Setup Homelab dengan Proxmox dan Docker

Homelab adalah cara terbaik untuk belajar dan experiment dengan teknologi enterprise tanpa kos yang tinggi.

Kenapa Homelab?

Dengan homelab, kita boleh:

• Belajar virtualization — Proxmox, VMware, Hyper-V
• Test deployment — Sebelum deploy ke production
• Self-host services — Media server, NAS, web apps
• Improve skills — Hands-on experience dengan real hardware

Hardware Setup

Untuk homelab yang cost-effective:

Component	Recommendation
CPU	Intel i5/i7 atau AMD Ryzen (min 4 cores)
RAM	32GB recommended (boleh start 16GB)
Storage	SSD untuk OS, HDD untuk data
Network	Gigabit ethernet

Tip: Mini PC lebih jimat elektrik berbanding tower server. Dell OptiPlex atau HP EliteDesk secondhand adalah pilihan bagus.

Proxmox VE Installation

Step 1: Download & Install

1. Muat turun ISO dari proxmox.com
2. Create bootable USB
3. Boot dan install

Step 2: Post-Install Configuration

# Remove subscription nag
sed -i.bak "s/data.status !== 'Active'/false/g" \
  /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js

# Add no-subscription repo
echo "deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription" \
  > /etc/apt/sources.list.d/pve-no-subscription.list

# Update system
apt update && apt upgrade -y

Docker dalam LXC Container

Untuk Docker, saya prefer guna LXC container berbanding VM — lebih lightweight.

Create LXC Container

Settings yang diperlukan:

• Memory: 4GB+
• Disk: 50GB+
• Features: Nesting enabled

Enable Docker Support

Edit container config di Proxmox host:

# /etc/pve/lxc/<CTID>.conf
features: nesting=1
lxc.apparmor.profile: unconfined
lxc.cgroup2.devices.allow: a
lxc.cap.drop:

Install Docker

# Install Docker
curl -fsSL https://get.docker.com | sh

# Add user to docker group
usermod -aG docker $USER

# Install Docker Compose
apt install docker-compose-plugin -y

Tips & Best Practices

1. Backup regularly — Guna Proxmox Backup Server
2. Use static IPs — Elak IP conflict
3. Monitor resources — Proxmox built-in atau Grafana
4. Document everything — Apa yang install dan configure
5. Separate networks — VLAN untuk management vs services

Kesimpulan

Homelab dengan Proxmox dan Docker adalah kombinasi yang powerful. Start small, experiment banyak, dan expand bila perlu.
