How to create ElasticSearch index if it doesn’t already exist in Python

The following utility will create an index if it doesn’t exist already by ignoring any resource_already_exists_exception

def es_create_index_if_not_exists(es, index):
    """Create the given ElasticSearch index and ignore error if it already exists"""
    except elasticsearch.exceptions.RequestError as ex:
        if ex.error == 'resource_already_exists_exception':
            pass # Index already exists. Ignore.
        else: # Other exception - raise it
            raise ex

# Example usage: Create "nodes" index
es_create_index_if_not_exists(es, "nodes")
