slip

A container docking for your server.

slip is a lightweight deployment daemon written in Rust. It runs on your server, accepts deploy webhooks from CI, and manages zero-downtime container deployments using Caddy as the reverse proxy.

No SSH keys in CI. No PaaS overhead. No Kubernetes.

How it works

GitHub Actions → signed webhook → slipd → pull image → start container → health check → update Caddy → stop old

1. CI builds your image and pushes to GHCR
2. CI sends a signed HTTP POST to your server
3. slipd pulls the image, starts a new container, health checks it
4. If healthy: swaps the Caddy route, drains old connections, stops the old container
5. If unhealthy: stops the new container, keeps the old one running

Status

Early development. See docs/prd.md for the full product spec and docs/slip-design.md for the architecture design doc.

Project Structure

Cargo workspace with three crates:

• slipd — the deploy daemon (receives webhooks, manages containers, talks to Caddy)
• slip — the CLI (app management, secrets, status, manual deploys)
• slip-core — shared library (config, types, Docker/Caddy clients)
