Question

Ansible剧本只能在一个主机上运行

DECLARE @json NVARCHAR(MAX) = N'{
   "currency": {
    "0": {
      "ISOCode": "USD",
      "name": "US Dollar",
      "symbol": "$",
      "real": "$#,###.##",
      "free": "#,###.##"
    },
    "1": {
      "ISOCode": "IEP",
      "name": "Irish Pound or Punt",
      "symbol": "£",
      "real": "£#,###.##",
      "free": "#,###.##"
    },
    "2": {
      "ISOCode": "BEF",
      "name": "Belgian Franc",
      "symbol": "₣",
      "real": "#,###.##₣",
      "free": "#,###.##"
     }
   }
}'

SELECT j2.* 
INTO #TempCurrencyTable
FROm OPENJSON(@json, '$.currency') j1
CROSS APPLY OPENJSON(j1.[value]) WITH (
    currency INT
) j2

SELECT * 
FROM #TempCurrencyTable

实际输出是

任务[暂停渲染] ********************************************** ************************************************ [暂停渲染] 输出= {'失败'：错误，u'changed'：错误，u'stdout_lines'：[[u'hostname las-a'，u'logging-id hostname']]，u'stdout'：[u'主机名las-a \ nlogging origin-id主机名']}

我是“ las-a” ：好的：[las-a]

PLAY RECAP ********************************************* ****************************************************** ***** las-a：ok = 4更改= 0不可达= 0失败= 0跳过= 0获救= 0忽略= 0
las-b：ok = 3更改= 0不可达= 0失败= 0跳过= 0获救= 0忽略= 0

但是我想我是“ las-a”而我是“ las-b”

Answer 1

pause“ Pauses playbook execution ...”，即谁先到达它都会暂停所有分叉。

尝试调试，您将同时看到“ las-a”和“ las-b”。

- name: "Debug (was: pause with render)"
  debug:
    msg: "{{ lookup('template', 'conditional.j2') }}"

暂停的工作方式（可运行2.7.9）

使用库存进行测试

test_jails:
  hosts:
    test_01:
    test_02:
    test_03:

下面带有 run_once: yes

的剧本

- hosts: test_jails
  tasks:
    - pause:
        prompt: "Please enter the value"
        echo: yes
      register: result
      run_once: yes
    - debug:
        var: result.user_input

给予

PLAY [test_jails] ***************************************************************************

TASK [pause] ********************************************************************************
[pause]
Please enter the value:
[[ok: [test_01]

TASK [debug] ********************************************************************************
ok: [test_02] => {
    "result.user_input": "TEST"
}
ok: [test_01] => {
    "result.user_input": "TEST"
}
ok: [test_03] => {
    "result.user_input": "TEST"
}

PLAY RECAP **********************************************************************************
test_01                    : ok=2    changed=0    unreachable=0    failed=0   
test_02                    : ok=1    changed=0    unreachable=0    failed=0   
test_03                    : ok=1    changed=0    unreachable=0    failed=0

但是与 run_once: no 相同的剧本却给出了

PLAY [test_jails] ***************************************************************************

TASK [pause] ********************************************************************************
[pause]
Please enter the value:
[[ok: [test_01]

TASK [debug] ********************************************************************************
ok: [test_01] => {
    "result.user_input": "TEST"
}
ok: [test_02] => {
    "result.user_input": "VARIABLE IS NOT DEFINED!"
}
ok: [test_03] => {
    "result.user_input": "VARIABLE IS NOT DEFINED!"
}

PLAY RECAP **********************************************************************************
test_01                    : ok=2    changed=0    unreachable=0    failed=0   
test_02                    : ok=1    changed=0    unreachable=0    failed=0   
test_03                    : ok=1    changed=0    unreachable=0    failed=0

请注意test_01 PLAY RECAP中的ok=2。在这两种情况下，暂停仅执行一次。
没有run_once: yes的注册变量对其他主机不可用。

在ansible中对多个主机运行“查找”
