I have been learning from this book Fabio Alessandro Locati, published under Packt>. The example can be found at https://github.com/PacktPublishing/Learning-Ansible-2.X-Third-Edition/tree/master/Chapter06

Today I am learning about working with notification. One of the biggest advantages of Ansible is its ability, compared to a bash script to notify. The 6 tools which Ansible could easily work with include

• Email Notification
• Ansible XMPP/Jabber
• Slack and Rocket Chat
• Sending a message to an IRC Channel
• Amazon Simple Notification Service
• Nagios

For the full list of notification modules, we can refer to https://docs.ansible.com/ansible/2.8/modules/list_of_notification_modules.html

Email:

---
- hosts: localhost 
  connection: local
  tasks: 
    - name: Read the machine uptime 
      command: uptime -p 
      register: uptime 
    - name: Send the uptime via e-mail 
      mail: 
        host: mail.fale.io 
        username: ansible@fale.io 
        password: PASSWORD 
        to: me@fale.io 
        subject: Ansible-report 
        body: 'Local system uptime is {{ uptime.stdout }}.' 

To sent the email, we will need the SMTP host, credential and content of the email. Do note that mail modules support the following

• The attachment parameter: To attach attachments
• The port parameter: port to use by the email server.
