12. Ansible as Provisioner #Vagrantfile Vagrant.configure("2") do |config| config.vm.box = "hashicorp/precise64" config.vm.provision "ansible" do |ansible| ansible.playbook = "playbook.yml" end end
13. DEMO
15. WRITING PLAYBOOKS
16. Variables --- - hosts: all sudo: yes vars: web_server: nginx tasks: - name: Install {{ web_server }} apt: pkg={{ web_server }} state=latest
17. Facts
18. Conditionals - name: "shutdown Debian flavored systems" command: /sbin/shutdown -t now when: ansible_os_family == "Debian" - name: foo is not defined fail: msg="Bailing out. this play requires 'bar'" when: bar is not defined
19. Looping: with_items tasks: - name: Install Packages apt: pkg={{ item }} state=latest with_items: - nginx - php5-fpm - git
20. Looping: with_items --- - hosts: all sudo: yes vars: sys_packages: [ 'nginx', 'php5-fpm', 'git' ] tasks: - name: Install Packages apt: pkg={{ item }} state=latest with_items: sys_packages
21. Templates <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot {{ doc_root }} <Directory {{ doc_root }}> AllowOverride All Require all granted </Directory> </VirtualHost>
22. Templates - Usage - name: Change default apache vhost template: src=templates/apache.tpl dest=/etc/apache2/sites-available/000-default.conf
23. Handlers (services) --- - hosts: all sudo: yes vars: - doc_root: /vagrant tasks: - name: Change default apache vhost template: src=templates/apache.tpl dest=/etc/apache2/sites- available/000-default.conf notify: restart apache handlers: - name: restart apache service: name=apache2 state=restarted
24. Handlers (services) --- - hosts: all sudo: yes vars: - doc_root: /vagrant tasks: - name: Change default apache vhost template: src=templates/apache.tpl dest=/etc/apache2/sites- available/000-default.conf notify: restart apache handlers: - name: restart apache service: name=apache2 state=restarted
26. ORGANIZING PLAYBOOKS
27. Including Tasks --- - hosts: all sudo: true vars: doc_root: /vagrant/web tasks: - include: tasks/init.yml - include: tasks/nginxphp.yml handlers: - name: restart nginx service: name=nginx state=restarted
28. Roles . ├── playbook.yml └── roles ├── init │ └── tasks │ └── main.yml └── nginxphp ├── handlers │ └── main.yml ├── tasks │ └── main.yml └── templates └── vhost.tpl #playbook.yml --- - hosts: all sudo: true vars: doc_root: /vagrant/web roles: - init - nginxphp

35. Running Ansible on Vagrant vms $ ansible all -i [inventory] -u vagrant --private-key=[key] -a "php -v" $ ansible-playbook -i [inventory] -u vagrant --private- key=[key] demo01.yml .vagrant/provisioners/ansible/inventory/vagrant_ansible_inventory .vagrant/machines/default/virtualbox/private_key
