# What does this stuff do?
Packer is a tool that can create Virtual Machine templates from code.  
This repository hosts the code for a customized templates used in Siempie's home environment using the Proxmox Hypervisor.  

# Template
Inside the template packer does:
 - Install updates
 - Install tools; curl, qemu-guest agent, sudo and wget.  
 - Install Ansible user with private key
 - Clean guest (machine-id, logs, package cache, etc)
  
Other information to know:
 - Template hostname: `localhost`
 - packer username: `packer`
 - packer password: `packer`

# Install packer
Install packer on your system:  
https://developer.hashicorp.com/packer/tutorials/docker-get-started/get-started-install-cli

# Variables
Copy the `variables.pkrvars.hcl.example` file to `variables.pkrvars.hcl` and change the variables.

# Initialize the project and install the proxmox provider
This will initialize packer and install the required proxmox plugin.
```
packer init -var-file variables.pkrvars.hcl ubuntu24/packer.pkr.hcl
```

# Customization
Since packer allows either an inline or a script execution there is a script per template.
See the table above for the specific location per template.

# Usage
Ubuntu 24 Template:
```
packer build -force -var-file variables.pkrvars.hcl ubuntu24/packer.pkr.hcl
```
Note: the `-force` flag removes an already existing VM or Template with the same ID (999).
