在playbook中使用带有运算符的条件语句.当我运行playbook时,它从不接受/验证条件,而是考虑“shmall”的最后一个set_fact值.

- hosts: sandbox
user: robo
become: yes
gather_facts: yes
tasks:
- debug: msg="{{ansible_memtotal_mb}}"
- name: SHMALL value for MEM less than 16G
set_fact:
shmall: 3670016
when: ansible_memtotal_mb|int <= 16384
- name: SHMALL value for MEM is between 16G and 32G
set_fact:
shmall: 7340032
when: ansible_memtotal_mb|int > 16384 and ansible_memtotal_mb|int <= 32768
- debug: var=shmall

最佳答案
修复你的缩进. when不是set_fact动作的参数,而是任务的参数：
- name: SHMALL value for MEM less than 16G
set_fact:
shmall: 3670016
when: ansible_memtotal_mb|int <= 16384
- name: SHMALL value for MEM is between 16G and 32G
set_fact:
shmall: 7340032
when: ansible_memtotal_mb|int > 16384 and ansible_memtotal_mb|int <= 32768
