Lab: Ping Hosts

Overview

In this lab, you will learn how to confirm the connection between your ansible machine and hosts.

We will use the ping module for this purpose.

Duration

Estimated Time: 20 minutes

Step 1: Understanding the ping Module

The ping module is used to verify connectivity between Ansible and its hosts.

The default syntax for using the ping module is:

ansible <Pattern> -m ping

---

Step 2: Running a Sample Command

Run the following command to test the connection:

ansible webservers -m ping

Expected Output:

<IP 1> | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python3"
    },
    "changed": false,
    "ping": "pong"
}

Key Points:

• SUCCESS: Indicates that Ansible successfully connected to the hosts.
• changed: false: Confirms that no changes were made on the hosts.
• ping: "pong": Confirms connectivity between Ansible and the hosts.

Note: This is not an ICMP ping; it is a test of Ansible's ability to connect to the hosts.

Extra:

to skip ssh key checking, you can add the following line to the ansible configuration file:

sudo nano /etc/ansible/ansible.cfg

add this line:

[defaults]
host_key_checking = False

Well Done! 👏

You have successfully verified connectivity using the ping module!
