Igor,

I've been trying to get rails_ghetto up and running in a test Vagrant VM, but I'm having a hard time - mainly because I'm still quite new to all those chef[solo] concepts, I'd say. If you could give me a hand, I'd be really grateful. Here's the portion of my Vagrantfile that sets up the chef-solo integration:

config.vm.provision :chef_solo do |chef|
    chef.cookbooks_path = "/Users/fullofcaffeine/workspace/code/chef-repo/cookbooks"
    chef.roles_path = "/Users/fullofcaffeine/workspace/code/chef-repo/roles"
    chef.data_bags_path = "/Users/fullofcaffeine/workspace/code/chef-repo/data_bags"
    #run list
    chef.add_recipe("rails_ghetto::user")
    chef.add_recipe("rails_ghetto::deploy")
    chef.add_recipe("rails_ghetto::nginx_sites_enable")
    
    #chef.add_recipe("php")
    chef.json = { "rails_ghetto" => {
    "deployment_user" => "deploy",
     "deployment_group" => "deploy",
     "apps_root" => "/var/www/apps",
     "libs" => ["libxslt-dev","libxml2-dev"],
     "applications" => {"sample" => {
          "repository" => " :fullofcaffeine/raks.git",
          "revision" => "master",
          "deploy_key" => "/home/root/.ssh/github",
          "unicorn_port" => "8080",
          "server_name" => "production.example.com",
          "compile_assets" => "true",
          "run_migrations" => "true",
          "rails_environment" => "production",
           "database" => { "adapter" => "postgresql", 
                           "database" => "sample2", 
                           "username" => "root", 
                           "password" => "changeit" },
           }
          },
         "recipes" => ["rails_ghetto::user","rails_ghetto::deploy","rails_ghetto::nginx_sites_enable"]
       }
    }
    
  end

There are some fields that I need to change, but I wanted to let it run first and then start the trial and error. However, it just fails with a message that I can't interpet (tried googling but didn't find anything useful). Here's the stacktrace:

Any ideas?

Thanks in advance!

Wow! Thanks for the comprehensive reply Andrea!

I'll try those suggestion tonight. @Igor, I'll check out rails_ghetto as well! I'll share my experience here afterwards.

Meanwhile, I have a quick question regarding the approach of Bryan Baugher, in this thread:


How would that work?

Thank you *very much* again for the replies!

- Marcelo.

Andrea,

Wow, thanks, I've totally missed that I can do it like that. I thought that there maybe a better way to do it but totally missed most obvious way.

Hi Marcelo,

I've already mentioned in this list but I have a cookbook which is basically
what you need. It manages deployment of several very similar rails
applications. As Andrea mentioned if you have different applications it is
better to have a separate cookbooks for them. But for your case here is the
cookbook - https://github.com/iafonov/rails_ghetto. I'm 100% sure that you'd
have to change it for your needs. I'm not a big fan of data bags (this
cookbook was initially created for chef-solo) but if you are - you can quite
easily alter it to use data bags instead of attributes.

I had a look at rails_ghetto some time ago and I like it. If anything,
it shows a big benefit of the "new" application cookbook: you were
able to reuse its LWRPs to add functionality on top.


One question though: how come you rolled your own nginx_sites_enable
instead of using application_nginx? Any missing functionality there?
At a cursory glance it looks like a perfect match, you just need to
specify your own template.
I.e. in your recipes/deploy.rb:

rails_applications do |name, app|
application name do
…
nginx do
template "nginx_site.erb"
cookbook_name "rails_ghetto"
end
end
end

And you'd be pretty much set.

Did you try that and hit any roadblock?

Andrea
