How to pass variable while running playbook on command line
Let's take an example of below playbook which has variables
defined. You can see "vars" section of playbook. It has
multiple variables like pkg, myuser etc. Now user is looking
to change one variable during run time and rest can go same.
You need to just pass value if variable while running playbook
using option "-e".
# cat plabook-var.yml
# Playbooks for defining varibles
# vars should be defined before tasks
- name: Playbook for Learning Variables
hosts: all
vars:
pkg: vsftpd
myuser: testing
mypass: testing
webroot: /var/www/html
myurl: https://www.w3schools.com/jsref/prop_option_index.asp
tasks:
- name: Install package
yum:
name: "{{ pkg }}"
state: installed
- name: Create User
user:
name: "{{ myuser }}"
password: "{{ mypass | password_hash('sha512') }}"
- name: Create folder
file:
path: "{{ webroot }}/vijay"

- name: Download index file
get_url:

dest: /tmp
# ansible-playbook playbooks2/p1-varibale.yml -e pkg=httpdYou can also change multiple variable values as per your
requirement.
