Cloud Init Installer Script for Proxmox VE

Table of Contents

OpsLinuxSec CLOUD INIT INSTALLER is a shell-based tool designed to automate the configuration and deployment of virtual machines in Proxmox Virtual Environment (PVE) using Cloud-Init.
This tool helps streamline VM provisioning — if the required ISO image is not found under /var/lib/vz/images/, the script will fetch it automatically.

Requirements

Before using this script, make sure your system has:

wget installed (for ISO downloads)
Proxmox VE installed and running
root user privileges

The script will auto-check and install missing dependencies.

How to Use

1. Download and Prepare the Script

wget https://github.com/ryanachmad12/cloud-init-prox-script/raw/refs/heads/main/installer.sh
chmod +x installer.sh

2. Run the Script

bash installer.sh

Installation Flow

Step 1: Dependency Check

Step 5: Check Image Availability

If the image is not found, it will prompt you to download:

Image not found at /var/lib/vz/images/focal-server-cloudimg-amd64.img
Would you like to download it? (yes/no)

Step 6: Set Disk Size and VM Configuration

You will be prompted to define VM specs:

Enter disk size (GB): 6
Image resized.

Enter VM ID: 222
VM ID already exists. Please choose another.

Enter VM Name: example
Enter RAM (MB): 512
Enter CPU cores [default: 1]: 
Enable QEMU agent [default: 1]:

Step 7: Choose Target Storage

It will list available storages like:

Target Disk
┌────────────────┬───────────┬─────────┬────────┬───────────┬─────────┬────────┬───────────┬───────────┬───────────────┐
│ content        │ storage   │ type    │ active │ avail     │ enabled │ shared │ total     │ used      │ used_fraction │
╞════════════════╪═══════════╪═════════╪════════╪═══════════╪═════════╪════════╪═══════════╪═══════════╪═══════════════╡
│ rootdir,images │ local-lvm │ lvmthin │ 1      │ 10.10 GiB │ 1       │ 0      │ 11.80 GiB │ 1.70 GiB  │ 14.42%        │
└────────────────┴───────────┴─────────┴────────┴───────────┴─────────┴────────┴───────────┴───────────┴───────────────┘

Enter storage (e.g., local-lvm):

Step 8: VM Creation Completed

Once all parameters are set, the VM will be built and configured automatically:

VM ID 222 created successfully.
Please configure the network settings manually.

Convert to Template

Once the VM is created, you can convert it to a template using Proxmox for future rapid deployments.

Final Notes

Make sure the server has enough disk space for image storage and VM files.
After creation, network configuration must be done manually via PVE GUI or CLI.
