Roles to JSON broken on Chef-Solo

consiliens · July 16, 2010, 8:01pm

Why does chef-solo require a key to generate a JSON representation of a
role for use with chef-solo?

I’m using the command from the wiki.
http://wiki.opscode.com/display/chef/Chef+Repository#ChefRepository-rolesorrole\rolename\

rake role[webserver]

/usr/local/lib/ruby/gems/1.8/gems/chef-0.9.6/lib/chef/rest/auth_credentials.rb:62:in
`load_signing_key’: I cannot read ~/.chef/user.pem, which you told me to
use to sign requests! (Chef::Exceptions::PrivateKeyMissing)

rake roles calls knife role from file which assumes you want to
upload the role to the server. With chef solo, you are not required to
convert the role to JSON before using it, however--you should be able
to just configure your role_path in solo.rb and run with it. I see
this is not documented on the roles page in the wiki, and the chef
solo page states that you have to convert to JSON first, which is
incorrect. I don't have time to fix these right now, but I'll make a
note to fix them as I'm able. If you're willing to fix them, that
would be greatly appreciated.

I tried role_path and it's still not working. I'll update the wiki once
it works. Here's the code I'm using.

sudo chef-solo --config ./solo.rb

Contents of solo.rb

file_cache_path File.expand_path( '..', FILE )
cookbook_path File.expand_path( '../cookbooks', FILE )
role_path File.expand_path( '../roles', FILE )
node_name 'nginx'

../roles contains nginx.rb that uses the Role DSL as defined on the
wiki. http://wiki.opscode.com/display/chef/Roles

What error are you getting? Chef::Exceptions::RoleNotFound?
Unfortunately, there's not a lot of debug info to be had here, but if
you're willing to hack some into the code, here's where you'd do it:

github.com

chef/chef/blob/5f8f81915cfa2bc60cfd5d0cb2899a1188d8731c/chef/lib/chef/role.rb#L253-267


      
            (couchdb || Chef::CouchDB.new).create_design_document("roles", DESIGN_DOCUMENT)
          end
          
          # As a string
          def to_s
            "role[#{@name}]"
          end
          
          # Load a role from disk - prefers to load the JSON, but will happily load
          # the raw rb files as well.
          def self.from_disk(name, force=nil)
            js_file = File.join(Chef::Config[:role_path], "#{name}.json")
            rb_file = File.join(Chef::Config[:role_path], "#{name}.rb")
          
            if File.exists?(js_file) || force == "json"
              JSON.parse(IO.read(js_file))
            elsif File.exists?(rb_file) || force == "ruby"
              role = Chef::Role.new
              role.name(name)
              role.from_file(rb_file)

There is no error. The cookbooks just never run. I'm using the exact
same files on the Opscode platform without issue. Is setting node_name
the proper way to tell chef-solo which role to apply?

I'll add the debug info and see what happens.

Oh, looking at your command-line invocation of chef-solo, it seems
like you need to also provide a JSON file with a run_list that
specifies which roles chef should use:

The CAPTCHA on every edit combined with no preview button made it
difficult to contribute. It would be nice if Knife was able to locally
convert between the Ruby DSL and the JSON syntax.

First of all, thank you. Every tiny bit that we can improve the docs
helps. I don't know what we can do about the CAPTCHAs, but confluence
