Lab Information
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 1 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 1 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.
Lab Solutions
STEP-BY-STEP SOLUTION
1️⃣ Create the inventory file
Run on the jump host:
vi /home/thor/playbook/inventory
Add the following inventory content:
[appserver1]
stapp01 ansible_host=172.16.238.10 ansible_user=tony ansible_ssh_pass=Ir0nM@n
Save & exit.
✔ Why this works:
stapp01 → required hostname according to wiki (server name)
ansible_host → correct IP for App Server 1
ansible_user → login user for that server
ansible_ssh_pass → its SSH password
2️⃣ Ensure your playbook.yml exists
The validation will run:
ansible-playbook -i inventory playbook.yml
So the directory /home/thor/playbook/ must contain playbook.yml.
cd /home/thor/playbook/
ls
3️⃣ Test the syntax
From inside /home/thor/playbook/ run:
ansible-playbook -i inventory playbook.yml --syntax-check
Should output:
playbook.yml: OK
4️⃣ Run the playbook (optional self-test)
Before validation, you can test:
ansible-playbook -i inventory playbook.yml
