"Failed to establish a new connection" 尝试使用 elasticsearch-dsl Python 包访问 Elasticsearch Cloud 时

Question

我正在试验 Elasticsearch 并使用 elasticsearch-dsl Python 包为一些 Django 数据编制索引。

我创建了一个相对基本的测试，search.py，但是当我尝试索引任何数据时收到连接错误。

from elasticsearch_dsl.connections import connections
from elasticsearch_dsl import Document, Text
from elasticsearch.helpers import bulk
from elasticsearch import Elasticsearch

from . import models


connections.create_connection(hosts=['ELASTICSEARCH_ENDPOINT_URL'],
                              http_auth='USERNAME:PASSWORD')


class MyIndex(Document):
    title = Text()
    description = Text()

    class Index:
        name = 'my-index'


def bulk_indexing():
    MyIndex.init()
    es = Elasticsearch()
    bulk(client=es, actions=(a.indexing() for a in models.MyModel.objects.all().iterator()))

当我运行 bulk_indexing() 我得到以下错误：

elasticsearch.exceptions.ConnectionError: ConnectionError(<urllib3.connection.HTTPConnection object at 0x1282266d8>: Failed to establish a new connection: [Errno 61] Connection refused) caused by: NewConnectionError(<urllib3.connection.HTTPConnection object at 0x1282266d8>: Failed to establish a new connection: [Errno 61] Connection refused)

我怀疑语法错误或者我在创建连接时缺少一些凭据，但我找不到任何进一步的信息。

我正在使用通过 Elastic Cloud 部署的 Elasticsearch v7.4.0。当我通过浏览器访问 URL 时，我可以连接。

为什么不直接使用您的 Cloud ID（可以在 ES Cloud 控制台中找到）？

from elasticsearch import Elasticsearch
es = Elasticsearch(cloud_id="<some_long_cloud_id>", http_auth=('USERNAME','PASSWORD'))
