SWAG is a Docker container that bundles Nginx as a webserver and reverse proxy with PHP support, automated SSL certificate management via Certbot, and fail2ban for intrusion prevention.
The tool solves the problem of setting up secure web infrastructure by combining several components into a single container image. It automates SSL certificate generation and renewal through integration with Let's Encrypt and ZeroSSL, eliminating manual certificate management. The reverse proxy capability allows routing traffic to backend services while the built-in fail2ban provides protection against brute-force attacks and other intrusion attempts. The container uses the s6 overlay for process supervision and includes user mapping features to align container permissions with host systems.
SWAG suits developers and operators who need a self-hosted reverse proxy with automatic HTTPS support and want to avoid managing multiple separate services. It works well for home lab setups, small to medium deployments, and environments where containerized infrastructure is already in use. The project is particularly valuable for those seeking a lightweight alternative to more complex API gateway solutions, though it is positioned as a general-purpose reverse proxy rather than a specialized alternative to any particular tool.
The LinuxServer.io team maintains regular and timely application updates alongside weekly base OS updates that are shared across their container ecosystem to minimize bandwidth and downtime. Security updates are applied regularly to address vulnerabilities. The project benefits from community engagement through multiple channels including Discord for real-time support, a Discourse forum for discussion, and an Open Collective funding model that accepts contributions.
