Example 1

hosts.yml

centos:
  hosts:
    provisioner:
      ansible_connection: local
    centos1:
      ansible_host: '192.168.77.22'
      ansible_port: 2345
ubuntu:
  hosts:
    ubuntu1:
      ansible_host: '192.168.77.23'

Tip

The setup module is at the core of Ansible. It gathers basic information about the remote hosts. By default it is always run at the beginning of each playbook. Check out the module's official documentation or run 

ansible-doc setup

Execute the following command and look for the Linux distribution name on the remote host 

ansible centos1 -m setup

What is the expected output of the command?

We expect the distribution to be set to CentOS.

Bonus round

Filter out the name of network interface on the remote host where the default IPv4 address is located. In order to complete the task

  • install jq on your system 
    sudo yum install -y jq
  • parse the setup module's output to make it a valid JSON (you can pipe the result of the Ansible command to sed '1c {')
  • use jq to find the corresponding key-pair value in the output (take a look at this tutorial to get a basic idea on how jq works). The key you are loooking for is under ansible_facts -> ansible_default_ipv4 -> interface.
