WHAT IS ANSIBLE?

Ansible is an automation tool

WHY ANSIBLE?

Ansible is simple

• Written in Python
• No agent needed on the server
• YAML configuration
• 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:

https://github.com/MaximeThoonsen/symfony-ansible

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
