How It Works

1. PRE-FLIGHT CHECKS
   - Test SSH connection
   - Check disk space
   - Verify required runtimes (.NET/Node.js)
   - Validate DNS records

2. BUILD (Local)
   - npm run build (frontend)
   - dotnet publish / npm build (each service)

3. BACKUP
   - Create timestamped backup of current deployment

4. UPLOAD
   - Upload files via SFTP to new deploy directory
   - Upload additional paths (with exclude support)
   - For Node.js: runs npm install on VPS

5. CONFIGURE
   - Generate Caddy config (reverse proxy + HTTPS)
   - Generate systemd service per backend service

6. ACTIVATE
   - Update current symlink to new deploy
   - Restart services
   - Verify services stay running (3s stability check)
   - Reload Caddy

7. HEALTH CHECK
   - Verify each service responds via localhost
   - Rollback automatically if any check fails

VPS Directory Structure

After deployment, your VPS has this structure:

/var/www/{project}/
  ├── current/           -> symlink to deploys/{timestamp}
  ├── deploys/
  │   └── 20240115-143052/
  │       ├── frontend/
  │       ├── api/
  │       └── notifications/
  ├── backups/
  │   └── 20240115-140000/
  └── .shiphound/

Health Checks

After deployment, ShipHound verifies your app is running by sending HTTP requests to each service via SSH (curl on localhost). A response with status code 200-399 is considered healthy. If health checks fail, ShipHound automatically rolls back to the previous deployment.

By default, ShipHound checks the root path (/). Most APIs don't serve anything at /, which causes a false failure. You should either:

Set a healthCheckPath that returns a 200 response:

backend:
  path: ./backend
  port: 5000
  domain: api.myapp.com
  healthCheckPath: /health

Skip health checks if your app has no health endpoint:

shiphound deploy --skip-health-check

The service stability check (verifies the process stays running via systemd) always runs regardless of the --skip-health-check flag.

Health check behavior:

Waits 2 seconds after service start before first check
Retries up to 3 times with exponential backoff
Shows which URL is being checked and the attempt number
On failure, shows the HTTP status code returned
Automatically rolls back on failure

VPS Requirements

Ubuntu 22.04+ or Debian 11+
SSH access with key authentication
Passwordless sudo configured

To enable passwordless sudo:

ssh your-user@your-vps
echo "$USER ALL=(ALL) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/$USER

Everything else (Caddy, .NET, Node.js) is installed automatically by shiphound setup.

Troubleshooting

SSH Connection Failed

# Test SSH manually
ssh -i ~/.ssh/id_rsa deploy@your-vps-ip

# Check SSH key permissions (Linux/Mac)
chmod 600 ~/.ssh/id_rsa

Backend Won't Start

# Check service logs
shiphound logs --service api

# Or SSH and check directly
ssh deploy@your-vps
sudo journalctl -u my-app-api -f

Caddy/HTTPS Issues

# Check Caddy logs
shiphound logs --service caddy

# Verify DNS points to your VPS
nslookup yourdomain.com

Deployment Failed

ShipHound automatically rolls back on failure. Check the error message and logs:

shiphound diagnose
shiphound logs
shiphound debug

Service Crash-Looping

If a service starts but crashes immediately, ShipHound detects this during the stability check and shows the last 15 lines of logs. Common causes:

Missing environment variables
Wrong port configuration
Database connection issues
Missing dependencies

Wrong .NET / Node.js Version

If your app targets a different runtime version than what's installed on the VPS:

dotnetVersion: "9.0"
nodeVersion: "22"

Then run shiphound setup again to install the correct version. Preflight checks will block deploys if the required version isn't found.

Health Check Fails But App Is Running

If the stability check passes but health check fails, your app is running but not responding on the checked path. By default ShipHound checks / which many APIs don't serve.

Fix: Set healthCheckPath to an endpoint that returns HTTP 200, or use --skip-health-check.

Environment Variables Not Working

YAML has special characters that can break parsing. If your env values contain quotes, colons, or special characters, use single quotes:

env:
  # BAD - nested double quotes break YAML:
  ConnectionStrings__Default: "Host=localhost;Password="secret""

  # GOOD - single quotes handle inner quotes:
  ConnectionStrings__Default: 'Host=localhost;Password="secret"'

Check the generated service file on your VPS:

cat /etc/systemd/system/{project}-{service}.service

FAQ

Q: What backend frameworks are supported? A: .NET and Node.js/Express. Set type: node for Node.js backends.

Q: Can I deploy multiple services? A: Yes. Use the services: config instead of backend: to define multiple named services, each with their own port, domain, and runtime type.

Q: Do I need Docker? A: No. ShipHound deploys apps natively on Linux using systemd and Caddy.

Q: How does Node.js deployment work? A: ShipHound uploads your code (excluding node_modules), runs npm install --production on the VPS, and creates a systemd service.

Q: Will my app restart if it crashes? A: Yes. The systemd service is configured with Restart=always and starts on boot.

Q: What happens if deployment fails? A: ShipHound automatically restores your previous version from the backup directory.

Q: Can services share a domain? A: Yes. Use domainPath on services to route different URL paths to different services on the same domain.

Q: Can I deploy extra files like templates or seed data? A: Yes. Use additionalPaths to deploy any extra files or directories alongside your app, with optional exclude patterns.

Q: What VPS providers work with ShipHound? A: Any provider that gives you a Linux VPS with SSH access: DigitalOcean, Hetzner, Linode, Vultr, AWS Lightsail, etc.

Q: Can I use ShipHound with a monorepo? A: Yes. Point frontend.path and each service path to the correct subdirectory within your repo.

How It Works

1. PRE-FLIGHT CHECKS
   - Test SSH connection
   - Check disk space
   - Verify required runtimes (.NET/Node.js)
   - Validate DNS records

2. BUILD (Local)
   - npm run build (frontend)
   - dotnet publish / npm build (each service)

3. BACKUP
   - Create timestamped backup of current deployment

4. UPLOAD
   - Upload files via SFTP to new deploy directory
   - Upload additional paths (with exclude support)
   - For Node.js: runs npm install on VPS

5. CONFIGURE
   - Generate Caddy config (reverse proxy + HTTPS)
   - Generate systemd service per backend service

6. ACTIVATE
   - Update current symlink to new deploy
   - Restart services
   - Verify services stay running (3s stability check)
   - Reload Caddy

7. HEALTH CHECK
   - Verify each service responds via localhost
   - Rollback automatically if any check fails

VPS Directory Structure

After deployment, your VPS has this structure:

/var/www/{project}/
  ├── current/           -> symlink to deploys/{timestamp}
  ├── deploys/
  │   └── 20240115-143052/
  │       ├── frontend/
  │       ├── api/
  │       └── notifications/
  ├── backups/
  │   └── 20240115-140000/
  └── .shiphound/

Health Checks

By default, ShipHound checks the root path (/). Most APIs don't serve anything at /, which causes a false failure. You should either:

Set a healthCheckPath that returns a 200 response:

backend:
  path: ./backend
  port: 5000
  domain: api.myapp.com
  healthCheckPath: /health

Skip health checks if your app has no health endpoint:

shiphound deploy --skip-health-check

The service stability check (verifies the process stays running via systemd) always runs regardless of the --skip-health-check flag.

Health check behavior:

Waits 2 seconds after service start before first check
Retries up to 3 times with exponential backoff
Shows which URL is being checked and the attempt number
On failure, shows the HTTP status code returned
Automatically rolls back on failure

VPS Requirements

Ubuntu 22.04+ or Debian 11+
SSH access with key authentication
Passwordless sudo configured

To enable passwordless sudo:

ssh your-user@your-vps
echo "$USER ALL=(ALL) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/$USER

Everything else (Caddy, .NET, Node.js) is installed automatically by shiphound setup.

Troubleshooting

SSH Connection Failed

# Test SSH manually
ssh -i ~/.ssh/id_rsa deploy@your-vps-ip

# Check SSH key permissions (Linux/Mac)
chmod 600 ~/.ssh/id_rsa

Backend Won't Start

# Check service logs
shiphound logs --service api

# Or SSH and check directly
ssh deploy@your-vps
sudo journalctl -u my-app-api -f

Caddy/HTTPS Issues

# Check Caddy logs
shiphound logs --service caddy

# Verify DNS points to your VPS
nslookup yourdomain.com

Deployment Failed

ShipHound automatically rolls back on failure. Check the error message and logs:

shiphound diagnose
shiphound logs
shiphound debug

Service Crash-Looping

If a service starts but crashes immediately, ShipHound detects this during the stability check and shows the last 15 lines of logs. Common causes:

Missing environment variables
Wrong port configuration
Database connection issues
Missing dependencies

Wrong .NET / Node.js Version

If your app targets a different runtime version than what's installed on the VPS:

dotnetVersion: "9.0"
nodeVersion: "22"

Then run shiphound setup again to install the correct version. Preflight checks will block deploys if the required version isn't found.

Health Check Fails But App Is Running

If the stability check passes but health check fails, your app is running but not responding on the checked path. By default ShipHound checks / which many APIs don't serve.

Fix: Set healthCheckPath to an endpoint that returns HTTP 200, or use --skip-health-check.

Environment Variables Not Working

YAML has special characters that can break parsing. If your env values contain quotes, colons, or special characters, use single quotes:

env:
  # BAD - nested double quotes break YAML:
  ConnectionStrings__Default: "Host=localhost;Password="secret""

  # GOOD - single quotes handle inner quotes:
  ConnectionStrings__Default: 'Host=localhost;Password="secret"'
