Client Settingsedit

The client used to connect to Google Cloud Storage has a number of settings available. Client setting names are of the form gcs.client.CLIENT_NAME.SETTING_NAME and are specified inside elasticsearch.yml. The default client name looked up by a gcs repository is called default, but can be customized with the repository setting client.

For example:

PUT _snapshot/my_gcs_repository
{
  "type": "gcs",
  "settings": {
    "bucket": "my_bucket",
    "client": "my_alternate_client"
  }
}

Some settings are sensitive and must be stored in the Elasticsearch keystore. This is the case for the service account file:

bin/elasticsearch-keystore add-file gcs.client.default.credentials_file

The following are the available client settings. Those that must be stored in the keystore are marked as Secure.

credentials_file
The service account file that is used to authenticate to the Google Cloud Storage service. (Secure)
endpoint
The Google Cloud Storage service endpoint to connect to. This will be automatically determined by the Google Cloud Storage client but can be specified explicitly.
connect_timeout
The timeout to establish a connection to the Google Cloud Storage service. The value should specify the unit. For example, a value of 5s specifies a 5 second timeout. The value of -1 corresponds to an infinite timeout. The default value is 20 seconds.
read_timeout
The timeout to read data from an established connection. The value should specify the unit. For example, a value of 5s specifies a 5 second timeout. The value of -1 corresponds to an infinite timeout. The default value is 20 seconds.
application_name
Name used by the client when it uses the Google Cloud Storage service. Setting a custom name can be useful to authenticate your cluster when requests statistics are logged in the Google Cloud Platform. Default to repository-gcs
project_id
The Google Cloud project id. This will be automatically inferred from the credentials file but can be specified explicitly. For example, it can be used to switch between projects when the same credentials are usable for both the production and the development projects.
