Order Not sequential Sequential Sequential Documentation Confusing Chaotic Excellent Popularity 1st 2nd 3rd Extra Requirements - - ansible Overall Learning Curve Moderate High Low
16. Pratical Example Nginx + PHP5: Ansible
17. Vagrantfile config.vm.provision "ansible" do |ansible| ansible.playbook = "playbook.yml" end
18. Playbook --- - hosts: all sudo: true tasks: - name: Update apt apt: update_cache=yes - name: Install Nginx apt: pkg=nginx state=latest - name: Install PHP5-fpm apt: pkg=php5-fpm state=latest
