WHAT IS ANSIBLE?

Ansible is an automation tool

WHY ANSIBLE?

Ansible is simple

A little more about Ansible

  • Jinja2 templating (like Twig)

Many modules

  • Command : command, script, shell
  • Database : mongodb, mysql, postgresql, redis, riak
  • Source Control : git, github_hooks
  • System : authorized_key, cron, hostname, ping, user
  • Utilities : assert, debug, fail, include_vars, pause
  • ...

Let's have a look at a playbook:

Vagrantfile

 

  # Ansible
  config.vm.provision "ansible" do |ansible|
    ansible.sudo = true
    ansible.playbook = "provision/playbook.yml"
    ansible.limit = "vagrant" # hosts group
    ansible.inventory_path = "provision/hosts/vagrant"
    ansible.verbose = "v" #Use vvvv to get more log
  end

Vagrant tasks
