ansible to store numeric value in register variable and check the condition statement

Question

I am using the below ansible playbook to check the root(/) size. if it's greater than 80%, then condition should be passed. But this is not working as expected. Can someone please help me with this.

 tasks:
- name: Check the space of the root
 shell: |
 df -h / | awk -F" " '{print 5ドル}' | sed 's/%//g' | tail -1
 register: disk_output
- debug:
 msg: "the root is greater than 80%"
 when: disk_output.stdout > 80

Answer 1

Ansible uses Jinja2 tests and filters in conditionals.

You can use the int filter to convert the disk_output.stdout to integer and proceed to compare it with the 80 value:

 - debug:
 msg: "the root is greater than 80%"
 when: disk_output.stdout | int > 80

cheers
