Linux AWS VPN Client with SAML using OpenVPN and Docker

OpenVPN AWS VPN Linux Client in Docker

This is a Docker implementation of the original AWS VPN client PoC with OpenVPN using SAML authentication. The goal is to have an easy to consume Linux client.

See the original blog post for the implementation details.

Content of the repository

• openvpn-v2.4.9-aws.patch - patch required to build AWS compatible OpenVPN v2.4.9, based on the AWS source code (thanks to @heprotecbuthealsoattac) for the link.
• openvpn-v2.5.1-aws.patch - patch for OpenVPN v2.5.1, based on the AWS source code (thanks to @heprotecbuthealsoattac) for the link.
• server.go - Go server to listen on http://127.0.0.1:35001 and save SAML Post data to the file.
• entrypoint.sh - bash wrapper to run OpenVPN. It runs OpenVPN first time to get SAML Redirect and open browser and second time with actual SAML response.

• docker-compose.yml - for running the image properly.

How to use

1. Place AWS configuration file at the same folder of docker-compose.yml, naming it vpn.conf
2. Execute docker-compose up (Better to not use -d option, for getting the login URL in the logs and stopping the container in a easier way)
