performs the upgrade during node startup. This requires that Elasticsearch has write permissions to the directory that contains the keystore. Alternatively, you can manually perform such an upgrade by using the upgrade command:

bin/elasticsearch-keystore upgrade
