Problem statement

The Nautilus DevOps team needs to copy data from the jump host to all application servers in Stratos DC using Ansible. Execute the task with the following details:

a. Create an inventory file /home/thor/ansible/inventory on jump_host and add all application servers as managed nodes.

b. Create a playbook /home/thor/ansible/playbook.yml on the jump host to copy the /usr/src/itadmin/index.html file to all application servers, placing it at /opt/itadmin.

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

Solution

1. Create the Inventory File

  1. Navigate to the ansible directory:

    cd /home/thor/ansible/

  2. Create or edit the inventory file:

    vi inventory

  3. Add the following content to the inventory file:

    [app_servers]
stapp01 ansible_host=172.16.238.10 ansible_user=tony ansible_ssh_pass=Ir0nM@n
stapp02 ansible_host=172.16.238.11 ansible_user=steve ansible_ssh_pass=Am3ric@
stapp03 ansible_host=172.16.238.12 ansible_user=banner ansible_ssh_pass=BigGr33n

    This inventory file defines a group called app_servers with three application servers.

2. Create the Ansible Playbook

Create a playbook at /home/thor/ansible/playbook.yml to copy the file from the jump host to the application servers.

vi playbook.yml

Add the following content to the playbook file

---
- hosts: app_servers
  become: yes
  tasks:
    - name: Copy index.html on all application servers
      copy:
        src: /usr/src/itadmin/index.html
        dest: /opt/itadmin

This playbook will copy the index.html file from /usr/src/itadmin/ on the jump host to /opt/itadmin/ on each application server. The become: yes directive ensures that the file is copied with elevated privileges.

3. Run the Playbook

To execute the playbook and copy the file to all application servers:

  1. Run the playbook using ansible-playbook:

    ansible-playbook -i inventory playbook.yml

  2. Review the output:

    You should see output similar to this if everything is configured correctly:
