如何在 Python 中创建不存在的 ElasticSearch 索引

以下实用程序将通过忽略任何 resource_already_exists_exception 在索引不存在时创建它

es_create_index_if_not_exists.py

def es_create_index_if_not_exists(es, index):
    """创建给定的 ElasticSearch 索引，如果已存在则忽略错误"""
    try:
        es.indices.create(index)
    except elasticsearch.exceptions.RequestError as ex:
        if ex.error == 'resource_already_exists_exception':
            pass # 索引已存在。忽略。
        else: # 其他异常 - 抛出它
            raise ex

# 示例用法：创建 "nodes" 索引
es_create_index_if_not_exists(es, "nodes")

def es_create_index_if_not_exists(es, index):
    """创建给定的 ElasticSearch 索引，如果已存在则忽略错误"""
    try:
        es.indices.create(index)
    except elasticsearch.exceptions.RequestError as ex:
        if ex.error == 'resource_already_exists_exception':
            pass # 索引已存在。忽略。
        else: # 其他异常 - 抛出它
            raise ex

# 示例用法：创建 "nodes" 索引
es_create_index_if_not_exists(es, "nodes")
