aws-gate is a tool designed to facilitate secure connections to AWS EC2 instances through AWS Systems Manager (SSM) Session Manager. The tool addresses connectivity challenges by leveraging SSM's session management capabilities to establish secure tunnels to EC2 instances without requiring direct network access or SSH keys. The tool requires Python 3.5 or later and depends on the session-plugin-manager component from AWS SSM Agent version 2.3.68.0 or later to be installed on target EC2 instances. It also requires proper IAM permissions to be configured for the instance profile to enable session management functionality. aws-gate provides a streamlined approach to accessing EC2 instances by utilizing AWS's native session management infrastructure, eliminating the need for traditional SSH key management or VPN connections. The tool integrates with existing AWS authentication mechanisms and leverages the security controls provided by AWS Systems Manager.
