define variable list as a file in ansible playbook - linux

Question

Can someone help me in finding the best way to declare all variables inside a file and define the file path in ansible playbook? Here's my ansible-playbook
---
- hosts: myhost
vars:
- var: /root/dir.txt
tasks:
- name: print variables
debug:
msg: "username: {{ username }}, password: {{ password }}"
These are the contents inside dir.txt
username=test1
password=mypassword
When I run this, I am facing an error
TASK [print variables] *********************************************************************************************************
fatal: [121.0.0.7]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'username' is undefined\n\nThe error appears to be in '/root/test.yml': line 6, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n tasks:\n - name: print variables\n ^ here\n"}
Expected output is to print the variables by this method
Any help would be appreciated

Answer 1

There are two reasons why your code won't work.
A variables file should be in YAML or JSON format for Ansible to load it
Such variables files are loaded with vars_files directive or include_vars task, rather than vars
So a YAML file named /root/dir.yml:
username: test1
password: mypassword
Can be used in a playbook like:
---
- hosts: myhost
vars_files:
- /root/dir.yml
tasks:
- name: print variables
debug:
msg: "username: {{ username }}, password: {{ password }}"
