[chef] Re: chef & rvm

[John Merrells < >]

Just for the record, I've got this working quite nicely. Here's what I did...

I wrote a simple cookbook to install rvm and some rubies.

============================================================
include_recipe("zlib") # for rvm
package 'curl' # for ree
package 'libreadline5-dev' # for ree

cookbook_file "/root/.bashrc" do
  source "bashrc"
  mode "0644"
end

cookbook_file "/root/.profile" do
  source "profile"
  mode "0644"
end

# to update
# rvm update --head

bash "install rvm" do
  environment "HOME"=>"/root"
  code <<-EOH
  bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head ;)
  EOH
  not_if { ::FileTest.exists?("/usr/local/rvm") } # JCM check version
end

bash "install ruby 1.8.7" do
  environment "HOME"=>"/root"
  code <<-EOH
  source '/usr/local/rvm/scripts/rvm'
  rvm install ruby-1.8.7-p299
  rvm 1.8.7 gem install bundler --no-ri --no-rdoc
  EOH
  not_if { ::FileTest.exists?("/usr/local/bin/rvm/rubies/ruby-1.8.7-p299") } 
end

bash "install ruby enterprise edition 1.8.7" do
  environment "HOME"=>"/root"
  code <<-EOH
  source '/usr/local/rvm/scripts/rvm'
  rvm install ree-1.8.7-2010.02
  rvm ree gem install bundler --no-ri --no-rdoc
  EOH
  not_if { ::FileTest.exists?("/usr/local/bin/rvm/rubies/ree-1.8.7-2010.02") }
end
============================================================

Since I'm using bundler I did't really have any gem_package calls,
which I thought would be the biggest challenge here. So, now I call
bundler like this....

============================================================
    execute "bundle_install" do
      command "rvm ree;bundle install"
    end
============================================================

...and then I'm using runit to spin up my ruby daemon, so the run
script changed to....

============================================================
#!/bin/bash
source '/usr/local/rvm/scripts/rvm'
rvm use ree
exec 2>&1
exec /usr/bin/env my_ruby_daemon
============================================================

...now I can switch between rubies super easily, and all the ruby install and 
setup work is done by rvm, rather than chef, so those {ruby|rails|passenger}
_enterprise cookbooks can go away, and now I can play with rubinious,
1.9.2, rails30, without worrying about messing up my environment.
