使用Boto3配置文件覆盖S3端点 [英] Overwrite S3 endpoint using Boto3 configuration file

问题描述

我正在尝试使用配置文件(~/aws/confg)覆盖boto3中的某些变量. 在我的用例中，我想使用fakes3服务并将S3请求发送到本地主机.

I'm trying to overwrite certain variables in boto3 using configuration file (~/aws/confg). In my usecase I want to use fakes3 service and send S3 requests to the localhost.

在boto(不是boto3)中，我可以在~/.boto中创建与此配置类似的配置:

In boto (not boto3), I can create a config in ~/.boto similar to this one:

[s3]
host = localhost
calling_format = boto.s3.connection.OrdinaryCallingFormat

[Boto]
is_secure = False

并且客户端可以成功获取所需的更改，而不是将流量发送到真实的S3服务，而是将其发送到本地主机.

And client can successfully pick up desired changes and instead of sending traffic to real S3 service, it will send it to the localhost.

>>> import boto
>>> boto.connect_s3()
S3Connection:localhost
>>> 

我尝试过的事情:

我正在尝试使用boto3库获得相似的结果.通过查看源代码，我发现我可以使用~/aws/config位置.我还在botocore的unittests文件夹中找到了一个示例配置.

WHAT I TRIED:

Im trying to achieve similar result using boto3 library. By looking at the source code I found that I can use ~/aws/config location. I've also found an example config in unittests folder of botocore.

我试图修改配置以实现所需的行为.但不幸的是，它不起作用.

I tried to modify config to achieve desired behaviour. But unfortunately it doesn't work.

这是配置:

[default]
aws_access_key_id = XXXXXXXXX
aws_secret_access_key = YYYYYYYYYYYYYY
region = us-east-1
is_secure = False
s3 =
    host = localhost

问题:

1. 如何使用配置文件覆盖clients变量?
2. 在哪里可以找到配置允许的变量的完整列表?

1. How to overwrite clients variables using config file?
2. Where can I find a complete list of allowed variables for the configuration?

推荐答案

您不能在配置文件中设置主机，但是可以使用boto3从代码中覆盖它.

You cannot set host in config file, however you can override it from your code with boto3.

import boto3

session = boto3.session.Session()

s3_client = session.client(
    service_name='s3',
    aws_access_key_id='aaa',
    aws_secret_access_key='bbb',
    endpoint_url='http://localhost',
)

然后您就可以像往常一样进行互动了.

Then you can interact as usual.

print(s3_client.list_buckets())
