Ansible Basic Playbook

Question: One of the Nautilus DevOps team members was working on to test an Ansible playbook on jump host. However, he was only able to create the inventory, and due to other priorities that came in he must work on other tasks. Please pick up this task from where he left off and complete it. Below are more details about the task:

The inventory file /home/thor/ansible/inventory seems to be having some issues; please fix them. The playbook needs to be run on App Server 3 in Stratos DC, so inventory file needs to be updated accordingly.

Create a playbook /home/thor/ansible/playbook.yml and add a task to create an empty file /tmp/file.txt on App Server 3.

Note: Validation will try to run playbook using command ansible-playbook -i inventory playbook.yml so please make sure 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. Create a inventory file and add the app server as per your task

thor@jump_host /$ vi /home/thor/ansible/inventory                       thor@jump_host /$ cat /home/thor/ansible/inventory stapp03 ansible_host=172.16.238.12 ansible_user=banner ansible_ssh_pass=BigGr33n    thor@jump_host /$

2. Create a Playbook file 

thor@jump_host /$vi /home/thor/ansible/playbook.yml thor@jump_host /$cat /home/thor/ansible/playbook.yml - name: Create file in appserver   hosts: stapp03   become: yes   tasks:     - name: Create the file       file:         path: /tmp/file.txt         state: touch thor@jump_host /$

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

thor@jump_host ~/ansible$ ansible all -a "ls -ltr /tmp/" -i inventory stapp03 | CHANGED | rc=0 >> total 4 drwx------ 2 banner banner 4096 Aug  3 15:20 ansible_command_payload_crUi5o thor@jump_host ~/ansible$ thor@jump_host ~/ansible$ ansible-playbook -i inventory playbook.yml   PLAY [Create file in appserver] *************************************************   TASK [Gathering Facts] ********************************************************** ok: [stapp03]   TASK [Create the file] ********************************************************** changed: [stapp03]   PLAY RECAP ********************************************************************** stapp03                    : ok=2    changed=1    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0     thor@jump_host ~/ansible$ thor@jump_host ~/ansible$ ansible all -a "ls -ltr /tmp/" -i inventory stapp03 | CHANGED | rc=0 >> total 4 -rw-r--r-- 1 root   root      0 Aug  3 15:21 file.txt drwx------ 2 banner banner 4096 Aug  3 15:21 ansible_command_payload_Dcfc5t thor@jump_host ~/ansible$
