我有一个boto3客户端:

boto3.client('kms')

但这发生在新机器上,它们动态地打开和关闭。

    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?为什么只是部分时间?

地区= [ “eu-north-1”、“ap-south-1’,‘eu-west-3’,‘eu-west-2’, 'eu-west-1', 'ap-northeast-3', 'ap-northeast-2' 'ap-northeast-1' 'sa-east-1' 'ca-central-1', “ap-southeast-2”、“eu-central-1’,‘us-east-1’,‘us-east-2’, “us-west-1”、“us-west-2 '] 对于地区: KMS = boto3。客户端('kms', region_name= r)

您还可以在脚本本身中设置环境变量,而不是传递region_name参数

操作系统。environ['AWS_DEFAULT_REGION'] = 'your_region_name'

大小写敏感性可能很重要。

您也可以运行以下命令(aws cli)

aws configure --profile $PROFILE_NAME

它会提示您输入区域。

注意~/。aws /配置是:

[default]
region = ap-southeast-1
output = json

[profile prod]
region = ap-southeast-1
output = json

[profile配置文件名称]

我们将配置好的区域存储在~/中。aws /配置文件。下面是一个纯python的方法,根据配置文件名称从这个文件中读取正确的区域:

def get_aws_region(profile_name: str) -> str:
  config = configparser.ConfigParser()
  config.read(f"{os.environ['HOME']}/.aws/config")
  profile_section = config[f"profile {profile_name}"]
  return profile_section["region"]

地区= [ “eu-north-1”、“ap-south-1’,‘eu-west-3’,‘eu-west-2’, 'eu-west-1', 'ap-northeast-3', 'ap-northeast-2' 'ap-northeast-1' 'sa-east-1' 'ca-central-1', “ap-southeast-2”、“eu-central-1’,‘us-east-1’,‘us-east-2’, “us-west-1”、“us-west-2 '] 对于地区: KMS = boto3。客户端('kms', region_name= r)

如果你愿意,你可以总是将它设置为EC2所在的相同区域。这是用bash,但你可以很容易地在python中重现:

EC2_AVAIL_ZONE=$(curl -s http://169.254.169.254/latest/meta-data/placement/availability-zone)
EC2_REGION="`echo $EC2_AVAIL_ZONE | sed -e 's:\([0-9][0-9]*\)[a-z]*\$:\\1:'`"
# if unset, set it:
export AWS_DEFAULT_REGION="${AWS_DEFAULT_REGION:-$EC2_REGION}"

python:

import os
import re
from subprocess import check_output

EC2_AVAIL_ZONE = check_output(["curl", "-s", "http://169.254.169.254/latest/meta-data/placement/availability-zone"]).decode().strip()
EC2_REGION = re.sub(r"^(\w{2}-\w{3,10}-[0-9][0-9]*)[a-z]*$", r"\1", EC2_AVAIL_ZONE)
# if unset, set it:
os.environ["AWS_DEFAULT_REGION"] = os.getenv("AWS_DEFAULT_REGION", EC2_REGION)
