Define tasks / actions--- - hosts: webservers vars: http_port: 80 max_clients: 200 remote_user: root tasks: - name: ensure apache is at the latest version yum: pkg=httpd state=latest - name: write the apache config file template: src=/srv/httpd.j2 dest=/etc/httpd.conf notify: - restart apache - name: ensure apache is running service: name=httpd state=started

Define tasks / actions- hosts: webservers roles: - { role: servergrove.symfony2, symfony2_project_root: /var/www/vhosts/example.com/, symfony2_project_name: demo, symfony2_project_branch: master , symfony2_project_release: 1 }

Build packages for multiple platforms (deb, rpm, etc) with great ease and sanity.

fpm -s dir -t rpm -n "webapp" -v 1.0 /var/www/webapp !fpm -s dir -t deb -a all -n webapp -v 1.0 /etc/apache2/conf.d/my.conf /var/www/webapp
