Lab Information
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.
Lab Instructions
Step 1: Create the Inventory File
First, let's create the inventory file with all application servers:
bash
Create the directory if it doesn't exist
mkdir -p /home/thor/ansible
Create the inventory file
cat > /home/thor/ansible/inventory << EOF
[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
EOF
Step 2: Create the Playbook
Now, let's create the playbook that will copy the file:
cat > /home/thor/ansible/playbook.yml << 'EOF'
---
- name: Copy index.html to application servers
hosts: app_servers
become: yes
become_method: sudo
tasks:
- name: Ensure destination directory exists
file:
path: /opt/itadmin
state: directory
owner: root
group: root
mode: '0755'
- name: Copy index.html file to application servers
copy:
src: /usr/src/itadmin/index.html
dest: /opt/itadmin/index.html
owner: root
group: root
mode: '0644'
EOF
Step 3: Verify the Files
Check that both files were created correctly:
# Check inventory file
cat /home/thor/ansible/inventory
# Check playbook file
cat /home/thor/ansible/playbook.yml
Step 4: Test the Playbook
Run the playbook to test it:
cd /home/thor/ansible
ansible-playbook -i inventory playbook.yml
