Cloud-init

multi_init() — local Multipass VMs (no UFW). vps_init() — production (UFW, fail2ban, Docker).

_vm = 'testvm'
mi = multi_init(_vm, docker=False)   # docker=False: skip install+reboot, much faster for local testing
print(mi.yaml)

Local testing with Multipass

Requires Multipass installed. Pass cloud_init=mi directly to mp.launch(). Use docker=True in multi_init() if your app needs Docker pre-installed (adds ~2 min for install + reboot).

import tempfile
_app = Path(tempfile.mkdtemp()) / 'myapp'
_app.mkdir()
(_app / 'docker-compose.yml').write_text('services:\n  app:\n    image: nginx:alpine\n')

try: mp.rm(_vm, purge=True)
except: pass
vm = mp.launch(_vm, image='24.04', cpus=1, memory='1G', disk='10G', cloud_init=mi)
ip = mp.ip(vm.name)
print(f'VM at {ip}, key: {vm.key}')

Provision and deploy on Hetzner

Set HCLOUD_TOKEN in your environment. hetzner_deploy() provisions the server, waits for cloud-init, and deploys in one call. It’s idempotent — re-running against an existing server just redeploys.

hz = Hetzner()
svr = hetzner_deploy('myapp-prod',_app, hz) # hz is not required
print(f'Deployed at {svr.name}, key: {svr.key}')

Docker Compose helpers

Any app that dockeasy can build — FastHTML, FastAPI, Go, Rust, Node — follows the same production Compose shape when deployed behind Cloudflare Tunnel: an app service, a caddy reverse proxy, a cloudflared tunnel container, a shared web network, and two named volumes for Caddy state.

caddy_stack() generates that structure from a domain and any dockeasy Dockerfile object. vols_to_binds() converts absolute container paths to local bind mounts. The root= argument saves all three files (Dockerfile, docker-compose.yml, Caddyfile); without it the Compose object is returned without writing anything.

d = Path(tempfile.mkdtemp())
df = fasthtml_app(pkgs=['sqlite3'], vols=['/app/data'], healthcheck='/health')
c = caddy_stack('myapp.example.com', df, vols=['/app/data'], root=d)
print(c)

Install agent skill

Copies SKILL.md to .agents/skills/vpseasy/ (project-local) and ~/.claude/skills/vpseasy/ (global Claude Code).

mv_skill_md(dry_run=True)

Would copy to: ['.agents/skills/vpseasy/SKILL.md', '/Users/71293/.claude/skills/vpseasy/SKILL.md']
