boto3找不到配置文件

如何解决boto3找不到配置文件

我的boto3设置可以通过/.aws/credentials提供凭据-我想如何将其作为环境变量传递给docker工作。

这是/.aws/credentials

的内容

[default]
aws_access_key_id = ABCD123
aws_secret_access_key = BCDSA123

[testing]
source_profile = default
role_arn = arn:aws:iam::123:role/access-db

一切正常-但如果我在aws.env文件中设置安装环境变量

export AWS_ACCESS_KEY_ID="ABCD123"
export AWS_SECRET_ACCESS_KEY="BCDSA123"
export AWS_ROLE_SESSION_NAME="default"
export AWS_PROFILE="testing"
export AWS_DEFAULT_PROFILE="testing"
export AWS_ROLE_ARN="arn:aws:iam::123:role/access-db"

我收到以下错误

    raise ProfileNotFound(profile=profile_name)
botocore.exceptions.ProfileNotFound: The config profile (testing) could not be found

这是我的python脚本

import boto3
import os

boto3.setup_default_session(profile_name = 'testing')
s3 = boto3.resource('s3')
s3_client = boto3.client('s3')
my_bucket = s3.Bucket('ds-models-testing')

我希望与之合作的

-再一次，似乎我的环境变量中缺少某些东西，并且boto正在搜索配置文件botocore.exceptions.ProfileNotFound: The config profile (testing) could not be foun

解决方法

您没有配置文件。配置和凭据文件应位于〜/ .aws文件夹中。

.aws /凭证

[default]
aws_access_key_id = ABCD123
aws_secret_access_key = BCDSA123

和配置文件.aws / config

[profile testing]
source_profile = default
role_arn = arn:aws:iam::123:role/access-db

,

首先，我认为如果要尝试从环境变量中读取内容，则应删除此行：

boto3.setup_default_session(profile_name = 'testing')

文档说

Boto3搜索凭据的顺序为：

1. Passing credentials as parameters in the boto.client() method
2. Passing credentials as parameters when creating a Session object
3. Environment variables
4. Shared credential file (~/.aws/credentials)
5. AWS config file (~/.aws/config)
6. Assume Role provider
7. Boto2 config file (/etc/boto.cfg and ~/.boto)
8. Instance metadata service on an Amazon EC2 instance that has an IAM role configured.

参考：https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html

因此，您怀疑环境变量很可能没有按预期设置。尝试添加代码以记录通过app.env文件设置的环境变量的值，以确保您确实看到了它的设置并可以将其读取为环境变量：

os.environ.get('AWS_ACCESS_KEY_ID','It is not set!')

假设它实际上正在读取您在aws.env中设置的环境变量，然后尝试仅导出aws.env中的这两个环境变量并删除其他环境变量：

export AWS_ACCESS_KEY_ID="ABCD123"
export AWS_SECRET_ACCESS_KEY="BCDSA123"

,

您需要取消设置AWS_PROFILE环境变量。
