puma recipe failing on CentOS - nginx

Question

I'm trying create a chef-solo recipe for using puma on centos6. All of the guides that I see are targeted towards Ubuntu using Upstart. I've tried making modifications to use init but it still fails with the error * /etc/init.d/puma-manager does not exist!.
/recipes/puma.rb
# add puma init conf
template '/etc/init/puma.conf' do
source 'puma-init.conf.erb'
mode 0644
end
# add puma manager conf
template '/etc/init/puma-manager.conf' do
source 'puma-manager.conf.erb'
mode 0644
end
# add puma conf
template '/etc/puma.conf' do
source 'puma.conf.erb'
mode 0644
end
cookbook_file '/etc/init.d/puma' do
source 'puma'
owner 'deploy'
group 'deploy'
mode '0755'
action :create
end
cookbook_file '/usr/local/bin/run-puma' do
source 'run-puma'
owner 'deploy'
group 'deploy'
mode '0755'
action :create
end
# add puma app conf
template "#{node['app_shared_path']}/config/puma.rb" do
source 'puma.rb.erb'
mode 0644
# notifies :restart, 'service[puma]', :delayed
end
service 'puma-manager' do
provider Chef::Provider::Service::Init
supports ['start', 'stop', 'restart', 'status']
action :start
end

First of all, your service name seems to be wrong. It seems like it should be called service 'puma' instead of puma-manager.
Besides that, a init script from Debian/Ubuntu will not work on CentOS without modifications. Some required files like the helper methods from the init-functions do not exist on CentOS.
Depending on the script, those modification can be quite complex and sometimes it's better to write a new script from scratch.
Anyway, there is a non-official CentOS init script example for Puma here:
https://github.com/puma/puma/issues/178
But it is a little old/untested and I'm not sure it will work without modification.
