Client Settings

The client that you use to connect to S3 has a number of settings available. The settings have the form s3.client.CLIENT_NAME.SETTING_NAME. The default client name that is looked up by an s3 repository is default. It can be modified using the repository setting client. For example:

PUT _snapshot/my_s3_repository
{
  "type": "s3",
  "settings": {
    "bucket": "my_bucket",
    "client": "my_alternate_client"
  }
}

Most client settings can be added to the elasticsearch.yml configuration file with the exception of the secure settings, which you add to the Elasticsearch keystore. For more information about creating and updating the Elasticsearch keystore, see Secure settings.

For example, to use explicit AWS access keys:

bin/elasticsearch-keystore add s3.client.default.access_key
bin/elasticsearch-keystore add s3.client.default.secret_key

The following list contains the available client settings. Those that must be stored in the keystore are marked as "secure"; the other settings belong in the elasticsearch.yml file.
