lastTimestamp 如果 eventTime . 因为这不适用于 sort -至少据我所知,我在考虑如何操纵阵列什么时候 上次时间戳 为空。

由于我是Ansible的新手,我不知道如何在适当的位置操纵列表来实现我的目标。或者有没有办法按两个属性排序?

set_fact 并在原始数据上循环以检查每一项(也就是说,我不认为通过简单地对原始数据应用一系列过滤器就可以得到解决方案)。

新列表中的新项目将通过将原始dict与包含正确日期的dict组合或使用空dict保留当前日期来获得。

---
- name: Process date and sort
  hosts: localhost
  gather_facts: false

  vars:
    # Your original data as json on a single line to shorten display
    api_events: [{"apiVersion": "v1", "count": 11, "eventTime": null, "firstTimestamp": "2020-10-20T16:17:08Z", "lastTimestamp": "2020-10-20T16:30:38Z", "involvedObject": {"apiVersion": "v1"}, "kind": "Event"}, {"apiVersion": "v1", "count": 11, "eventTime": "2020-10-20T16:17:10.182317Z", "firstTimestamp": null, "lastTimestamp": null, "involvedObject": {"apiVersion": "v1"}, "kind": "Event"}]

  tasks:
    - name: Process API events to determine time we will use
      vars:
        new_timestamp: "{{ item.firstTimestamp | ternary({}, {'firstTimestamp': item.eventTime}) }}"
        current_event: "{{ item | combine(new_timestamp) }}"
      set_fact:
        processed_api_events: "{{ processed_api_events | default([]) + [current_event] }}"
      loop: "{{ api_events }}"

    - name: Show result sorted
      debug:
        msg: "{{ processed_api_events | sort(attribute='firstTimestamp') }}"

它给出了:
