Creating an Nginx role

We will now create a separate role for Nginx and move the previous code that we wrote in the simple_playbook.yml file to it, as follows:

1. Create the directory layout for the Nginx role:

   $ mkdir roles/nginx
   $ cd roles/nginx
   $ mkdir tasks meta files
   $ cd tasks
   

2. Create the install.yml file inside roles/base. Move the Nginx-related tasks to it. It should look like this:

   ---
    - name: add official nginx repository
      apt_repository: repo='deb http://nginx.org/packages/ubuntu/ lucid nginx'
    - name: install nginx web server and ensure its at the latest version
      apt: name=nginx state=latest force=yes

3. We will also create the service.yml file to manage the state of the Nginx daemon:

   ---
    - name: start nginx service
      service: name=nginx state=started

4. We looked at the include directive earlier. We will use it to include both the install.yml and service.yml files in the main.yml file, as follows:

   ---
   # This is main tasks file for nginx role
    - include: install.yml
   - include...
