Alias exists API

edit

Checks if an alias exists.

resp = client.indices.exists_alias(
    name="my-alias",
)
print(resp)

response = client.indices.exists_alias(
  name: 'my-alias'
)
puts response

const response = await client.indices.existsAlias({

HEAD _alias/my-alias

Request

edit

HEAD _alias/<alias>

HEAD <target>/_alias/<alias>

Prerequisites

edit

If the Elasticsearch security features are enabled, you must have the view_index_metadata or manage index privilege for the alias. If you specify a target, you must also have the view_index_metadata or manage index privilege for the target.

Path parameters

edit

<alias>: (Optional, string) Comma-separated list of aliases to check. Supports wildcards (*).
<target>: (Optional, string) Comma-separated list of data streams or indices used to limit the request. Supports wildcards (*). To target all data streams and indices, omit this parameter or use * or _all.

Query parameters

edit

expand_wildcards

(Optional, string) Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are:

all: Match any data stream or index, including hidden ones.
open: Match open, non-hidden indices. Also matches any non-hidden data stream.
closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
none: Wildcard patterns are not accepted.

Defaults to all.

ignore_unavailable

(Optional, Boolean) If false, requests that include a missing data stream or index in the <target> return an error. Defaults to false.

Response codes

edit

200: All specified aliases exist.
404: One or more of the specified aliases don’t exist.
