当条件处于 ansible 时

Question

I have written the following playbook and it's working fine but when I am doing the same thing with roles, when condition of the fail module is messing up. Irrespective of the values defined, when I am giving > in when, in fail module, it's skipping and when giving < , it's failing. Please don't mind the syntax and '-' s, it's messing up here.

- hosts: localhost
  vars: 
    vmcpu_list:
      - vmcpu: 2
      - vmcpu: 1
      - vmcpu: 1
    vcpu_value: 0 

  tasks:
    - set_fact: 
          vcpu_value: "{{ vcpu_value }} + vmcpu_list[{{item}}].vmcpu"
      with_sequence: start=0 end="{{ vmcpu_list | length -1 }}" 
    - debug:
           var: "{{ vcpu_value }}"
    - fail: 
          msg: " provided vcpu are more"
      when: vcpu_value|int > 5

NOTE: Sorry earlier I have given vcpu_value|int > 5 above but it should be vcpu_value|int > 3

 - fail: 
          msg: " provided vcpu are more"
      when: vcpu_value|int > 5

you have set vcpu_value: 0 condition assessement vcpu_value < 5 it dosn't match your condition ==> ansible will skip the task

   - fail: 
              msg: " provided vcpu are more"
          when: vcpu_value|int < 5

you have set vcpu_value: 0 condition assessement vcpu_value < 5 OK ==> ansible will get execute the task

There is no problem your code works fine no strange behavior ^^
