File

Write to your ~/.aws/credentials file

Weep can write credentials to the AWS shared credential file in your home directory. The AWS CLI and SDKs will refer to this file and use the credentials for a specified profile (or default if none is specified).

Read about AWS configuration settings and precedence for information about precedence of credential sources.

weep file test_account_user --profile default

This will write credentials to your ~/.aws/credentials file that will be used automatically.

cat ~/.aws/credentials

[default]
aws_access_key_id = ASIA4JEFLERSJZDM7YOH
aws_secret_access_key = .....
aws_session_token = .....

Then just run your application or AWS CLI command with the appropriate profile:

AWS_PROFILE=test_account_user aws sts get-caller-identity

# you can also use the --profile flag
aws --profile test_account_user sts get-caller-identity

Profiles can also be set in AWS SDKs. For example in boto3:

import boto3

session = boto3.Session(profile_name="test_account_user")
client = session.client("sts")
print(client.get_caller_identity())
