I have been learning from this book Fabio Alessandro Locati, published under Packt>

There is one simple exercise where there is an example of “Installing and Configuring a Web Server”. The codes can be found at https://github.com/PacktPublishing/Learning-Ansible-2.X-Third-Edition/tree/master/Chapter02

Installing and Configuring a Web Server

The first set of codes deal with the installation and enabling of HTTPd package and services. In addition, both HTTP and HTPS must be able to pass through the firewalld

-- 
- hosts: all 
  remote_user: ansible
  tasks: 
    - name: Ensure the HTTPd package is installed 
      yum: 
        name: httpd 
        state: present 
      become: True 
    - name: Ensure the HTTPd service is enabled and running 
      service: 
        name: httpd 
        state: started 
        enabled: True 
      become: True 
    - name: Ensure HTTP can pass the firewall 
      firewalld: 
        service: http 
        state: enabled 
        permanent: True 
        immediate: True 
      become: True 
    - name: Ensure HTTPS can pass the firewall 
      firewalld: 
        service: https 
        state: enabled 
        permanent: True 
        immediate: True 
      become: True  

Reviewing and Running the Deployment, we can use the command to fire it.

$ ansible-playbook webserver.yaml --list-tasks
$ ansible-playbook -i host webserver.yaml

Publishing a Simple Website

Assuming the Website is a simple single-page website using a simple template call index.html.j2

--- 
- hosts: all 
  remote_user: ansible
  tasks: 
    - name: Ensure the website is present and updated 
      template: 
        src: index.html.j2 
        dest: /var/www/html/index.html 
        owner: root 
        group: root 
        mode: 0644 
      become: True  

Just a note that the “become: True” parameter represents the fact that the tasks should be executed with sudo access. In other words, the sudo user’s file should allow access
