Chef allows making custom resources through LWRPs.  A “LightWeight Resource and Provider” inherits the name of the cookbook that defines it.  So when you see a resource not included in the Chef framework and it’s name is “hostsfile_entry”, that means a cookbook called “hostsfile” has a defined resource called “entry” in hostsfile/resources/entry.rb and a defined provider in hostsfile/providers/entry.rb.

The LWRP reference should shed more light on this.

Also, there’s this great tutorial:

What `hostsfile` cookbook are you using? Is it this one? https://github.com/customink-webops/hostsfile http://community.opscode.com/cookbooks/hostsfile

Looking at the code on github, this file should be providing the hostsfile_entry resource: https://github.com/customink-webops/hostsfile/blob/master/resources/entry.rb Note that the name of the resource is inferred from the cookbook name plus an underscore plus the file name so you won’t necessarily see the string “hostsfile_entry” in the source.

ok you're right this file is included and contains functions. I've finally made it work with a new fresh repository. where can I find more information about this naming conventions and how it works ? is it related to ruby (I'm not yet an experimented ruby coder) ?

thanks


In any case, try running with debug logging (`chef-client -ldebug`) and look for a message like "Loading cookbook #{cookbook_name}'s resources from #{filename}” to confirm that the cookbook is getting loaded.

Hi Cyril,

There’s not enough information to go on.  Can you provide some additional stats?  It would help to have: cookbook version for each (I’m guessing you’re using the community cookbooks named ‘hostname’ and ‘hostsfile’?) as well as a stacktrace of the chef run (chef-client?  chef-solo?) giving you an error, and which platform you’re running this on.

You can remove any sensitive information from the logs.  But the more info you can provide, the easier it will be to troubleshoot.

yes :

$ grep depends ../../hostname/metadata.rb 
depends "hostsfile"

Does cookbooks/hostname/metadata.rb contain the line:  “depends hostsfile” ?

Hi,

I've installed cookbook hostname but neither me neither chef could find the resource hostsfile_entry :

$ ack -i --ruby hostsfile_entry .
cookbooks/hostname/recipes/default.rb
44:  hostsfile_entry "localhost" do
50:  hostsfile_entry "set hostname" do

Anyone ?
