boto3 set endpoint_url from environment variables

[fatihtekin]

Could you please advise how to set endpoint_url outside of the code by setting an environment variable or a ~/.aws/config file?

[fatihtekin]

I found a workaround to do that as below for boto3. But it would be better if it was as above

from boto3 import Session
Session.client.defaults = (None, None, False, None, 'http://localhost:4575', None, None, None, None)

You can set this during client creation as an argument. Documented here.

There is no environment variable for this but there is nothing stopping you from looking in os.environ yourself and passing that value along to the endpoint_url argument of the client if that is the behavior you want.

Closing as dupe of aws/aws-cli#1270

Could you please reopen this issue? This feature isn't supported currently in boto3.

The dup of aws/aws-cli#1270 has been fixed by an awscli plugin

aws/aws-cli#1270 (comment)

But it only works with aws cli.

It seems the same feature has been added in php sdk as well

https://github.com/aws/aws-sdk-php/pull/1243/files/aeb25899897fe746580ae6c80e0df6ad37931126

If it can work with aws config profile file directly, better than implemented with environment variables, because one python functions can use different endpoint for different aws services.
