Ansible：将数字附加到名称标签的任务

问题描述

我正在尝试在实例名称标签的末尾附加一个数字，我具有以下代码，但第二个任务有一个我找不到的问题，并且我无法找到一个示例任何其他试图解决此问题的人。

我对Ansible还是比较陌生，无法找到相关文档来做某些事情，例如如何在列表中查找值，例如我对直到：这可能是无效的语法

Ansible为2.9，可在实例本身上运行

我具有的任务被设置为执行以下操作

1. 获取属于同一启动模板的正在运行的EC2实例的列表
2. 与实例列表循环相同的次数，直到在ec2列表的名称标签中找不到基于项目索引的所需名称
3. 设置更新的标签名称

当前代码：

---
- name:                            "{{ role_name }} | Name Instance: Gather facts about current LT instances"
  ec2_instance_info:
    tags:
      "aws:autoscaling:groupName": "{{ tag_asg }}"
      "aws:ec2launchtemplate:id":  "{{ tag_lt }}"
      Application:                 "{{ tag_application }}"
    filters:
      instance-state-name:         [ "running" ]
  no_log:                          false
  failed_when:                     false
  register:                        ec2_list

- name:                            "{{ role_name }} | Name Instance: Generate Name"
  with_sequence:                   count="{{ ec2_list.instances|length }}"
  until:                           not "{{ tag_default_name }} {{ '%02d' % (item + 1) }}" in ec2_list.instances[*].tags['Name']
  when:                            tag_name == tag_default_name
  no_log:                          false
  failed_when:                     false
  register:                        item

- name:                            "{{ role_name }} | Name Instance: Append Name Tag"
  ec2_tag:
    region:                        eu-west-1
    resource:                      "{{ instance_id }}"
    state:                         present
    tags:
      Name:                        "{{ tag_default_name }} {{ '%02d' % (item + 1) }}"
  when:                            tag_name == tag_default_name
  no_log:                          false
  failed_when:                     false

根据要求，这是我得到的错误：

ERROR! no module/action detected in task.

The error appears to be in '/app/deploy/Ansible/roles/Boilerplate/tasks/name_instance.yml': line 14,column 3,but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


- name:                            "{{ role_name }} | Name Instance: Generate Name"
  ^ here
We could be wrong,but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:

    with_items:
      - {{ foo }}

Should be written as:

    with_items:
      - "{{ foo }}"

错误名称不正确：当任务正文中出现其他错误时，我会不断收到该错误

解决方法

第二个任务中似乎没有列出模块。您也许可以将debug用作模块，或者使用set_fact并跳过寄存器行。

我认为也可以将最后两个任务与一些更高级的循环结合起来，但是我不得不尝试一下，以提供一个可行的示例。

感谢bnabbs的回答，我意识到该版本的问题是缺少模块，在修复该问题之后，我完成了创建和测试该模块的工作，现在拥有一套可以正常工作的任务，从而产生了以下代码。
