Get AWS Account ID from Boto

Question

I have an AWS_ACCESS_KEY_ID and an AWS_SECRET_KEY. These are active credentials, so they belong to an active user, who belongs to an AWS Account. How, using Boto3, do I fi

Answer 1

Something like this will work:

import boto3

ACCESS_KEY = 'FOO'
SECRET_KEY = 'BAR'

iam = boto3.resource('iam',
    aws_access_key_id=ACCESS_KEY,
    aws_secret_access_key=SECRET_KEY,
)
account_id = iam.CurrentUser().arn.split(':')[4]

print account_id

If you use EC2 IAM roles, you can omit all of the access/secret key stuff and the code becomes simply:

iam = boto3.resource('iam')
account_id = iam.CurrentUser().arn.split(':')[4]
