woosh 0.1.0

Agentic auto-deployer: scan a project + VM, propose a deployment plan, confirm, then ship it behind a reverse proxy — one command.

woosh

One command — woosh install — that scans a project and the host it's running on, has an LLM agent plan the deployment, shows you the plan, and only then deploys behind a shared reverse proxy (Caddy or Nginx).

Install

pip install -e .

First run triggers onboarding automatically; or run it explicitly:

woosh init

This asks for your OpenAI API key and which model to use, then stores them at ~/.woosh/config.json (owner-only file permissions, chmod 600). You can also skip onboarding by exporting OPENAI_API_KEY yourself.

Use

cd your-project
woosh install

Flow:

1. Scan (deterministic, no LLM involved) — project files (docker-compose.yml, Dockerfile, .env*), host's listening TCP ports, running containers, existing docker networks.
2. Plan — the agent (OpenAI tool-calling loop) reasons over the scan and calls propose_plan. It can call ask_user mid-reasoning if it's missing something (domain name, TLS on/off, how to resolve a port clash). It has read-only tools in this phase — it cannot write or run anything yet.
3. Confirm — the plan is printed (strategy, steps, flagged [risky] steps, port conflicts, a diff of any docker-compose.yml changes). You approve or abort. Nothing is touched until you say yes.
4. Execute — only now does the agent get write_file / run_shell / health_check. run_shell is whitelisted at the argv level to docker/docker-compose only. Any destructive action not already in the approved plan (stopping an unrelated container, pruning, deleting a volume) still requires a fresh ask_user confirmation.

Why a shared reverse proxy

On a VM running multiple deployments, the agent is instructed to prefer attaching new services to one shared Caddy (or Nginx) instance on an external docker network (woosh_proxy) rather than spinning up a proxy per project — that's what avoids the "everything wants port 80/443" problem permanently. It only proposes installing a fresh shared proxy if neither is already running on the host.

Notes / next steps

• The OpenAI key is stored in plaintext JSON with chmod 600. For a more hardened setup, swap config.py to use the keyring package (OS keychain) instead — the rest of the code doesn't care where the key comes from.
• scan_listening_ports() uses psutil; process-name resolution can be incomplete without root on some systems, but port numbers are always accurate.
• TLS: Caddy defaults to automatic HTTPS for real domains; pass tls: "internal" in a route for self-signed/local certs.
