数据存储在尝试从泊坞窗容器访问时返回503
我有一个运行Ubuntu 15.10和docker 1.10.1的Google Compute Engine实例。 当我尝试从实例上的gcloud-python访问Google Datastore时，一切正常。 当我尝试从基于python:3.5的docker容器中访问它时python:3.5我总是得到一个503错误。 这是完整的堆栈跟踪：
>>> unit = client.get(key) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.5/site-packages/gcloud/datastore/client.py", line 262, in get deferred=deferred) File "/usr/local/lib/python3.5/site-packages/gcloud/datastore/client.py", line 303, in get_multi transaction_id=transaction and transaction.id, File "/usr/local/lib/python3.5/site-packages/gcloud/datastore/client.py", line 136, in _extended_lookup transaction_id=transaction_id, File "/usr/local/lib/python3.5/site-packages/gcloud/datastore/connection.py", line 200, in lookup _datastore_pb2.LookupResponse) File "/usr/local/lib/python3.5/site-packages/gcloud/datastore/connection.py", line 118, in _rpc data=request_pb.SerializeToString()) File "/usr/local/lib/python3.5/site-packages/gcloud/datastore/connection.py", line 95, in _request raise make_exception(headers, content, use_json=False) gcloud.exceptions.ServiceUnavailable: 503 Backend Error
任何人都可以启发我在这里可能会发生什么？
对于我来说，通过启用“Google Cloud Datastore API（v1beta2）”解决了这个问题。 这不能与“Google Cloud Datastore API”混淆。 为此，您可以转到API Manager概述，search“数据存储”，select“Google Cloud Datastore API（v1beta2）”，然后单击“启用”button。
