    Packer

    Packer

    Packer is a tool for creating identical machine images for multiple platforms from a single source configuration. It simplifies the process of building consistent, reproducible, and automated machine images for various cloud environments, virtual machines, and other platforms.

    🛠️ Installation

    macOS

    To install Packer on macOS, use the Homebrew package manager:

    brew tap hashicorp/tap brew install hashicorp/tap/packer

    Windows

    For Windows, download and install Packer from the official website:

    Linux

    Ubuntu/Debian

    To install Packer on Ubuntu or Debian-based distributions, follow these steps:

    1. Add HashiCorp's GPG key:

      wget -O- https://apt.releases.hashicorp.com/gpg | gpg --dearmor | sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg

    2. Add the Packer repository to your system:

      echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list

    3. Install Packer:

      sudo apt update && sudo apt install packer

    🔌 Plugins

    Packer supports a wide range of plugins to extend its functionality, allowing you to create machine images for different platforms.

    Proxmox Builder

    The Proxmox Packer builder enables you to create virtual machines and store them as new images. It includes two types of builders:

    Authentication

    You can authenticate to Proxmox using the following environment variables:

    • PROXMOX_URL

    • PROXMOX_USERNAME

    • PROXMOX_PASSWORD

    • PROXMOX_TOKEN

    See the Proxmox Authentication Guide for more details.

    Example Template

    Here is a basic example of a Proxmox builder template (Work In Progress - WIP):

    # Packer Template for Proxmox builder "proxmox-iso" 
{   
	iso_url = "http://example.com/ubuntu.iso"   
	iso_checksum = "sha256:abc123..."   
	vm_name + "ubuntu-template"   
	os_type = "ubuntu"   
	cpus = 2   
	memory = 4096   
	disk_size = 10240    
	# Additional Proxmox-specific settings go here 
}
