Ansible Ping Module Usage Level 2 Ansible KodeKloud Engineer Task Success

  Question: The Nautilus DevOps team is testing Ansible playbooks on various servers within their stack. They've placed some playbooks under /home/thor/playbook/ directory on the jump host and now intend to test them on app server 2 in Stratos DC. However, an inventory file needs creation for Ansible to connect to the respective app. Here are the requirements:

a. Create an ini type Ansible inventory file /home/thor/playbook/inventory on jump host.

b. Include App Server 2 in this inventory along with necessary variables for proper functionality.

c. Ensure the inventory hostname corresponds to the server name as per the wiki, for example stapp01 for app server 1 in Stratos DC.

Note: Validation will execute the playbook using the command ansible-playbook -i inventory playbook.yml. Ensure the playbook functions properly without any extra arguments.

Please Note:-  Perform the below commands based on your question server,  user name & other details that might differ. So please read the task carefully before executing it. All the Best 👍

Solution:  

1. Go through the folder mentioned in task and verified the inventory edit user

thor@jumphost ~$  ls -l /home/thor/ansible/ total 4 -rw-r--r-- 1 thor thor 180 Jul 13 07:35 inventory thor@jumphost ~$  thor@jumphost ~$ cd /home/thor/ansible/ thor@jumphost ~$ vi inventory  thor@jumphost ~/ansible$ cat inventory  stapp01 ansible_host=172.16.238.10 ansible_ssh_pass=Ir0nM@n stapp02 ansible_host=172.16.238.11 ansible_ssh_pass=Am3ric@ stapp03 ansible_host=172.16.238.12 ansible_ssh_pass=BigGr33n ansible_user=banner thor@jumphost ~/ansible$

2.  Generate a SSH key on Jump Host . Please note it should Thor user 

  ( refer Video below for clarity )

thor@jumphost ~/ansible$   ssh-keygen -t rsa -b 2048 Generating public/private rsa key pair. Enter file in which to save the key (/home/thor/.ssh/id_rsa):  Enter passphrase (empty for no passphrase):  Enter same passphrase again:  Your identification has been saved in /home/thor/.ssh/id_rsa Your public key has been saved in /home/thor/.ssh/id_rsa.pub The key fingerprint is: SHA256:5yqKC4NthOEadY6C76uaU80IP/tmkjJ1UHqqMpFhS80 thor@jumphost.stratos.xfusioncorp.com The key's randomart image is: +---[RSA 2048]----+ |                 | |    .            | |. +o.            | |=*oE.            | |B*+B.   S .      | |=BB +    o       | |==+=      .      | |B*+.o .  .       | |**=Bo. ..        | +----[SHA256]-----+ thor@jumphost ~/ansible$

3.Copy SSH key to setup password-less authentication to the host mentioned in the task   

tthor@jumphost ~/ansible$ ssh-copy-id  banner@stapp03 /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/thor/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys banner@stapp03's password:  Number of key(s) added: 1 Now try logging into the machine, with:   "ssh 'banner@stapp03'" and check to make sure that only the key(s) you wanted were added. thor@jumphost ~/ansible$

4. validate the task by running the below command

thor@jumphost ~/ansible$ ansible stapp03 -m ping -i inventory  stapp03 | SUCCESS => {     "ansible_facts": {         "discovered_interpreter_python": "/usr/bin/python3"     },     "changed": false,     "ping": "pong" } thor@jumphost ~/ansible$

5. Click on Finish & Confirm to complete the task successful
