The Nautilus DevOps team is practicing some of the Ansible modules and creating and testing different Ansible playbooks to accomplish tasks. Recently they started testing an Ansible file module to create soft links on all app servers. Below you can find more details about it.
-
Write a playbook.yml under /home/thor/ansible directory on jump host, an inventory file is already present under /home/thor/ansible directory on jump host itself. Using this playbook accomplish below given tasks:
-
Create an empty file /opt/security/blog.txt on app server 1; its user owner and group owner should be tony. Create a symbolic link of source path /opt/security to destination /var/www/html.
-
Create an empty file /opt/security/story.txt on app server 2; its user owner and group owner should be steve. Create a symbolic link of source path /opt/security to destination /var/www/html.
-
Create an empty file /opt/security/media.txt on app server 3; its user owner and group owner should be banner. Create a symbolic link of source path /opt/security to destination /var/www/html.
Note: Validation will try to run the playbook using command ansible-playbook -i inventory playbook.yml so please make sure playbook works this way without passing any extra arguments.
Create the playbook.
cd /home/thor/ansible
vim playbook.yml ---
- hosts: stapp01
gather_facts: false
become: true
tasks:
- name: Create empty file
file:
path: /opt/security/blog.txt
state: touch
owner: tony
group: tony
- name: Create symbolic link
file:
state: link
src: /opt/security
dest: /var/www/html
- hosts: stapp02
gather_facts: false
become: true
tasks:
- name: Create empty file
file:
path: /opt/security/story.txt
state: touch
owner: steve
group: steve
- name: Create symbolic link
file:
state: link
src: /opt/security
dest: /var/www/html
- hosts: stapp03
gather_facts: false
become: true
tasks:
- name: Create empty file
file:
path: /opt/security/media.txt
state: touch
owner: banner
group: banner
- name: Create symbolic link
file:
state: link
src: /opt/security
dest: /var/www/html
Run the playbook.
ansible-playbook -i inventory playbook.ymlIf successful, it should return:
thor@jump_host ~/ansible$ ansible-playbook -i inventory playbook.yml
