Question

I have created a LWRP (my first time) but it doesn’t seem to work as required. I am not sure if I am missing something or did something wrong. The opscode documentation is horrible. I have show my code below:

Provider

puts "FOO"

def restart_process
  @svc = Chef::Resource::RestartProcesses.new(new_resource.name)
  Chef::Log.debug("Restarting services according to the box")
  notifies :run, resources(:execute => 'restart-storm')
end

puts "BAR"

action :restart do

  execute 'restart-process' do
    command <<-EOH
      echo "-------Executing restart process--------"
      #Some bash code
    EOH
  end
end

Resource

actions :restart

attribute :name, :kind_of => String, :name_attribute => true

def initialize(*args)
  super
  @action = :restart
end

Recipe from which the resource is called

template "#{install_dir}/####Something" do
  source "someSource.erb"
  variables(
    ###Some variables
  )

  notifies :run, 'nameOfCookbook_nameOfResource[process]'
end

nameOfCookbook_nameOfResource "process" do
  action :nothing
end

The chef output shows FOO BAR but it doesn’t print anything inside my bash script. So it doesn’t run the bash. Any pointers?

Answer 1

Don’t you need to tell the instance to run the action :restart

like

restart = nameOfCookbook_nameOfResource "process" do
  action :nothing
end

restart.run_action(:restart)

I know you’ve set the initialize to say restart but I think passing action :nothing overwrites that so either force it to run when you want by following the above example or within the template part notify the actual action you want as such

notifies :restart

By running this myself I saw an action of :nothing executed on the resource only. Not the default behaviour which in my case would have been :stop

By changing the notification to :stop it had the expected behaviour.

My understanding from the log is you have told your resource to run but it’s action is :nothing so it does nothing.
