[chef] Run a ruby block as another user?

[Marcelo de Moraes Serpa < >]

Hi list,

I'm using the ruby_block resource to write the contents of a secure databag item into /home/deploy/.ssh (a private key). Problem is, that directory has restricted permissions, and the key is not saved. Here's the code I'm using:

ruby_block "write_key" do

  block do

    require 'fileutils'

    f = ::File.open("/home/deploy/.ssh/id_deploy","w")

    f.print(secrets["deploy_key"])

    f.close

    FileUtils.chown("deploy","deploy","/home/deploy/.ssh/id_deploy")

  end

  not_if do ::File.exists?("/home/deploy/.ssh/id_deploy"); end

end

Is there a way to tell ruby_block to run as another user? Or is there a better way to do that?

Thanks!

- Marcelo.
