hosts 檔案

192.168.10.11 key=13

192.168.10.12

[web:vars]

key=test

var.yaml 檔案

---

- hosts: all

gather_facts: Flase

tasks:

- name : display host variables

debug: msg="The {{ inventory_hostname }} vaule is {{ key }}"

擷取變量值

#ansible-playbook -i hosts var.yaml

PLAY [all] ********************************************************************

TASK: [display host variables] ************************************************

ok: [192.168.10.11] => {

"msg": "The 192.168.10.11 vaule is 13"

}

ok: [192.168.10.12] => {

"msg": "The 192.168.10.12 vaule is test"

PLAY RECAP ********************************************************************

192.168.10.11 : ok=1 changed=0 unreachable=0 failed=0

192.168.10.12 : ok=1 changed=0 unreachable=0 failed=0

PS:當hosts定義了key值，以hosts定義變量優先，如hosts未定義變量，則取hosts中web:vars中變量值
