boto3客户端NoRegionError:仅在某些情况下必须指定区域错误 [英] boto3 client NoRegionError: You must specify a region error only sometimes

问题描述

我有一个boto3客户端:

I have a boto3 client :

boto3.client('kms')

但是它发生在新机器上，它们会动态打开和关闭.

But it happens on new machines, They open and close dynamically.

    if endpoint is None:
        if region_name is None:
            # Raise a more specific error message that will give
            # better guidance to the user what needs to happen.
            raise NoRegionError()

为什么会这样?为什么只有部分时间呢?

Why is this happening? and why only part of the time?

推荐答案

您必须以一种或另一种方式告诉boto3您希望在哪个区域创建kms客户端.可以使用region_name参数明确完成此操作，如下所示:

One way or another you must tell boto3 in which region you wish the kms client to be created. This could be done explicitly using the region_name parameter as in:

kms = boto3.client('kms', region_name='us-west-2')

，或者您可以在~/.aws/config文件中将与您的个人资料相关联的默认区域设置为:

or you can have a default region associated with your profile in your ~/.aws/config file as in:

[default]
region=us-west-2

或者您可以使用如下环境变量:

or you can use an environment variable as in:

export AWS_DEFAULT_REGION=us-west-2

但是您确实需要告诉boto3使用哪个区域.

but you do need to tell boto3 which region to use.
