解析 ansible 事实时出现 ansible JMESPATH 错误

Question

我正在尝试从下面的 ansible 事实中过滤所有包含 "RegButton-" 的字符串，并将输出用作下一个播放中的项目列表。尝试使用 json_query 过滤器但失败并显示以下错误

可靠的事实

{
    "ansible_facts": {
        "srcgrpname": [
            "RegButton-48773",
            "test_vio",
            "RegButton-23395",
            "RegButton-520859",
            "RegButton-743141",
            "RegButton-297578",
            "RegButton-186156"
        ]
    },
    "changed": false
}

剧本条目

  - name: "Filter Regbutton policy Names"
    set_fact:
      srcgrpname2: "{{ resultid1 | json_query(query) }}"
    vars:
        query: "ansible_facts.srcgrpname[?contains(@, 'RegButton-') == `true`]"

我收到错误。

{
    "msg": "JMESPathError in json_query filter plugin:\nIn function contains(), invalid type for value: RegButton-48773, expected one of: ['array', 'string'], received: \"unknown\"",
    "_ansible_no_log": false
}

Answer 1

可以使用 select 和 regex。例如下面的任务

- set_fact:
    srcgrpname2: "{{ ansible_facts.srcgrpname|
                     select('regex', '^RegButton-(.*)$')|
                     list }}"
- debug:
    var: srcgrpname2

给予

"srcgrpname2": [
    "RegButton-48773", 
    "RegButton-23395", 
    "RegButton-520859", 
    "RegButton-743141", 
    "RegButton-297578", 
    "RegButton-186156"
]

笔记

这是 contains 的未决问题。
- json_query filter fails when using the functions "contains", "starts_with", others #27299
- Allow for subclassed types #158
可重现"RegButton-48773, expected one of: ['array', 'string'], received: unknown"
