如何在Ansible中强制执行with_dict的顺序？

I have dictionary-type of data that I want to iterate through and keeping the order is important:

我有字典类型的数据，我想迭代并保持顺序很重要：

with_dict_test:
  one:   1
  two:   2
  three: 3
  four:  4
  five:  5
  six:   6

Now when I write a task to print the keys and values, they are printed in seemingly random order (6, 3, 1, 4, 5, 2).

现在当我编写一个打印键和值的任务时，它们以看似随机的顺序打印（6,3,1,4,5,2）。

---
- name: with_dict test
  debug: msg="{{item.key}} --> {{item.value}}"
  with_dict: with_dict_test

How can I enforce Ansible to iterate in the given order? Or is there anything better suited than with_dict? I really need both the key and the value during task execution...

如何强制Ansible按给定顺序迭代？或者有什么比with_dict更适合？在任务执行期间我真的需要密钥和值...

I don't see an easy way to use dicts as they determine there order from the order of its hashed keys.
You can do the following:

我没有看到使用dicts的简单方法，因为他们根据哈希键的顺序确定顺序。您可以执行以下操作：

with_dict_test:
  - { key: 'one', value: 1 }
  - { key: 'two', value: 2 }
  - { key: 'three', value: 3 }
  - { key: 'four', value: 4 }
  - { key: 'five', value: 5 }
  - { key: 'six', value: 6 }

and in the playbook just replace with_dict with with_items:

在playbook中只需用with_items替换with_dict：

---
- name: with_dict test
  debug: msg="{{item.key}} --> {{item.value}}"
  with_items: with_dict_test

If you find this solution (the declaration of the variable) to ugly, you can do this:

如果你发现这个解决方案（变量的声明）很难看，你可以这样做：

key: ['one', 'two', 'three', 'four', 'five', 'six']
values: [1, 2, 3, 4, 5, 6]

and in the playbook

并在剧本中

---
- name: with_dict test
  debug: msg="{{item.0}} --> {{item.1}}"
  with_together:
    - key
    - value

I'm not completely sure, but maybe this will help you along the way:

我不完全确定，但也许这会对你有所帮助：

  - hosts: localhost
    vars:
      dict:
        one: 1
        two: 2
        three: 3
      sorted: "{{ dict|dictsort(false,'value') }}"

    tasks:
      - debug:
          var: sorted
      - debug:
          msg: "good {{item.1}}"
        with_items: sorted

I'm assuming you can use the Jinja filter to somehow sort on complex values. Another thing you might check out is combining dict.values()|list and with_sequence, but anything you milk out of that stone won't exactly scream "maintainable."

我假设您可以使用Jinja过滤器以某种方式对复杂值进行排序。你可以检查的另一件事是结合dict.values（）| list和with_sequence，但你从那块石头中挤出的任何东西都不会完全尖叫“可维护”。
