Question

我有一套可操作的游戏手册,要求——必须经过——并且想知道,是否有任何办法证实价值是清单变量之一。

抽样检测。

- hosts: localhost
  gather_facts: false
  vars:
    prod_mgmt_network: "{{ [ server00 ]|product(range(start,end))|map( join )|list }}"
    start: 4281
    end: 4283
  tasks:
    - debug:
        var: prod_mgmt_network

样本

ansible-playbook --extra-vars hostName=server004181 test.yml

Answer 1

您可使用assert或fail/code/<>/>/>/>a/>。


Using assert
- name: check that variable is defined using assert
  assert:
    that: hostname|default(  ) is in prod_mgmt_network
    fail_msg: "hostname is not in prod_mgmt_network"

其结果如下:
TASK [check that variable is defined using assert] ********************************************************************************************************
fatal: [localhost]: FAILED! => {
    "assertion": "hostname is defined",
    "changed": false,
    "evaluated_to": false,
    "msg": "hostname is not in prod_mgmt_network"
}

Using fail
- name: check that variable is defined using fail
  when: hostname|default(  ) is not in prod_mgmt_network
  fail:
    msg: "hostname is not in prod_mgmt_network"

其结果如下:
TASK [check that variable is defined using fail] **********************************************************************************************************
fatal: [localhost]: FAILED! => {"changed": false, "msg": "hostname is not in prod_mgmt_network"}

Using assert

Using fail
