elasticsearch-syskeygen

elasticsearch-syskeygen

The elasticsearch-syskeygen command creates a system key file in the elasticsearch config directory.

Synopsis

bin/elasticsearch-syskeygen
[-E <KeyValuePair>] [-h, --help]
([-s, --silent] | [-v, --verbose])

Description

The command generates a system_key file, which you can use to symmetrically encrypt sensitive data. For example, you can use this key to prevent Watcher from returning and storing information that contains clear text credentials. See Encrypting sensitive data in Watcher.

The system key is a symmetric key, so the same key must be used on every node in the cluster.

Parameters

-E <KeyValuePair>

Configures a setting. For example, if you have a custom installation of Elasticsearch, you can use this parameter to specify the ES_PATH_CONF environment variable.

-h, --help

Returns all of the command parameters.

-s, --silent

Shows minimal output.

-v, --verbose

Shows verbose output.

Examples

The following command generates a system_key file in the default $ES_HOME/config directory:
