A better way to use the cookbook would be to create files in sudoers.d for each entry. https://github.com/opscode-cookbooks/sudo#lwrp

Hi,

I am trying to figure out how best to use the sudo cookbook.  My cookbook is called masterwrap.

Berkesfile:


masterwrap/metadata.rb:

name             'masterwrap'
maintainer 'The Authors'
maintainer_email ' " target="_blank"> '
license 'all_rights'
description 'Installs/Configures masterwrap'
long_description 'Installs/Configures masterwrap'
version '0.1.0'

depends 'git', '~> 4.1.0'
depends 'sudo', '~> 2.7.1'
depends 'users', '~> 1.8.0'

masterwrap/recipes/default.rb:

#
# Cookbook Name:: masterwrap
# Recipe:: default
#
# Copyright (c) 2015 The Authors, All Rights Reserved.

include_recipe 'git'
include_recipe 'masterwrap::users'

masterwrap/recipes/users.rb:

#
# Cookbook Name:: masterwrap
# Recipe:: users
#
# Copyright (c) 2015 The Authors, All Rights Reserved.

include_recipe 'sudo'
include_recipe 'users'

%w(deploy sysadmin).each do |group|
users_manage group do
data_bag 'users'
action [ :remove, :create ]
end
end

sudo 'sysadmin' do
group '%sysadmin'
nopasswd false
end

If I converge at this point, my vagrant user would stop having passwordless sudo access.  To make sure that does not happen, I have the following masterwrap/.kitchen.yml file:

---
driver:
name: vagrant

provisioner:
name: chef_zero

platforms:
- name: ubuntu1404
driver:
box: ubuntu/trusty64
box_url: ubuntu/trusty64
attributes:
authorization:
sudo:
users: ['vagrant']
passwordless: true
include_sudoers_d: true

suites:
- name: default
data_bags_path: 'test/fixtures/data_bags'
run_list:
- recipe[masterwrap::default]
attributes:
The problem is that I DO want a password prompt for my sudo access for non-vagrant users, but I am not sure how to go about achieving that.  Here is my current /etc/sudoers file after the converge:

# This file is managed by Chef.

# Do NOT modify this file directly.

Defaults      !lecture,tty_tickets,!fqdn

# User privilege specification

root          ALL=(ALL) ALL

vagrant ALL=(ALL) NOPASSWD:ALL

# Members of the group 'sysadmin' may gain root privileges

%sysadmin ALL=(ALL) NOPASSWD:ALL

===

Given the node's structure, I think the sudo cookbook assumes everyone who is granted sudo access via the cookbook will want the same setting for passwordless, which is not the desired outcome in my case.  Is there a way around this assumption or a better way for me to use the sudo cookbook?  Thank you for your help.

Sincerely,
Jimmy
