aws bulk-cli

A thin wrapper around AWS CLI that enables running AWS CLI commands on multiple AWS accounts.

Prerequisites

• AWS CLI

Configuration

CLI Options

Option	Description
accounts	Comma-delimited list of AWS accounts
cross-account-role-name	Name of cross-account IAM role used to access AWS accounts
config	Path to aws bulk-cli config file.
region	AWS region to run aws bulk-cli
profile	Named profile to use to run aws bulk-cli

Config File

aws bulk-cli can be configured with a json file.

Config File Template

{
    "aws": {
        "profile": "profile_name",
        "region": "region_name",
        "cross-account-role-name": "role_name",
        "accounts": [
            "000000000000", 
            "111111111111"
        ]
    }
}

How it works

1. Iterates over the list of AWS accounts
2. Assume role arn:aws:iam::<account_id>:role/<cross-account-role-name>
3. Run command in AWS account
4. Wait for each command in all accounts to return
5. Display command result
