[![Build Status](https://ci.rknet.org/api/badges/infra/packer-proxmox/status.svg)](https://ci.rknet.org/repos/infra/packer-proxmox)
[![License: MIT](https://img.shields.io/badge/License-MIT-blue.svg?label=license)](LICENSE)

This repository provides infrastructure-as-code examples to automate the creation of virtual machine images on Proxmox using [HashiCorp Packer](https://www.packer.io) and the [Packer Plugin for Proxmox](https://developer.hashicorp.com/packer/integrations/hashicorp/proxmox/latest/components/builder/iso). All examples are written in the HashiCorp Configuration Language `HCL2`.

This project is inspired by [bitop/packer-templates](https://gitlab.com/bitop/packer-templates/rocky).

## Requirements

**Packer**:

- HashiCorp [Packer](https://developer.hashicorp.com/packer/tutorials/docker-get-started/get-started-install-cli)
- HashiCorp [Packer Plugin for Proxmox](https://developer.hashicorp.com/packer/integrations/hashicorp/proxmox/latest/components/builder/iso) (`proxmox-iso`)

Required plugins are automatically downloaded during the `packer init` phase. These plugins are placed in the same directory as your Packer executable `/usr/local/bin` or `$HOME/.packer.d/plugins`.

## Configuration

### Step 1 - Download the release

Download the **latest** release.

### Step 2 - Download the Guest Operating Systems ISOs

1. Download the required guest operating system ISO images (e.g. `Rocky-9.3-x86_64-minimal.iso`).
2. Obtain the checksum type (e.g. `sha256`, `md5`, etc.) and checksum value for each guest operating system `.iso` image. This will be used in the build input variables.
3. Upload the guest operating system `.iso` images to your Proxmox server.

### Step 3 - Configure the Variables

All available [variables](https://developer.hashicorp.com/packer/docs/templates/hcl_templates/variables) are defined in the `variables.pkr.hcl` files. They can be overwritten using environment variables or in the `server.auto.pkrvars.hcl` file.

### Step 4 - Modify the Configurations and Scripts (Optional)

If required, modify the configuration and scripts files.

## Build

Initialize packer and start a build. Packer creates a local HTTP server to provide the kickstart file for the VM. For this to work, the Proxmox server must be able to reach the host IP of the Packer host.

> **Info:** Using the force flag will automatically remove existing _templates_ with a matching name or VMID.

```Shell
packer init rocky-9/
packer build -force rocky-9/
```
