Access S3 using Role in python or command line tool

Hi, @Amit Joshi

do you want to use it on your local machine?

Usually you need an access key and a secret.

Alternatively, you can make Assume Role by linking the identity provider.

For example, if you want to run Python or his commands on his EC2, you can use an EC2 instance profile, in which case you don't need an access key.

https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2_instance-profiles.html

You don't need the Access Key Id and Secret Key in code, you can put them in environment variables or config files and they are used by both the CLI and boto3 in Python. See https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-envvars.html for example.

If you are using CLI, you can create a profile to use IAM role. Refers to documentation at :

https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-role.html

Some of this has been previously stated. You can use aws configure to put your access key and secret key in a file and python and aws cli will find it. If you use a standard location, it will just find it. You can update an environment variable to point to any location on your local computer if you'd like. Here's some documentation on setting this up. Hope this helps even though it's not about using a role. https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html
