Two Paths to Homelab
When setting up a homelab server, you have a fundamental choice: install a hypervisor like Proxmox and run VMs/containers, or install a Linux distro and run Docker directly. Both approaches work, but they suit different needs.
Option 1: Bare-Metal Docker
Install Ubuntu/Debian directly on your hardware and run Docker containers.
Pros:
- Simple: One OS, one layer, easy to understand
- Efficient: No virtualization overhead
- Less RAM: No hypervisor consuming resources
- Quick setup: Running containers in 30 minutes
Cons:
- Single point of failure: OS issues affect everything
- Less flexible: Harder to try different OS/configurations
- Backup complexity: Full system backups are harder
Option 2: Proxmox Hypervisor
Install Proxmox VE and run virtual machines and LXC containers.
Pros:
- Isolation: VMs are completely separate
- Snapshots: Roll back any VM instantly
- Flexibility: Run different OSes, experiment freely
- Web GUI: Manage everything from browser
- Live migration: Move VMs between hosts
Cons:
- Learning curve: More concepts to understand
- Resource overhead: Each VM needs dedicated RAM
- Complexity: More moving parts
LXC Containers: The Middle Ground
Proxmox also supports LXC containers - lighter than VMs but with more isolation than Docker:
- Near-native performance
- Lower RAM overhead than VMs
- Full OS experience in each container
- Snapshots and backups
Recommended Approach for Beginners
Start with Bare-Metal Docker if:
- You have limited resources (8GB RAM or less)
- You want the fastest path to running services
- You're new to Linux and want to learn one thing at a time
- Your main goal is running Docker containers
Start with Proxmox if:
- You have 16GB+ RAM to spare
- You want to experiment with different setups
- You value snapshots and easy rollbacks
- You might run non-Docker workloads (Windows, specialized OS)
The Evolution Path
Many homelabbers evolve their setup:
- Start with bare-metal Docker
- Learn containers and services
- Upgrade hardware
- Migrate to Proxmox with a Docker VM/LXC
- Add specialized VMs as needed
There's no wrong answer - both paths lead to a functional homelab. Pick what matches your current resources and comfort level.
