Index template exists API

This documentation is about legacy index templates, which are deprecated and will be replaced by the composable templates introduced in Elasticsearch 7.8. For information about composable templates, see Index templates.

Checks if an legacy index template exists.

response = client.indices.exists_template(
  name: 'template_1'
)
puts response
HEAD /_template/template_1

Prerequisites

  • If the Elasticsearch security features are enabled, you must have the manage_index_templates or manage cluster privilege to use this API.

Description

Use the index template exists API to determine whether one or more index templates exist.

Index templates define settings, mappings, and aliases that can be applied automatically to new indices.

Path parameters

<index-template>
(Required, string) Comma-separated list of index template names used to limit the request. Wildcard (*) expressions are supported.

Query parameters
