This repository contains a Packer template for building machine images that are centos 6.4 basic images in both vmware as well as virtualbox.
First, install Packer.
Then, clone this repository and cd into it.
Run the following:
$ packer build centos6.4-x86_64.json
You can choose to build only one type of image by running the following:
$ packer build -only=vmware centos6.4-x86_64.json
At the end of that, you'll have an AMI ready to go for Docker.
