What is docker-openvpn-client?

This is a containerized OpenVPN client that lets you route traffic through a VPN without installing VPN software on your computer. The main advantage is flexibility: you can choose which applications use the VPN and which don't, just by deciding whether to connect them to this container's network. It also includes a built-in kill switch, if the VPN connection drops, all traffic from the container is immediately blocked until the VPN reconnects, preventing any data leaks. The container comes with two bonus features: an HTTP proxy server and a SOCKS proxy server. These let other applications and computers on your network access the VPN without needing their own VPN clients. For example, you could configure your browser to use the HTTP proxy and route all your browsing through the VPN, or let a remote machine connect via the SOCKS proxy to access VPN-only resources. You'd use this if you want granular control over which of your applications go through a VPN. Instead of installing OpenVPN on your entire system and managing split tunneling (the messy process of choosing which apps bypass the VPN), you just spin up this container and attach specific applications to it, or connect your other Docker containers to its network. It works with any VPN provider because you supply your own OpenVPN configuration file. Setting it up means running the container with a few special permissions (so it can manage network settings) and pointing it at your VPN config file. From there, you can enable the proxy servers on specific ports and configure other containers to use this one's networking. The README includes code examples for Docker and Docker Compose, along with clear instructions on how to verify everything is working by checking that your traffic actually routes through the VPN.
