Proxmox Cloud Image Tool

Tool untuk membuat template di Proxmox menggunakan cloud image (Ubuntu, Debian, CentOS, dll) dengan Golang.

Features

• Download cloud image dari URL
• Customize image (resize disk, inject SSH key)
• Otomatis create template di Proxmox
• Support konfigurasi via CLI flags atau YAML file
• Progress bar untuk download
• QEMU Guest Agent support (auto-enable)
• Firewall configuration (enable/disable + custom rules)
• Batch mode untuk create multiple templates sekaligus

Requirements

• Go 1.19+
• SSH access ke Proxmox host
• qemu-img dan virt-customize (libguestfs-tools)

Install dependencies di Ubuntu/Debian:

sudo apt install qemu-utils libguestfs-tools

Installation

Quick Install (Recommended):

git clone <repo-url>
cd cloud-image
sudo ./install.sh

Installer akan otomatis:

• Install dependencies (qemu-utils, libguestfs-tools)
• Build binary
• Install ke /usr/local/bin

Manual Build:

git clone <repo-url>
cd cloud-image
go build -o proxmox-cloud-image
sudo cp proxmox-cloud-image /usr/local/bin/
sudo chmod +x /usr/local/bin/proxmox-cloud-image

Uninstall:

cd cloud-image
sudo ./uninstall.sh

Setelah install, bisa langsung dipanggil dari mana aja:

proxmox-cloud-image -h

Usage

Menggunakan CLI flags:

proxmox-cloud-image \
  -image-url "https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img" \
  -vm-name "ubuntu-template" \
  -vm-id 9000 \
  -proxmox-host "192.168.1.100" \
  -proxmox-user "root@pam" \
  -storage "local-lvm" \
  -memory 2048 \
  -cores 2 \
  -disk-size "20G" \
  -bridge "vmbr0" \
  -ssh-key "/root/.ssh/id_rsa.pub" \
  -guest-agent \
  -firewall

Auto-find VM ID (mulai dari 10000):

proxmox-cloud-image \
  -image-url "https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img" \
  -vm-name "ubuntu-template" \
  -proxmox-host "192.168.1.100" \
  -guest-agent

Dengan VLAN:

proxmox-cloud-image \
  -image-url "https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img" \
  -vm-name "ubuntu-template" \
  -vm-id 9000 \
  -proxmox-host "192.168.1.100" \
  -bridge "vmbr0" \
  -vlan-tag 100 \
  -guest-agent \
  -firewall

Menggunakan config file:

proxmox-cloud-image -config config.yaml

Contoh config.yaml:

image_url: "https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img"
vm_name: "ubuntu-template"
vm_id: 0
storage: "local-lvm"
memory: 2048
cores: 2
disk_size: "20G"
bridge: "vmbr0"
vlan_tag: 100
ssh_key: "/root/.ssh/id_rsa.pub"
proxmox_host: "192.168.1.100"
proxmox_user: "root@pam"
proxmox_pass: ""
guest_agent: true
firewall: true
firewall_rules:
  - type: in
    action: accept
    protocol: tcp
    dport: "22"
    comment: "SSH"
  - type: in
    action: accept
    protocol: tcp
    dport: "80,443"
    comment: "HTTP/HTTPS"

Batch mode (multiple templates):

Buat file batch (contoh: batch.txt) dengan list config files:

# Ubuntu templates
configs/ubuntu-22.04.yaml
configs/ubuntu-20.04.yaml

# Debian templates
configs/debian-12.yaml
configs/debian-11.yaml

Jalankan batch:

proxmox-cloud-image -batch batch.txt

Features:

• Process multiple config files sekaligus
• Max 3 concurrent jobs (parallel)
• Auto-skip lines yang kosong atau comment (#)
• Summary report di akhir

How It Works

1. Download cloud image dari URL yang diberikan
2. Customize image (resize, inject SSH key jika ada)
3. Upload image ke Proxmox host via SCP
4. Create VM menggunakan qm commands
5. Import disk dan configure VM
6. Setup cloud-init
7. Enable QEMU Guest Agent (jika di-enable)
8. Enable Proxmox firewall (jika di-enable)
9. Configure firewall rules (jika ada rules yang di-define)
10. Convert VM menjadi template dengan qm template

QEMU Guest Agent

QEMU Guest Agent adalah service yang berjalan di guest OS untuk:

• IP address discovery
• Graceful shutdown/reboot
• File system freeze/thaw
• Time synchronization

Enable dengan flag -guest-agent atau di config file:

guest_agent: true

Proxmox Firewall

Proxmox firewall bisa di-enable untuk template dengan flag -firewall atau di config file:

firewall: true

Firewall Rules

Kamu juga bisa define firewall rules langsung di config file:

firewall: true
firewall_rules:
  - type: in
    action: accept
    protocol: tcp
    dport: "22"
    comment: "SSH"
  - type: in
    action: accept
    protocol: tcp
    dport: "80,443"
    comment: "HTTP/HTTPS"
  - type: in
    action: accept
    protocol: icmp
    comment: "ICMP/Ping"
  - type: in
    action: drop
    comment: "Drop all other incoming"

Firewall Rule Fields:

• type: in (incoming) atau out (outgoing)
• action: accept, drop, atau reject
• protocol: tcp, udp, icmp, dll (optional)
• dport: destination port atau port range, contoh: 22, 80,443, 8000:9000 (optional)
• sport: source port (optional)
• source: source IP/CIDR, contoh: 192.168.1.0/24 (optional)
• dest: destination IP/CIDR (optional)
• comment: komentar untuk rule (optional)

Rules akan ditulis ke /etc/pve/firewall/<vmid>.fw di Proxmox host.

Firewall akan di-enable di network interface VM.

Clone Template

Setelah template dibuat, kamu bisa clone untuk membuat VM baru:

qm clone 9000 100 --name my-vm --full
qm set 100 --ipconfig0 ip=192.168.1.100/24,gw=192.168.1.1
qm set 100 --sshkeys /root/.ssh/id_rsa.pub
qm start 100

Notes

• Tool ini menggunakan SSH untuk koneksi ke Proxmox
• Pastikan SSH key sudah di-setup untuk passwordless login
• Image akan di-download ke /tmp dan di-upload ke Proxmox
• Template tidak bisa di-start, harus di-clone dulu
• QEMU Guest Agent akan otomatis ter-install di guest OS yang support
