ec2 public_hostnames

You should be able to do this with a Proc:

chef_role :web, '*:*', :attribute => Proc.new do |n|
  n['cloud']['public_hostname']
end

There's a more complex example in the readme: https://github.com/cramerdev/capistrano-chef#examples

Let me know if that doesn't work for you, or if there's anything that would make it clearer either in the docs or the API. Thanks!

Not to assume this should just work copy and paste, but I keep getting:

./config/deploy.rb:24:in `new': tried to create Proc object without a block (ArgumentError)

with that code, as well as fiddling around with the expanded example on the readme. I can see that the attribute I need is node['ec2']['public_hostname'].

However, this returned the private IP addresses correctly:

chef_role :web, 'roles:web', :attribute => { :eth0 => :inet }

Thanks for your help!

Ruby can sometimes be picky about blocks and precedence, something like Proc.new( { |n| ... } ) might work too.

Ah. This ended up working:

chef_role :web, 'roles:web', :attribute => Proc.new { |n| n['ec2']['public_hostname'] }

Thanks again!
