Reviewing and running the playbook

Putting everything together, we now have the following playbook (called common_tasks.yaml for simplicity):

--- 
- hosts: all 
  remote_user: ansible 
  tasks: 
    - name: Ensure EPEL is enabled 
      yum: 
        name: epel-release 
        state: present 
      become: True 
    - name: Ensure libselinux-python is present 
      yum: 
        name: libselinux-python 
        state: present 
      become: True 
  ...

Since this playbook is pretty complex, we can run the following:

$ ansible-playbook common_tasks.yaml --list-tasks  

This asks Ansible to print all the tasks in a shorter form so that we can quickly see what tasks a playbook performs. The output should be something like the following:

playbook: common_tasks.yaml
  play #1 (all): all TAGS: []
    tasks:
      Ensure EPEL is enabled TAGS: []
      Ensure libselinux-python is present TAGS: []
      Ensure libsemanage-python is present TAGS: []
      Ensure we have last version of every package TAGS: []
      Ensure NTP is installed TAGS: []
      Ensure the timezone is set to UTC TAGS: []
      Ensure the NTP service is running and enabled TAGS: []
      Ensure FirewallD is installed TAGS: []
      Ensure FirewallD is running TAGS: []
      Ensure SSH can pass the firewall TAGS: []
      Ensure the MOTD file is present and updated TAGS: []
      Ensure the hostname is the same of the inventory TAGS: []

We can now run the playbook with the following:

$ ansible-playbook -i test01.fale.io, common_tasks.yaml

We will receive the following output. Full code output is available on GitHub.
