# 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

## Requirements

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

Install dependencies di Ubuntu/Debian:
```bash
sudo apt install qemu-utils libguestfs-tools
```

## Installation

### Build from source:

```bash
git clone <repo-url>
cd cloud-image
go build -o proxmox-cloud-image
```

### Install globally (Linux):

```bash
sudo cp proxmox-cloud-image /usr/local/bin/
sudo chmod +x /usr/local/bin/proxmox-cloud-image
```

Setelah install, bisa langsung dipanggil dari mana aja:
```bash
proxmox-cloud-image -h
```

## Usage

### Menggunakan CLI flags:

```bash
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"
```

### Auto-find VM ID (mulai dari 10000):

```bash
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"
```

Kalo `-vm-id` tidak diisi atau diset `0`, tool akan otomatis cari VM ID kosong mulai dari 10000.

### Dengan VLAN:

```bash
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
```

### Menggunakan config file:

```bash
proxmox-cloud-image -config config.yaml
```

Contoh `config.yaml`:
```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"
```

## Cloud Image URLs

### Ubuntu
- Ubuntu 22.04 (Jammy): `https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img`
- Ubuntu 20.04 (Focal): `https://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64.img`

### Debian
- Debian 12 (Bookworm): `https://cloud.debian.org/images/cloud/bookworm/latest/debian-12-generic-amd64.qcow2`
- Debian 11 (Bullseye): `https://cloud.debian.org/images/cloud/bullseye/latest/debian-11-generic-amd64.qcow2`

### CentOS Stream
- CentOS Stream 9: `https://cloud.centos.org/centos/9-stream/x86_64/images/CentOS-Stream-GenericCloud-9-latest.x86_64.qcow2`

## Flags

| Flag | Default | Description |
|------|---------|-------------|
| `-config` | - | Path ke config file (YAML) |
| `-image-url` | - | URL cloud image (required) |
| `-vm-name` | cloud-vm | Nama template |
| `-vm-id` | 0 | Template ID (0 = auto-find dari 10000+) |
| `-storage` | local-lvm | Nama storage Proxmox |
| `-memory` | 2048 | Memory dalam MB |
| `-cores` | 2 | Jumlah CPU cores |
| `-disk-size` | 20G | Ukuran disk |
| `-bridge` | vmbr0 | Network bridge |
| `-vlan-tag` | 0 | VLAN tag (0 = no VLAN) |
| `-ssh-key` | - | Path ke SSH public key |
| `-proxmox-host` | - | IP/hostname Proxmox (required) |
| `-proxmox-user` | root@pam | Proxmox user |
| `-proxmox-pass` | - | Proxmox password |

## 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. **Convert VM menjadi template** dengan `qm template`

## Clone Template

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

```bash
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
