来自 Ansible stdout_lines 结果的过滤器行

J. *_*ary 5 linux grep stdout filter ansible

我正在尝试从 Ansible stdout_lines 结果中过滤掉一行。我运行的 ansible playbook 任务是以下 shell 参数:

- name: VERIFY | Confirm that queue exists properly
  shell: aws sqs list-queues --region {{region}}
  environment: "{{ aws_cli_environment|d({}) }}"
  register: sqs_list

为了查看结果,我进行了调试:

- debug:
    msg: "{{ sqs_list.stdout_lines|list }}"

在剧本运行期间给出以下结果:

TASK [sqs : debug] ********************************************************************************************************************************************************************************************
ok: [localhost] => {
    "msg": [
        "{",
        "    \"QueueUrls\": [",
        "        \"sampleurl1\",",
        "        \"sampleurl2\",",
        "        \"sampleurl3\",",
        "        \"sampleurl4\",",
        "        \"https://sampleurl5/test_sqs\"",
        "    ]",
        "}"
    ]
}

我只希望最后一个 url,“test_sqs”出现在“msg”: 下,我尝试了以下过滤器,但没有运气:

- name: VERIFY | Find SQS url
  command: "{{ sqs_list.stdout_lines|list }} -- formats | grep $sqs"

aws cli 默认生成 JSON 输出,利用这个优势:

---
- hosts: localhost
  gather_facts: no
  tasks:
    - shell: aws sqs list-queues --region eu-west-1
      register: sqs_list
    - debug:
        msg: "{{ (sqs_list.stdout | from_json).QueueUrls | last }}"

输出:

TASK [debug] **************************************
ok: [localhost] => {
    "msg": "https://eu-west-1.queue.amazonaws.com/xxxxx/test"

您可以使用该--queue-name-prefix参数仅列出以 name 开头的队列test_sqs。如果只有一个具有该名称的队列,则可以使用此解决方案。
