-# Ship v2
-**Ship is a deployment tool built for AI agents.**
-Agents write code. Ship puts it on the internet. That's it.
-## The Problem
-AI agents can write code, but deploying it is a mess:
- Vercel/Railway/Fly require accounts, API tokens, platform-specific config
- Docker/K8s are overkill for "make this code accessible via URL"
- Most tools assume a human is reading the output
-Agents need: code → URL. Nothing else.
-## Ship's Approach
-```bash
-ship ./myproject
-# {"status":"ok","url":"https://abc123.example.com","took_ms":4200}
-```
-**That's the entire interface.** Point ship at code, get a URL back as JSON.
-### Core Principles
-1. **JSON in, JSON out** — No human-formatted output. No spinners. No emoji. Agents parse JSON.
-2. **One command** — No workflows. No "init then configure then deploy." One command does everything.
-3. **Verify or fail** — Every deploy is health-checked. If the app isn't responding, ship returns an error. No silent failures.
-4. **Self-cleaning** — Deploys can auto-expire. Agents create lots of previews; they shouldn't pile up forever.
-5. **Zero config** — Point at a directory. Ship figures out if it's static, Docker, or a binary. No config files required.
-6. **SSH-only** — No accounts. No API tokens. No vendor lock-in. Just SSH access to a VPS.
-## Interface
-### Deploy
-```bash
-ship ./myproject
-ship ./myproject --name myapp
-ship ./myproject --name preview --ttl 24h
-ship ./site --static
-ship ./api --health /healthz
-```
-Output:
-```json
-{
-  "status": "ok",
-  "name": "myapp",
-  "url": "https://myapp.example.com",
-  "type": "docker",
-  "took_ms": 4200,
-  "health": {"status": 200, "latency_ms": 45}
-}
-```
-### Error
-```json
-{
-  "status": "error",
-  "code": "HEALTH_CHECK_FAILED",
-  "message": "GET /healthz returned 503 after 30s",
-  "name": "myapp",
-  "url": "https://myapp.example.com"
-}
-```
-### List
-```bash
-ship list
-```
-```json
-{
-  "status": "ok",
-  "deploys": [
-    {"name": "api", "url": "https://api.example.com", "type": "docker", "running": true},
-    {"name": "preview-x7k", "url": "https://preview-x7k.example.com", "type": "static", "expires": "2024-02-16T18:00:00Z"}
-  ]
-}
-```
-### Status / Logs / Remove
-```bash
-ship status myapp
-ship logs myapp
-ship logs myapp --lines 100
-ship remove myapp
-```
-All return JSON with `{"status": "ok", ...}` or `{"status": "error", "code": "...", ...}`.
-## Error Codes
-Machine-readable. No guessing.
-| Code | Meaning |
-|------|---------|
-| `SSH_FAILED` | Can't connect to VPS |
-| `UPLOAD_FAILED` | File transfer failed |
-| `BUILD_FAILED` | Docker build or compile failed |
-| `DEPLOY_FAILED` | systemd/Caddy setup failed |
-| `HEALTH_CHECK_FAILED` | App not responding |
-| `NOT_FOUND` | App doesn't exist |
-| `CONFLICT` | Name already taken |
-## Auto-Detection
-Ship looks at the directory and figures out what to do:
-| Directory contains | Deploy type |
-|-------------------|-------------|
-| `Dockerfile` | Docker build → systemd service |
-| `index.html` | Static site → Caddy file_server |
-| Single executable | Binary → systemd service |
-| `go.mod` | Go build → systemd service |
-| `package.json` + no Dockerfile | Error: "Add a Dockerfile" |
-No config files. No `ship.json`. No `ship init`.
-## TTL (Time-To-Live)
-Agents create previews. Previews should auto-delete.
-```bash
-ship ./site --name pr-123 --ttl 1h
-ship ./site --name pr-123 --ttl 7d
-```
-After TTL expires, the deploy is removed automatically. The `expires` field in JSON tells you when.
-## Health Checks
-Every deploy is verified. Ship waits for the app to respond before returning success.
- Static sites: `GET /` returns 2xx
- Apps: `GET /` by default, or specify `--health /healthz`
- Timeout: 30s
- If health check fails: `{"status": "error", "code": "HEALTH_CHECK_FAILED", ...}`
-## Name Generation
-No name? Ship generates one.
-```bash
-ship ./site
-# {"name": "ship-a1b2c3", "url": "https://ship-a1b2c3.example.com", ...}
-```
-Provide a name to get a stable URL:
-```bash
-ship ./site --name docs
-# {"name": "docs", "url": "https://docs.example.com", ...}
-```
-## Host Setup
-One-time setup for a VPS:
-```bash
-ship host init user@my-vps.com --domain example.com
-```
-```json
-{
-  "status": "ok",
-  "host": "my-vps.com",
-  "domain": "example.com",
-  "installed": ["caddy", "docker", "systemd"]
-}
-```
-After this, the host is ready. Ship remembers it.
-## Human Output
-Humans are an afterthought, but they can use ship too:
-```bash
-ship ./site --pretty
-```
-```
-✓ Deployed to https://ship-a1b2c3.example.com (4.2s)
-```
-Or set globally:
-```bash
-export SHIP_PRETTY=1
-```
-## Implementation Phases
-### Phase 1: JSON Everything
- [ ] JSON output on all commands
- [ ] Structured error codes
- [ ] Exit codes match error states
-### Phase 2: Smart Deploys
- [ ] Auto-detect project type
- [ ] Health checks on every deploy
- [ ] `--ttl` with server-side cleanup
-### Phase 3: Zero Friction
- [ ] `ship ./dir` with no flags (auto name, auto detect)
- [ ] `ship host init` fully automated
- [ ] One binary, zero dependencies on client
-## Non-Goals
- **Pretty output** — That's what `--pretty` is for
- **Interactive prompts** — Never. Agents can't answer prompts.
- **Config files** — Zero config. Detect everything.
- **Plugin system** — Keep it simple.
- **Multi-cloud orchestration** — One VPS at a time.
-## Success Criteria
-Ship is done when an agent can:
-1. Build code
-2. Run `ship ./code`
-3. Parse the JSON response
-4. Use the URL
-No docs. No setup. No tokens. No accounts. Just `ship ./code`.

-# Ship v2 Technical Specification
-## Overview
-Ship deploys code to a VPS. Input: path to code. Output: JSON with URL.
-```bash
-ship ./myproject
-# {"status":"ok","name":"ship-a1b2c3","url":"https://ship-a1b2c3.example.com","type":"docker","took_ms":8200}
-```
-## CLI Interface
-### Primary Command
-```
-ship [PATH] [FLAGS]
-```
-**PATH**: File or directory to deploy. Defaults to `.` (current directory).
-**FLAGS**:
-| Flag | Type | Default | Description |
-|------|------|---------|-------------|
-| `--name` | string | auto-generated | Deploy name (becomes subdomain) |
-| `--host` | string | default host | VPS host (SSH config name or user@host) |
-| `--health` | string | `/` for static, none for apps | Health check endpoint |
-| `--ttl` | duration | none | Auto-delete after duration (e.g., `1h`, `7d`) |
-| `--env` | string[] | none | Environment variables (`KEY=VALUE`) |
-| `--env-file` | string | none | Path to .env file |
-| `--pretty` | bool | false | Human-readable output |
-### Other Commands
-```
-ship list [--host HOST]
-ship status NAME [--host HOST]
-ship logs NAME [--lines N] [--host HOST]
-ship remove NAME [--host HOST]
-ship host init USER@HOST --domain DOMAIN
-ship host status [--host HOST]
-```
-All commands output JSON unless `--pretty` is set.
-## Output Schema
-### Success Response
-```typescript
-{
-  status: "ok",
-  name: string,
-  url: string,
-  type: "static" | "docker" | "binary",
-  took_ms: number,
-  health?: {
-    endpoint: string,
-    status: number,
-    latency_ms: number
-  },
-  expires?: string  // ISO 8601, only if --ttl set
-}
-```
-### Error Response
-```typescript
-{
-  status: "error",
-  code: string,
-  message: string,
-  name?: string,
-  url?: string
-}
-```
-### Exit Codes
-| Code | Meaning |
-|------|---------|
-| 0 | Success |
-| 1 | Deploy failed |
-| 2 | Invalid arguments |
-| 3 | SSH connection failed |
-| 4 | Health check failed |
-## Error Codes
-| Code | Description |
-|------|-------------|
-| `INVALID_PATH` | Path doesn't exist or isn't readable |
-| `UNKNOWN_PROJECT_TYPE` | Can't detect how to deploy |
-| `SSH_CONNECT_FAILED` | Can't establish SSH connection |
-| `SSH_AUTH_FAILED` | SSH key rejected |
-| `UPLOAD_FAILED` | SCP/rsync failed |
-| `BUILD_FAILED` | Docker build or compilation failed |
-| `SERVICE_FAILED` | systemd unit failed to start |
-| `CADDY_FAILED` | Caddy reload failed |
-| `HEALTH_CHECK_FAILED` | App didn't respond in time |
-| `HEALTH_CHECK_TIMEOUT` | Health check timed out |
-| `NOT_FOUND` | Named deploy doesn't exist |
-| `CONFLICT` | Name already in use (if --no-update) |
-| `HOST_NOT_CONFIGURED` | No default host, --host required |
-| `INVALID_TTL` | Can't parse TTL duration |
-## Auto-Detection Logic
-When given a path, ship determines deploy type:
-```
-is_file(path)?
-  → is_executable(path)?
-    → BINARY
-    → ERROR: "Not an executable file"
-  
-is_directory(path)?
-  → has_file("Dockerfile")?
-    → DOCKER
-  → has_file("index.html") OR has_file("index.htm")?
-    → STATIC
-  → has_file("go.mod") AND NOT has_file("Dockerfile")?
-    → ERROR: "Go project without Dockerfile. Add a Dockerfile or build a binary."
-  → has_file("package.json") AND NOT has_file("Dockerfile")?
-    → ERROR: "Node project without Dockerfile. Add a Dockerfile."
-  → is_empty(path)?
-    → ERROR: "Directory is empty"
-  → ERROR: "Can't detect project type. Add a Dockerfile or index.html."
-```
-## Name Generation
-If `--name` not provided:
-```
-name = "ship-" + random_alphanumeric(6)
-```
-Names must match: `^[a-z0-9][a-z0-9-]{0,61}[a-z0-9]$`
-Invalid names return `INVALID_NAME` error.
-## Port Allocation
-Ports are allocated server-side.
-### Server Files
-```
-/etc/ship/ports/<name>     # Contains allocated port number
-```
-### Allocation Algorithm
-```python
-def allocate_port(name):
-    port_file = f"/etc/ship/ports/{name}"
-    
-    if exists(port_file):
-        return int(read(port_file))
-    
-    used_ports = [int(read(f)) for f in glob("/etc/ship/ports/*")]
-    next_port = 9000
-    while next_port in used_ports:
-        next_port += 1
-    
-    write(port_file, str(next_port))
-    return next_port
-```
-### Port Range
- Start: 9000
- Max: 9999
- Error if exhausted: `PORT_EXHAUSTED`
-## Server File Layout
-```
-/etc/ship/
-  ports/<name>              # Port allocation (contains port number)
-  env/<name>.env            # Environment variables
-  ttl/<name>                # TTL expiry timestamp (Unix epoch)
-/var/www/<name>/            # Static site files
-/var/lib/<name>/
-  src/                      # Docker build context (checked out source)
-  data/                     # Persistent data volume
-/etc/systemd/system/<name>.service    # systemd unit
-/etc/caddy/sites-enabled/<name>.caddy # Caddy config
-```
-## Deploy Flows
-### Static Site
-1. Validate path is directory with index.html
-2. Generate name if needed
-3. SSH: Create `/var/www/<name>/`
-4. rsync: Upload directory contents to `/var/www/<name>/`
-5. SSH: Set ownership to `www-data`
-6. Generate Caddyfile
-7. SSH: Write to `/etc/caddy/sites-enabled/<name>.caddy`
-8. SSH: Reload Caddy
-9. Health check: `GET https://<name>.<domain>/`
-10. If TTL: Write expiry to `/etc/ship/ttl/<name>`
-11. Return JSON
-### Docker
-1. Validate path is directory with Dockerfile
-2. Generate name if needed
-3. Allocate port (server-side)
-4. rsync: Upload directory to `/var/lib/<name>/src/`
-5. SSH: `docker build -t <name> /var/lib/<name>/src/`
-6. Generate systemd unit (runs `docker run`)
-7. SSH: Write to `/etc/systemd/system/<name>.service`
-8. SSH: Write env file to `/etc/ship/env/<name>.env`
-9. SSH: `systemctl daemon-reload && systemctl restart <name>`
-10. Generate Caddyfile (reverse proxy to port)
-11. SSH: Write to `/etc/caddy/sites-enabled/<name>.caddy`
-12. SSH: Reload Caddy
-13. Health check: `GET https://<name>.<domain><health_endpoint>`
-14. If TTL: Write expiry to `/etc/ship/ttl/<name>`
-15. Return JSON
-### Binary
-1. Validate path is executable file
-2. Generate name if needed
-3. Allocate port (server-side)
-4. SCP: Upload binary to `/usr/local/bin/<name>`
-5. SSH: `chmod +x /usr/local/bin/<name>`
-6. Generate systemd unit
-7. SSH: Write to `/etc/systemd/system/<name>.service`
-8. SSH: Write env file to `/etc/ship/env/<name>.env`
-9. SSH: `systemctl daemon-reload && systemctl restart <name>`
-10. Generate Caddyfile (reverse proxy to port)
-11. SSH: Write to `/etc/caddy/sites-enabled/<name>.caddy`
-12. SSH: Reload Caddy
-13. Health check: `GET https://<name>.<domain><health_endpoint>`
-14. If TTL: Write expiry to `/etc/ship/ttl/<name>`
-15. Return JSON
-## Health Checks
-### Behavior
-After deploy, verify the app is responding:
-1. Wait 2 seconds (let app start)
-2. `GET https://<name>.<domain><health_endpoint>`
-3. If 2xx or 3xx: success
-4. If error or timeout: retry after 2s
-5. Max retries: 15 (total 30s)
-6. If all retries fail: return `HEALTH_CHECK_FAILED`
-### Health Endpoint
-| Deploy Type | Default | Override |
-|-------------|---------|----------|
-| static | `/` | `--health` |
-| docker | none (skip) | `--health` |
-| binary | none (skip) | `--health` |
-When no health endpoint: skip health check, return success after service starts.
-## TTL (Auto-Expiry)
-### Setting TTL
-```bash
-ship ./site --name preview --ttl 24h
-```
-Supported formats: `30m`, `1h`, `24h`, `7d`
-### Server-Side Cleanup
-A systemd timer runs hourly:
-```ini
-# /etc/systemd/system/ship-cleanup.timer
-[Timer]
-OnCalendar=hourly
-Persistent=true
-# /etc/systemd/system/ship-cleanup.service
-[Service]
-Type=oneshot
-ExecStart=/usr/local/bin/ship-cleanup
-```
-Cleanup script:
-```bash
-#!/bin/bash
-now=$(date +%s)
-for f in /etc/ship/ttl/*; do
-  name=$(basename "$f")
-  expires=$(cat "$f")
-  if [ "$now" -gt "$expires" ]; then
-    ship remove "$name"
-  fi
-done
-```
-### TTL File Format
-```
-/etc/ship/ttl/<name>
-```
-Contents: Unix timestamp (seconds since epoch)
-## Templates
-### systemd Unit (Docker)
-```ini
-[Unit]
-Description=ship: {{.Name}}
-After=docker.service
-Requires=docker.service
-[Service]
-Restart=always

-```
-### Caddyfile (Reverse Proxy)
-```
-{{.Domain}} {
-    reverse_proxy localhost:{{.Port}}
-}
-```
-### Caddyfile (Static)
-```
-{{.Domain}} {
-    root * /var/www/{{.Name}}
-    file_server
-    encode gzip
-}
-```
-## Environment Variables
-Always set by ship:
-| Variable | Value |
-|----------|-------|
-| `PORT` | Allocated port number |
-| `SHIP_NAME` | Deploy name |
-| `SHIP_URL` | Full URL |
-User variables from `--env` or `--env-file` are merged.
-## Host Initialization
-```bash
-ship host init user@vps.example.com --domain example.com
-```
-### Steps
-1. SSH: Check connectivity
-2. SSH: Install packages (`apt install -y caddy docker.io`)
-3. SSH: Enable services (`systemctl enable --now caddy docker`)
-4. SSH: Create directories (`/etc/ship/ports`, `/etc/ship/env`, `/etc/ship/ttl`)
-5. SSH: Install cleanup timer
-6. SSH: Configure Caddy base
-7. Update local state with host info
-### Output
-```json
-{
-  "status": "ok",
-  "host": "vps.example.com",
-  "domain": "example.com",
-  "installed": ["caddy", "docker"]
-}
-```
-## Local State
-Stored at `~/.config/ship/state.json`:
-```json
-{
-  "default_host": "vps",
-  "hosts": {
-    "vps": {
-      "ssh": "user@vps.example.com",
-      "domain": "example.com"
-    }
-  }
-}
-```
-Local state is minimal — server is source of truth for ports, deploys, TTLs.
-## Pretty Output
-When `--pretty` is set (or `SHIP_PRETTY=1`):
-### Deploy Success
-```
-✓ Deployed to https://myapp.example.com (4.2s)
-```
-### Deploy Failure
-```
-✗ Deploy failed: health check timed out after 30s
-```
-### List
-```
-NAME          URL                              TYPE    STATUS
-api           https://api.example.com          docker  running
-preview-x7k   https://preview-x7k.example.com  static  running (expires in 23h)
-```
-## Implementation Notes
-### SSH Execution
-Use a single SSH connection with multiplexing:
-```bash
-ssh -o ControlMaster=auto -o ControlPath=/tmp/ship-%r@%h:%p -o ControlPersist=60 ...
-```
-### Concurrency
-Ship is not designed for concurrent deploys of the same name. Behavior is undefined.
-Different names can deploy concurrently.
-### Rollback (Future)
-Not in v2.0. Future consideration: keep last N versions, `ship rollback <name>`.

-## Appendix: Example Session
-```bash
-$ mkdir -p /tmp/hello && echo '<h1>Hello</h1>' > /tmp/hello/index.html
-$ ship /tmp/hello --name hello
-{"status":"ok","name":"hello","url":"https://hello.example.com","type":"static","took_ms":3200,"health":{"endpoint":"/","status":200,"latency_ms":45}}

2
3	Ship is a deployment tool built for AI agents.
4
5	Agents write code. Ship puts it on the internet. That's it.
6
7	## The Problem
8
9	AI agents can write code, but deploying it is a mess:
10	- Vercel/Railway/Fly require accounts, API tokens, platform-specific config
11	- Docker/K8s are overkill for "make this code accessible via URL"
12	- Most tools assume a human is reading the output
13
14	Agents need: code → URL. Nothing else.
15
16	## Ship's Approach
17
18	```bash
19	ship ./myproject
20	# {"status":"ok","url":"https://abc123.example.com","took_ms":4200}
21	```
22
23	That's the entire interface. Point ship at code, get a URL back as JSON.
24
25	### Core Principles
26
27	1. JSON in, JSON out — No human-formatted output. No spinners. No emoji. Agents parse JSON.
28
29	2. One command — No workflows. No "init then configure then deploy." One command does everything.
30
31	3. Verify or fail — Every deploy is health-checked. If the app isn't responding, ship returns an error. No silent failures.
32
33	4. Self-cleaning — Deploys can auto-expire. Agents create lots of previews; they shouldn't pile up forever.
34
35	5. Zero config — Point at a directory. Ship figures out if it's static, Docker, or a binary. No config files required.
36
37	6. SSH-only — No accounts. No API tokens. No vendor lock-in. Just SSH access to a VPS.

106	\| Code \| Meaning \|
107	\|------\|---------\|
108	\| `SSH_FAILED` \| Can't connect to VPS \|
109	\| `UPLOAD_FAILED` \| File transfer failed \|
110	\| `BUILD_FAILED` \| Docker build or compile failed \|
111	\| `DEPLOY_FAILED` \| systemd/Caddy setup failed \|
112	\| `HEALTH_CHECK_FAILED` \| App not responding \|
113	\| `NOT_FOUND` \| App doesn't exist \|
114	\| `CONFLICT` \| Name already taken \|
115
116	## Auto-Detection
117
118	Ship looks at the directory and figures out what to do:
119
120	\| Directory contains \| Deploy type \|
121	\|-------------------\|-------------\|
122	\| `Dockerfile` \| Docker build → systemd service \|
123	\| `index.html` \| Static site → Caddy file_server \|
124	\| Single executable \| Binary → systemd service \|
125	\| `go.mod` \| Go build → systemd service \|
126	\| `package.json` + no Dockerfile \| Error: "Add a Dockerfile" \|
127
128	No config files. No `ship.json`. No `ship init`.
129
130	## TTL (Time-To-Live)
131
132	Agents create previews. Previews should auto-delete.
133
134	```bash
135	ship ./site --name pr-123 --ttl 1h
136	ship ./site --name pr-123 --ttl 7d
137	```
138
139	After TTL expires, the deploy is removed automatically. The `expires` field in JSON tells you when.
140
141	## Health Checks
142
143	Every deploy is verified. Ship waits for the app to respond before returning success.
144
145	- Static sites: `GET /` returns 2xx
146	- Apps: `GET /` by default, or specify `--health /healthz`
147	- Timeout: 30s
148	- If health check fails: `{"status": "error", "code": "HEALTH_CHECK_FAILED", ...}`
149
150	## Name Generation
151
152	No name? Ship generates one.
153
154	```bash
155	ship ./site
156	# {"name": "ship-a1b2c3", "url": "https://ship-a1b2c3.example.com", ...}
157	```
158
159	Provide a name to get a stable URL:
160
161	```bash
162	ship ./site --name docs
163	# {"name": "docs", "url": "https://docs.example.com", ...}
164	```
165
166	## Host Setup
167
168	One-time setup for a VPS:
169
170	```bash
171	ship host init user@my-vps.com --domain example.com
172	```
173
174	```json
175	{
176	"status": "ok",
177	"host": "my-vps.com",
178	"domain": "example.com",
179	"installed": ["caddy", "docker", "systemd"]
180	}
181	```
182
183	After this, the host is ready. Ship remembers it.
184
185	## Human Output
186
187	Humans are an afterthought, but they can use ship too:
188
189	```bash
190	ship ./site --pretty
191	```
192
193	```
194	✓ Deployed to https://ship-a1b2c3.example.com (4.2s)
195	```
196
197	Or set globally:
198	```bash
199	export SHIP_PRETTY=1
200	```
201
202	## Implementation Phases
203
204	### Phase 1: JSON Everything
205	- [ ] JSON output on all commands
206	- [ ] Structured error codes
207	- [ ] Exit codes match error states
208
209	### Phase 2: Smart Deploys
210	- [ ] Auto-detect project type
211	- [ ] Health checks on every deploy
212	- [ ] `--ttl` with server-side cleanup
213
214	### Phase 3: Zero Friction
215	- [ ] `ship ./dir` with no flags (auto name, auto detect)
216	- [ ] `ship host init` fully automated
217	- [ ] One binary, zero dependencies on client
218
219	## Non-Goals
220
221	- Pretty output — That's what `--pretty` is for
222	- Interactive prompts — Never. Agents can't answer prompts.
223	- Config files — Zero config. Detect everything.
224	- Plugin system — Keep it simple.
225	- Multi-cloud orchestration — One VPS at a time.
226
227	## Success Criteria
228
229	Ship is done when an agent can:
230
231	1. Build code
232	2. Run `ship ./code`
233	3. Parse the JSON response
234	4. Use the URL
235
236	No docs. No setup. No tokens. No accounts. Just `ship ./code`.
237
238	---
239
240	Built for agents. Tolerated by humans.

1	# Ship v2 Technical Specification
2
3	## Overview
4
5	Ship deploys code to a VPS. Input: path to code. Output: JSON with URL.
6
7	```bash
8	ship ./myproject
9	# {"status":"ok","name":"ship-a1b2c3","url":"https://ship-a1b2c3.example.com","type":"docker","took_ms":8200}
10	```
11
12	## CLI Interface
13
14	### Primary Command
15
16	```
17	ship [PATH] [FLAGS]
18	```
19
20	PATH: File or directory to deploy. Defaults to `.` (current directory).

77
78	### Exit Codes
79
80	\| Code \| Meaning \|
81	\|------\|---------\|
82	\| 0 \| Success \|
83	\| 1 \| Deploy failed \|
84	\| 2 \| Invalid arguments \|
85	\| 3 \| SSH connection failed \|

87
88	## Error Codes
89
90	\| Code \| Description \|
91	\|------\|-------------\|
92	\| `INVALID_PATH` \| Path doesn't exist or isn't readable \|

104	\| `HOST_NOT_CONFIGURED` \| No default host, --host required \|
105	\| `INVALID_TTL` \| Can't parse TTL duration \|
106
107	## Auto-Detection Logic
108
109	When given a path, ship determines deploy type:
110
111	```
112	is_file(path)?
113	→ is_executable(path)?
114	→ BINARY
115	→ ERROR: "Not an executable file"
116
117	is_directory(path)?
118	→ has_file("Dockerfile")?
119	→ DOCKER
120	→ has_file("index.html") OR has_file("index.htm")?
121	→ STATIC
122	→ has_file("go.mod") AND NOT has_file("Dockerfile")?
123	→ ERROR: "Go project without Dockerfile. Add a Dockerfile or build a binary."
124	→ has_file("package.json") AND NOT has_file("Dockerfile")?
125	→ ERROR: "Node project without Dockerfile. Add a Dockerfile."
126	→ is_empty(path)?
127	→ ERROR: "Directory is empty"
128	→ ERROR: "Can't detect project type. Add a Dockerfile or index.html."
129	```
130
131	## Name Generation
132
133	If `--name` not provided:
134
135	```
136	name = "ship-" + random_alphanumeric(6)
137	```
138
139	Names must match: `^[a-z0-9][a-z0-9-]{0,61}[a-z0-9]$`
140
141	Invalid names return `INVALID_NAME` error.
142
143	## Port Allocation
144
145	Ports are allocated server-side.
146
147	### Server Files
148
149	```
150	/etc/ship/ports/<name> # Contains allocated port number
151	```
152
153	### Allocation Algorithm
154
155	```python
156	def allocate_port(name):
157	port_file = f"/etc/ship/ports/{name}"
158
159	if exists(port_file):
160	return int(read(port_file))
161
162	used_ports = [int(read(f)) for f in glob("/etc/ship/ports/*")]
163	next_port = 9000
164	while next_port in used_ports:
165	next_port += 1
166
167	write(port_file, str(next_port))
168	return next_port
169	```
170
171	### Port Range
172
173	- Start: 9000
174	- Max: 9999
175	- Error if exhausted: `PORT_EXHAUSTED`
176
177	## Server File Layout
178
179	```
180	/etc/ship/
181	ports/<name> # Port allocation (contains port number)
182	env/<name>.env # Environment variables
183	ttl/<name> # TTL expiry timestamp (Unix epoch)
184
185	/var/www/<name>/ # Static site files
186
187	/var/lib/<name>/
188	src/ # Docker build context (checked out source)
189	data/ # Persistent data volume
190
191	/etc/systemd/system/<name>.service # systemd unit
192	/etc/caddy/sites-enabled/<name>.caddy # Caddy config
193	```
194
195	## Deploy Flows
196
197	### Static Site
198
199	1. Validate path is directory with index.html
200	2. Generate name if needed
201	3. SSH: Create `/var/www/<name>/`

227	15. Return JSON
228
229	### Binary
230
231	1. Validate path is executable file
232	2. Generate name if needed
233	3. Allocate port (server-side)
234	4. SCP: Upload binary to `/usr/local/bin/<name>`

243	13. Health check: `GET https://<name>.<domain><health_endpoint>`
244	14. If TTL: Write expiry to `/etc/ship/ttl/<name>`
245	15. Return JSON
246
247	## Health Checks
248
249	### Behavior
250
251	After deploy, verify the app is responding:
252
253	1. Wait 2 seconds (let app start)
254	2. `GET https://<name>.<domain><health_endpoint>`
255	3. If 2xx or 3xx: success
256	4. If error or timeout: retry after 2s
257	5. Max retries: 15 (total 30s)
258	6. If all retries fail: return `HEALTH_CHECK_FAILED`
259
260	### Health Endpoint
261
262	\| Deploy Type \| Default \| Override \|
263	\|-------------\|---------\|----------\|
264	\| static \| `/` \| `--health` \|
265	\| docker \| none (skip) \| `--health` \|
266	\| binary \| none (skip) \| `--health` \|
267
268	When no health endpoint: skip health check, return success after service starts.
269
270	## TTL (Auto-Expiry)
271
272	### Setting TTL
273
274	```bash
275	ship ./site --name preview --ttl 24h
276	```
277
278	Supported formats: `30m`, `1h`, `24h`, `7d`
279
280	### Server-Side Cleanup
281
282	A systemd timer runs hourly:
283
284	```ini
285	# /etc/systemd/system/ship-cleanup.timer
286	[Timer]
287	OnCalendar=hourly
288	Persistent=true
289
290	# /etc/systemd/system/ship-cleanup.service
291	[Service]
292	Type=oneshot
293	ExecStart=/usr/local/bin/ship-cleanup
294	```
295
296	Cleanup script:
297
298	```bash
299	#!/bin/bash
300	now=$(date +%s)
301	for f in /etc/ship/ttl/*; do
302	name=$(basename "$f")
303	expires=$(cat "$f")
304	if [ "$now" -gt "$expires" ]; then
305	ship remove "$name"
306	fi
307	done
308	```
309
310	### TTL File Format
311
312	```
313	/etc/ship/ttl/<name>
314	```
315
316	Contents: Unix timestamp (seconds since epoch)
317

379	encode gzip
380	}
381	```
382
383	## Environment Variables
384
385	Always set by ship:
386
387	\| Variable \| Value \|
388	\|----------\|-------\|
389	\| `PORT` \| Allocated port number \|
390	\| `SHIP_NAME` \| Deploy name \|
391	\| `SHIP_URL` \| Full URL \|
392
393	User variables from `--env` or `--env-file` are merged.
394
395	## Host Initialization
396
397	```bash
398	ship host init user@vps.example.com --domain example.com
399	```
400
401	### Steps
402
403	1. SSH: Check connectivity
404	2. SSH: Install packages (`apt install -y caddy docker.io`)
405	3. SSH: Enable services (`systemctl enable --now caddy docker`)
406	4. SSH: Create directories (`/etc/ship/ports`, `/etc/ship/env`, `/etc/ship/ttl`)
407	5. SSH: Install cleanup timer
408	6. SSH: Configure Caddy base
409	7. Update local state with host info
410
411	### Output
412
413	```json
414	{
415	"status": "ok",
416	"host": "vps.example.com",
417	"domain": "example.com",
418	"installed": ["caddy", "docker"]
419	}
420	```
421
422	## Local State
423
424	Stored at `~/.config/ship/state.json`:
425
426	```json
427	{
428	"default_host": "vps",
429	"hosts": {
430	"vps": {
431	"ssh": "user@vps.example.com",
432	"domain": "example.com"
433	}
434	}
435	}
436	```
437
438	Local state is minimal — server is source of truth for ports, deploys, TTLs.
439
440	## Pretty Output
441
442	When `--pretty` is set (or `SHIP_PRETTY=1`):
443
444	### Deploy Success
445
446	```
447	✓ Deployed to https://myapp.example.com (4.2s)
448	```
449
450	### Deploy Failure
451
452	```
453	✗ Deploy failed: health check timed out after 30s
454	```
455
456	### List
457
458	```
459	NAME URL TYPE STATUS
460	api https://api.example.com docker running
461	preview-x7k https://preview-x7k.example.com static running (expires in 23h)
462	```
463
464	## Implementation Notes
465
466	### SSH Execution
467
468	Use a single SSH connection with multiplexing:
469
470	```bash
471	ssh -o ControlMaster=auto -o ControlPath=/tmp/ship-%r@%h:%p -o ControlPersist=60 ...
472	```
473
474	### Concurrency
475
476	Ship is not designed for concurrent deploys of the same name. Behavior is undefined.
477
478	Different names can deploy concurrently.
479
480	### Rollback (Future)
481
482	Not in v2.0. Future consideration: keep last N versions, `ship rollback <name>`.
