Want to build your own AI agents at home? This step-by-step n8n tutorial shows you how to create powerful automation workflows and AI agents inside your homelab environment. Learn how to install n8n using Docker, connect AI models like OpenAI or local LLMs, automate tasks, and build intelligent workflows without advanced coding skills. Let's get n8n running, from routine tasks to workflows I didn’t expect to work this well!! I deployed n8n on Hostinger on a Ubuntu Linux server using Docker, Setup Hostinger here - https://www.hostinger.com/EMILIO Ensure you use Coupon Code EMILIO High-Level Setup Overview - use ChatGPT to help you with the commands. - Ubuntu Linux (Hostinger) - Docker - n8n Update Ubuntu to the latest version sudo apt update && sudo apt upgrade -y sudo reboot Install required base packages sudo apt install -y \ ca-certificates \ curl \ gnupg \ lsb-release Install Docker sudo apt install -y docker.io sudo systemctl enable docker sudo systemctl start docker docker --version Install Docker Compose sudo apt install -y docker-compose docker-compose --version Create working directory for n8n mkdir -p ~/n8n cd ~/n8n Create Docker Compose file nano docker-compose.yml Paste the following: version: "3.8" services: mysql: image: mysql:8.0 container_name: n8n-mysql restart: unless-stopped environment: MYSQL_ROOT_PASSWORD: strongrootpassword MYSQL_DATABASE: n8n MYSQL_USER: n8n MYSQL_PASSWORD: strongpassword volumes: - mysql_data:/var/lib/mysql n8n: image: n8nio/n8n:latest container_name: n8n restart: unless-stopped ports: - "5678:5678" environment: DB_TYPE: mysqldb DB_MYSQLDB_HOST: mysql DB_MYSQLDB_PORT: 3306 DB_MYSQLDB_DATABASE: n8n DB_MYSQLDB_USER: n8n DB_MYSQLDB_PASSWORD: strongpassword N8N_BASIC_AUTH_ACTIVE: "true" N8N_BASIC_AUTH_USER: admin N8N_BASIC_AUTH_PASSWORD: adminpassword depends_on: - mysql volumes: - n8n_data:/home/node/.n8n volumes: mysql_data: n8n_data: Save Start MySQL and n8n docker-compose up -d Access n8n in your browser http://YOUR_SERVER_IP:5678 STUFF I RECOMMEND ➤ My NAS | Synology DS1621+ - https://amzn.to/3xUl5Wi ➤ My Networking | Ubiquiti - https://amzn.to/4nrX7pg ➤ My Mini PC | Zimablade - https://amzn.to/43IqSuZ ➤ My Hard Drives | WD 26TB - https://amzn.to/4onIlRR ✖️ https://x.com/emilio_tech 🎓 MY TRAINING COURSES 🎓 https://bit.ly/emilio-training My popular courses - ➤ Become an IT Manager - https://bit.ly/TechToManager ➤ Master Cybersecurity - https://bit.ly/cyberemilio ➤ QNAP NAS Administration - https://bit.ly/qnaptraining ➤ Master the Synology NAS - https://bit.ly/LearnSynology ➤ Become a VMware Expert - https://bit.ly/vmware8training ➤ Learn Windows Server 2022 - https://bit.ly/server-2022 WHAT I USE - ➤ Intel NUC Mini PC - https://amzn.to/3VJuer9 ➤ Ubiquiti WiFi - https://amzn.to/3X0fR4x ➤ Raspberry Pi - https://amzn.to/4oJEtuf ➤ Server Rack Mini | DeskPi - https://amzn.to/4nHpNLq ➤ Protectli Vault | Mini PC - https://amzn.to/3JmDD7N ➤ NAS 6-Bay | Synology DS1621+ - https://amzn.to/3xUl5Wi ➤ NAS Rack | QNAP Rack - https://amzn.to/44frTdb ➤ 34" Curved Wide Monitor - https://amzn.to/4aL6zyF ➤ Digital Camera | Sony A7C - https://amzn.to/3VVt4KB ➤ Shure SM7B Mic - https://amzn.to/3MjPRgc ➤ Speakers | Presonus XT - https://amzn.to/49XH2RH 👉 Full List of my Gear: https://www.amazon.com/shop/techwithemilio 🔔 If you love tech, you don't want to miss the latest tech updates!

About This Video

I let AI take over my homelab, and honestly… it’s amazing. In this video I walk you step-by-step through getting n8n up and running in a way that actually makes sense, so you can start connecting “all the things” (cloud services, on-prem hardware, software, and APIs) and then layer AI on top. The goal is simple: stop doing repetitive admin work manually and start building workflows that trigger automatically—"when this happens, do this"—with AI doing the heavy lifting in the middle. I deploy n8n on an Ubuntu VPS (Hostinger) using Docker and Docker Compose, then I show a real workflow I use: a daily Synology NAS health check. I connect to my NAS over SSH, run commands like uptime and df -h (plus a bigger command dump), and then feed that raw output into OpenAI so it returns a clean, concise, technical summary—NAS name, model, last reboot, load, memory, and an overall health readout. Finally, I wire it into email (SMTP/Gmail) and schedule it to run every day at 8:00 a.m. Once you see this working, you’ll realize how quickly you can extend it to stuff like smarter CCTV alerts and weather-driven sprinkler automation.
