(cross posting here as I originally posted in puppet-users - I figure the question is more of a dev one then for puppet-users)
Hi everyone, I'm experimenting with converting some of my live puppet content to Ruby DSL and have found a few gaps I wouldn't mind some advice on. I'm not sure how many of you have already experimented in this arena yet. I've already read Dan Bode's excellent blog article on the subject: http://www.puppetlabs.com/blog/ruby-dsl/ I know the Ruby DSL is quite new - but I figured perhaps some of these items deserve to be tickets (or perhaps documented) and I thought I'd ask first :-). 1. Defaults How do I set defaults in Ruby DSL? For example what is the ruby DSL equivalent to this: Service { hasstatus => true } 2. Top scope I notice the convenience methodology does not work at 'top scope' for example this will fail: file "/tmp/zzz", :content => "foo" But this will not: node "default" do file "/tmp/zzz", :content => "foo" end Is there a proper way to call resources without using the convenience methods? Or perhaps is there a way to define elements that reside in top scope? 3. Class resource I think Dan Bode already raised this as a bug: https://projects.puppetlabs.com/issues/5236 The following returns an error 'method_missing': hostclass :foo do notify "bar" end node "default" do hostclass "foo", :stage => "baz" end This is because hostclass has not been defined as a convenience method it would seem. Just like issues 2 If someone knows a way to call a resource directly without requiring the convenience method that would be a decent enough work-around. 4. exec Resource The 'exec' resource as a convenience method is overlapping with the ruby 'exec' method. So if you do this: node "default" do exec "ls", :command => "/bin/ls" end You get: can't convert Hash into String on node obelisk.usr.bob.sh Returned from the Kernel.exec call. 5. Referencing other resources I'm not quite clear how to reference other resources that already exist. This is obviously a problem for the 'require' attribute: node "default" do package "foo", :ensure => "installed" service "foo", :enable => "true", :ensure => "running", :require => ??? end 6. Chaining Resources Is there a syntactical equivalent to this in Ruby DSL yet? For example: Stage[pre] -> Stage[main] -> Stage[post] Without knowing how to solve 5 I'm kind of stuck when it comes to defining dependencies :-).
