chef variable conflicts

README.md

I find that my custom resource (not LWRP) gets a conflict with the variable "service_name" in the alert logic cookbook.

Steps to reproduce:

Create custom resource with attribute "service_name"

Create a runlist that includes alert_logic cookbok and recipe with custom resource Make sure alert logic is first in the run list (unproven theory)

Expected outcome

The powershell script should run as follows:

sc.exe create 'NDConfigurationServer' binPath= C:\\SomeFolder\\ndConfServer.exe start= auto displayname= 'ND Configuration Server'

Actual outcome

powershell script runs:

sc.exe create 'alert_logic' binPath= C:\\SomeFolder\\ndConfServer.exe start= auto displayname= 'ND Configuration Server'

custom_resource.rb

resource_name :nd_configurator
property :neserv_location, String, required: true
property :domain, String, required: true
property :user, String, required: true
property :port, String, required: true
property :service_name, String, required: true
property :display_name, String, required: true

action :create do
  powershell_script 'Install ND Configuration Server' do
    guard_interpreter :powershell_script # http://stackoverflow.com/a/25413011/1626687
    code <<-EOH
      sc.exe create '#{service_name}' binPath= #{neserv_location}\\ndConfServer.exe start= auto displayname= '#{display_name}'
    EOH
    action :run
    not_if "Get-Service -Name '#{display_name}'"
  end
end
end

foo.rb

omain = node['domain']
user   = 'nereg'
port   = '8081'

service_name    = 'NDConfigurationServer'
display_name    = 'ND Configuration Server'

if node['kernel']['cs_info']['domain_role'].to_i == 1 || node['kernel']['cs_info']['domain_role'].to_i == 3

  # Custom resource that accepts actions :create, :stop, :start, :restart
  nd_configurator 'ndconf server' do
    neserv_location  node['nd-web']['neserv_path']
    domain           domain
    user             user
    port             port
    service_name     service_name
    display_name     display_name
    action :create
  end

end
