# Install packer
|

Install packer on your system (or dedicated pxc container):
|
|
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).
