Playbooks - combining tasks


Playbook is a collection of tasks that we want to group together.

lets review nginx install in a playbook format: nginx_install.yml


---
- hosts: virtualhosts
  become: true
  tasks:
    - name: install nginx
      apt:
        name: nginx
        state: latest
    - name: Setup nginx conf
      template:
        src=nginx.conf.tpl
        dest=/etc/nginx/nginx.conf
      notify: restart nginx
  handlers:
    - name: restart nginx
      service:
        name=nginx
        state=restarted

our template file is another file in the same directory that has the ubuntu nginx.conf content and is called: nginx.conf.tpl
