- hosts: [yourhostlistgoeshere]
  remote_user: root
  vars:
    domainslisto:
       - site1.com
       - website2.xyz

....



  tasks:
    - name: copy vhosts
      template: src=virtualhost.conf dest=/etc/apache2/sites-available/{{ item }}.conf
      with_items: "{{ domainslisto }}"

    - name: a2ensite {{ item }}
      command: a2ensite {{ item }}
      with_items: "{{ domainslisto }}"
