What is a Homelab?

A homelab is a private server setup that runs on your home network. It can host various services and applications like:

• Pi-hole: To block ads and trackers.

• Nextcloud: Your personal cloud storage solution.

• Jellyfin: A media server for streaming your movies and shows.

A homelab gives you complete control over your data while providing a fun and educational way to tinker with technology. You can even assign a custom domain name to your homelab for easy access from anywhere.

Recommended Setup:

• A dedicated old PC, laptop, or Raspberry Pi.

• Familiarity with basic Linux commands and file systems.

Downloading Docker

To get started, you need to install Docker:

1. Choose Your OS:
   Docker works on Windows, macOS, and Linux. Visit Docker's official website and select the version compatible with your operating system.

2. Download & Install:
   Follow the prompts to download and install Docker.

   • On Windows, you may need to enable WSL2 for better performance.

   • On macOS, Docker Desktop is the preferred option.

3. Verify Installation:
   Run the command:

   docker --version

   This will display the installed Docker version, confirming a successful installation.

4. Rootless Mode (Optional):
   For enhanced security, consider running Docker in rootless mode. This allows you to manage containers without requiring root privileges.

Pro Tip: Refer to Docker’s official documentation for troubleshooting and the latest updates.

1. Nextcloud: Your Personal Google Drive

If you’re tired of running out of storage on Google Drive or paying for subscriptions, Nextcloud is your answer. It’s an open-source alternative to Google Workspace that you can host yourself.

Features of Nextcloud:

• File storage and sharing.

• Office integration for documents.

• Video calls with Nextcloud Talk.

• Antivirus scanning with ClamAV.

• Advanced search capabilities.

Why Use It?
Instead of spending $20/year on Google subscriptions, invest in a hard drive for long-term storage. Nextcloud ensures your data is private and accessible anytime.

Setup Resources:

• Official Setup Guide.

2. Jellyfin: Your Own Media Server

Do you have a collection of movies, music, or personal videos that you want to stream across devices? With Jellyfin, you can turn your homelab into a media server accessible from anywhere.

Why Use Jellyfin?

Setup:
Use a preconfigured Docker image to get Jellyfin up and running. Here’s a detailed installation guide.

Pro Tip: Use LinuxServer.io’s Docker images for optimized configurations.

3. Affine or Obsidian: Host Your Own Note-Taking App

If you want secure, ad-free, and free access to your notes across devices, host your own note-taking app.

Top Options:

• Affine: A Notion-like interface that stores data in a database.

• Obsidian: Stores notes as Markdown files, making backups easy and setup simple.

Why Use It?

• Avoid giving your data to companies that sell it or use it for AI training.

• Access notes on any device via a browser.

Setup:

• Affine Setup Guide.

• Obsidian Tutorials.

Pro Tip: Obsidian has a steeper learning curve but offers unparalleled customization for power users.

4. Locally Hosted AI Models

Did you know you can run AI models like ChatGPT locally on your computer? It’s a lifesaver when internet access is unreliable or OpenAI’s servers are down.

Setup Requirements:

• Linux OS (Debian, Ubuntu, or WSL on Windows).

Usage:

• Host the AI model locally and integrate it with tools like VSCode using the Continue plugin.

• Ideal for offline coding assistance and natural language processing tasks.

Pro Tip: Check out YouTube tutorials by Wolfgang’s Channel for a hands-on walkthrough.

5. Pi-hole: Block Ads and Trackers

If slow internet or intrusive ads are a concern, Pi-hole can help. It acts as a DNS server that filters out ads and trackers before they reach your devices.

Benefits:

• Faster browsing speeds.

• Blocks annoying ads on all devices in your network.

• Ability to blacklist specific domains.

Setup:
Install Pi-hole on a Raspberry Pi or any always-on device. Learn more here.

Pro Tip: Combine Pi-hole with a DNS server like Cloudflare for maximum efficiency.

6. Run Virtual Machines

Docker can run lightweight virtual machines that you can access over your network. This is particularly useful for running isolated environments like Kali Linux or testing other operating systems.

Why It’s Cool:
Access these virtual machines from any device connected to your private network.

Setup:
Use prebuilt Docker images for popular VMs. Example: Kali Linux Image.

7. LibreOffice: Microsoft Office Alternative

If Microsoft Office is too pricey, try LibreOffice. It’s an open-source office suite that includes everything from a word processor to spreadsheets.

Why Use LibreOffice?

• Free and powerful alternative to MS Office.

• Runs locally without requiring an internet connection.

Setup:
Use a Docker image or download the standalone version from LibreOffice.

8. Danger Zone: Scan Files in a Sandbox

Have you ever hesitated to open a suspicious file? Danger Zone lets you scan files in a sandboxed environment, ensuring your computer stays safe.

Use Cases:

• Open PDFs and other files safely.

• Great for testing files downloaded from untrusted sources.

Setup:
Install Danger Zone via Docker for additional security layers. Installation guide here.

Conclusion

Docker truly revolutionizes the way we think about setting up and managing homelabs. By offering a simple, flexible, and scalable way to deploy applications, Docker allows you to create an environment tailored to your specific needs—whether you're hosting a personal cloud, experimenting with AI models, or running virtual machines for various use cases.

With Docker's containerization technology, you don’t have to worry about compatibility issues or complex configurations. It ensures that applications run consistently across different environments, making your homelab more reliable and secure. Plus, Docker’s ability to efficiently isolate each service in its container means you can easily experiment and try out new ideas without risking the stability of your entire system.

The best part is that Docker opens doors to a range of possibilities—no matter your level of expertise. Whether you’re a beginner just starting your homelab journey or an experienced tech enthusiast exploring advanced use cases, Docker offers the tools to enhance your home server setup.
