It was a cloudy Tuesday afternoon when it walked into my office, an ubuntu-lts server from North East data centah', with ethernet cord from her hard-drives to the floor. There was nothing but bad news in her logs, and I had a good idea how it got there... It had a problem, the ruby was missing... and thats when I knew I had a job to do!

how to solve the case

detective-agency will read a Detectivefile, look at the facts, and generate an ansible playbook that should solve your case.

Take for example the case of the missing ruby:

# find the ruby interperter's version
#
investigate! :name => %q{ruby tuesday} do
  stake_out? %q{ruby -v | grep 'ruby 1.8'} do
    usual_suspects! :apt => "pkg=ruby1.8 state=absent"
  end

  stake_out! %q{ruby -v | grep 'ruby 1.9'} do
    usual_suspects! :apt => "pkg=ruby1.9.3 state=latest"
  end
end

You could then run detective-agency feeding its output to ansible:

$ detective-agency | tee install-ruby.yml
---
- hosts: all
  tasks:
  - shell: ruby -v | grep 'ruby 1'
    register: last_command
    ignore_errors: true
  - apt: pkg=ruby state=latest
    sudo: tru
    when: last_command.rc != 0
...

$ ansible-playbook -i inventory install-ruby.yml
