aws_tgw_details 1.0.15

Get AWS Transit Gateway details.

Overview

Get AWS Transit Gateway details.

This module helps to retrieve AWS Transit Gateway details, including the following:

• Transit Gateways

• Transit Gateway Route Tables

• Transit Gateway Routes

• Transit Gateway Attachments

• Customer Gateways

• VPN Connections

The aws_authenticator module is installed with this module, and is used to login to AWS using IAM access key credentials from the following environment variables:

• TGW_AWS_ACCESS_KEY_ID

• TGW_AWS_SECRET_ACCESS_KEY

• TGW_AWS_SESSION_TOKEN (Optional. Default: None.)

If the environment variables are not set, the module will try to use the default AWS credentials from the AWS CLI configuration file.

Usage

• Installation:

pip3 install aws_tgw_details
# or
python3 -m pip install aws_tgw_details

• Set environment variables:

export TGW_AWS_ACCESS_KEY_ID=your_access_key_id
export TGW_AWS_SECRET_ACCESS_KEY=your_secret_access_key
export TGW_AWS_SESSION_TOKEN=your_session_token

• Examples:

# Overview.
aws_tgws

# Help.
aws_tgws -h

# Get all Transit Gateways.
aws_tgws -t ALL

# Get a specific Transit Gateway.
aws_tgws -t tgw-1234567890abcdef0

# Get all Customer Gateways.
aws_tgws -c ALL

You can also use the available functions independently to create your own workflow instead of using the installed aws_tgws command line tool.
