# Steps for creating VM templates with Hashicorp Packer

As this is one of the early steps, the assumption is made that these commands will be run on a jumpbox/laptop.

Templates will always live on <template-node> within the cluster.

Steps to install Packer:

```bash
brew tap hashicorp/tap
brew install hashicorp/tap/packer
```
