• Rhel '>= 6.0'

• Chef '>= 12.5'

• apt
• cop_ntp

3. htop
4. vim
5. nano

• node['packages']['install'] = array of packages to install.

Usage

Here's an example base role that will install basic OS packages. This example adds the net-tools package.

name 'base'
description 'install base OS packages'

override_attributes(
    'packages' => {
        'install' => {
            'net-tools'
        }
    }
)

run_list(
    'recipe[cop_base::default]'
)

Environment Variables

You can set environment variables for projects by following the following format:

default['environment_vars'] = {
    'VARIABLE': 'VALUE',
    'VARIABLE_TWO': 'VALUE_TWO'
}

It will loop through each key value pair and add them to the environment's /etc/environment file.

NOTE: You will not have access to these variables within the context of chef so you will have to use the :environment property within the commands that need context.

Testing

• http://kitchen.ci
• http://serverspec.org

Testing is handled with ServerSpec, via Test Kitchen, which uses Docker to spin up VMs.

ServerSpec and Test Kitchen are bundled in the ChefDK package.

Running

Get a listing of your instances with:

$ kitchen list

Run Chef on an instance, in this case default-ubuntu-1204, with:

$ kitchen converge default-ubuntu-1204

Destroy all instances with:

$ kitchen destroy

Run through and test all the instances in serial by running:

$ kitchen test
