Scope

This skill covers the software layer — what runs inside a machine. For infrastructure (provisioning VMs, SSH hardening, firewalls, backups), use the

vps

skill.

When to Use

Configuring nginx, Caddy, or Apache
Deploying Node.js, Python, Go, or other apps
Docker and Docker Compose setups
SSL/TLS certificates with Let's Encrypt
Reverse proxy and load balancing
Process management (pm2, systemd services)
Troubleshooting port conflicts, CORS, connection errors
Self-hosting (Plex, Nextcloud, game servers)
Local development servers (Vite, webpack-dev-server)

Common Pitfalls

Port already in use — Check with
```
lsof -i :PORT
```
or
```
ss -tlnp | grep PORT
```
, kill stale processes
CORS in development — Proxy through your dev server or configure backend headers, don't disable in production
SSL certificate issues — Certbot needs port 80/443 open, use
```
--standalone
```
or
```
--webroot
```
mode appropriately
nginx config not loading — Always run
```
nginx -t
```
before
```
systemctl reload nginx
```
Docker container can't reach host — Use
```
host.docker.internal
```
(Docker Desktop) or
```
172.17.0.1
```
(Linux)
Process dies after SSH disconnect — Use systemd, pm2, or run inside tmux/screen
Wrong permissions on mounted volumes — Match container user UID with host file ownership

Patterns by Use Case

Use Case	Recommended Stack
Static site	Caddy (auto-SSL, zero config)
Node.js app	PM2 + nginx reverse proxy
Python (Django/FastAPI)	Gunicorn + nginx
Multiple services	Docker Compose + Traefik
Game server	Dedicated container + port mapping

Debugging Checklist

Is the process running?
```
systemctl status
```
or
```
docker ps
```
Is it listening?
```
ss -tlnp | grep PORT
```
Can you reach it locally?
```
curl localhost:PORT
```
Firewall blocking? Check
```
ufw status
```
or cloud security groups
Reverse proxy misconfigured? Check nginx logs:
```
/var/log/nginx/error.log
```
DNS pointing correctly?
```
dig domain.com
```
or
```
nslookup
```
