This role configures RHEL/CentOS (minimal install) in preparation for it to be packaged as part of a .box file for Vagrant/VirtualBox deployment using Packer.
Prior to running this role via Packer, you need to make sure Ansible is installed via a shell provisioner, and that preliminary VM configuration (like adding a vagr
75D8
ant user to the appropriate group and the sudoers file) is complete, generally by using a Kickstart installation file (e.g. kickstart.cfg) with Packer.
An example array of provisioners for your Packer .json template would be something like:
"provisioners": [{
"type": "shell",
"execute_command": "echo 'vagrant' | {{.Vars}} sudo -S -E bash '{{.Path}}'",
"script": "scripts/ansible.sh"
},
{
"type": "ansible-local",
"playbook_file": "ansible/main.yml",
"galaxy_file": "requirements.yml"
},
{
"type": "shell",
"execute_command": "echo 'vagrant' | {{.Vars}} sudo -S -E bash '{{.Path}}'",
"script": "scripts/cleanup.sh"
}
],
The files should contain, at a minimum:
scripts/ansible.sh:
#!/bin/bash -eux
# Add the EPEL repository, and install Ansible.
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
yum -y install ansible python-setuptools
ansible/main.yml:
---
- hosts: all
become: yes
gather_facts: yes
roles:
- net2grid.vm-tools
You might also want to add another shell provisioner to run cleanup, erasing free space using dd, but this is not required (it will just save a little disk space in the Packer-produced .box file).
If you'd like to add additional roles, make sure you add them to the role_paths array in the template .json file, and then you can include them in main.yml as you normally would. The Ansible configuration will be run over a local connection from within the Linux environment, so all relevant files need to be copied over to the VM; configuratin for this is in the template .json file.

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
- hosts: all
roles:
- { role: net2grid.vm-tools }
