Ansible Inventory Update

Question: The Nautilus DevOps team has started testing their Ansible playbooks on different servers within the stack. They have placed some playbooks under /home/thor/playbook/ directory on jump host which they want to test. Some of these playbooks have already been tested on different servers, but now they want to test them on app server 2 in Stratos DC. However, they first need to create an inventory file so that Ansible can connect to the respective app. Below are some requirements:

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

b. Add App Server 2 in this inventory along with required variables that are needed to make it work.

c. The inventory hostname of the host should be the server name as per the wiki, for example stapp01 for app server 1 in Stratos DC.

Note: Validation will try to run the playbook using command ansible-playbook -i inventory playbook.yml so please make sure the playbook works this way without passing 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 the task and verified the playbook and files existing

thor@jump_host ~$ ls -l /home/thor/playbook/ total 8 -rw-r--r-- 1 thor thor  36 Sep 28 07:04 ansible.cfg -rw-r--r-- 1 thor thor 250 Sep 28 07:04 playbook.yml thor@jump_host ~$ thor@jump_host ~$ cat  /home/thor/playbook/playbook.yml --- - hosts: all   become: yes   become_user: root   tasks:     - name: Install httpd package          yum:         name: httpd         state: installed         - name: Start service httpd       service:         name: httpd         state: started thor@jump_host ~$

2.  Create an inventory file and add the app server as per your task.

     (Refer to your task and add app server in inventory )

thor@jump_host ~$ vi /home/thor/playbook/inventory thor@jump_host ~$ cat /home/thor/playbook/inventory stapp02 ansible_host=172.16.238.11 ansible_ssh_pass=Am3ric@  ansible_user=steve thor@jump_host ~$

3.  Post file saved, run below command to execute the playbook 

thor@jump_host ~/playbook$ ansible-playbook  -i inventory playbook.yml   PLAY [all] *************************************************************************************************************************************************************   TASK [Gathering Facts] ************************************************************************************************************************************************* ok: [stapp02]   TASK [Install httpd package] ******************************************************************************************************************************************* changed: [stapp02]   TASK [Start service httpd] ********************************************************************************************************************************************* changed: [stapp02]   PLAY RECAP ************************************************************************************************************************************************************* stapp02                    : ok=3    changed=2    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0     thor@jump_host ~/playbook$
