Packer Example - CentOS 7 minimal Vagrant Box using Ansible provisioner

Current CentOS Version Used: 7.5 (1804)

Pre-built Vagrant Box:

• vagrant init geerlingguy/centos7
• See older versions: http://files.midwesternmac.com/

This example build configuration installs and configures CentOS 7 x86_64 minimal using Ansible, and then generates a Vagrant box file for VirtualBox.

The example can be modified to use more Ansible roles, plays, and included playbooks to fully configure (or partially) configure a box file suitable for deployment for development environments.

Requirements

The following software must be installed/present on your local machine before you can use Packer to build the Vagrant box file:

• Packer
• Vagrant
• VirtualBox (if you want to build the VirtualBox box)
• Ansible

Usage

Make sure all the required software (listed above) is installed, then cd to the directory containing this README.md file, and run:

$ packer build -var 'version=1.2.0' centos7.json

After a few minutes, Packer should tell you the box was generated successfully, and the box was uploaded to Vagrant Cloud.

Note: This configuration includes a post-processor that pushes the built box to Vagrant Cloud (which requires a VAGRANT_CLOUD_TOKEN environment variable to be set); remove the vagrant-cloud post-processor from the Packer template to build the box locally and not push it to Vagrant Cloud. You don't need to specify a version variable either, if not using the vagrant-cloud post-processor.

Testing built boxes

There's an included Vagrantfile that allows quick testing of the built Vagrant boxes. From this same directory, run one the following command after building the box:

$ vagrant up
