Server Bootstrap Skill

You help bootstrap remote servers for Docker-based deployments.

Setup

Run bash ${CLAUDE_PLUGIN_ROOT}/scripts/check-deps.sh to verify tools are available.
If .claude/marina-skill.local.md exists, read it for caddy_email. This is used for HTTPS certificate registration.

Scripts

Full bootstrap

CADDY_EMAIL=user@example.com bash ${CLAUDE_PLUGIN_ROOT}/scripts/bootstrap.sh full <server_ip>

This SSHes into the server as root and:

Updates packages, installs unattended-upgrades, jq, git
Installs Docker (if not present)
Creates a deploy user with SSH forced-command restriction
Starts Caddy reverse proxy (auto-HTTPS via Docker labels)
Deploys the deployer and post-receive scripts

Update deployer only

bash ${CLAUDE_PLUGIN_ROOT}/scripts/bootstrap.sh update-deployer <server_ip>

Updates the deployer and post-receive scripts on the server without re-running the full bootstrap.

What Gets Installed

Deploy user

User deploy in the docker group
SSH forced command: /home/deploy/deployer admin
Restrictions: no port forwarding, no X11, no agent forwarding, no PTY
Passwordless sudo

Caddy reverse proxy

Image: lucaslorentz/caddy-docker-proxy:ci-alpine
Ports: 80, 443 (TCP+UDP)
Docker network: caddy
Volumes: caddy_data, caddy_config
Configures itself automatically from Docker container labels
CADDY_EMAIL sets the email for Let's Encrypt certificates

Deployer

Handles incoming git pushes via SSH forced command
Creates bare git repos on first push
Triggers Docker builds via post-receive hook
Restarts containers with Caddy labels for auto-routing

Behavior

Before bootstrapping, verify the server exists and you have its IP
Warn that this SSHes in as root and installs software
Bootstrap takes a few minutes — set expectations
Safe to re-run (all steps are idempotent)
If caddy_email is not configured, ask the user for their email
