Ansible：循环使用集合和角色

Question

我这周在 Ansible 中做了第一步，然后我中断了 include_tasks 以循环提供一个角色。 所需的任务是为一堆域创建 Letsencrypt 证书，感谢 T-Systems-MMS，已经有一个集合可以通过 letsencrypt 和 AutoDNS 的 API 来做到这一点（参见https://github.com/T-Systems- MMS/ansible-collection-acme/blob/master/docs/dns-challenge/autodns.md ）。

使用我的设置填充此剧本，它在一个域中运行良好。 我尝试循环是（希望在匿名化代码时没有错误）：

剧本_getsslcert_main.yml：

---
- hosts: localhost
  connection: local
  vars:
    ansible_python_interpreter: auto
  tasks:
    - name: Get SSL certificate
      include_tasks: playbook_getsslcert_task.yml
      loop:
        - sub1.domain1.com
        - sub2.domain1.com

剧本_getsslcert_task.yml：

---
- name: Doing letsencrypt ACME with AutoDNS
  collections:
    - t_systems_mms.acme
  roles:
    - acme
  vars:
    nbb_emailadress: my.email@example.com
    nbb_autodnsuser: login.user@other.com
    acme_domain:
      certificate_name: "{{ item }}"
      zone: "domain1.com"
      email_address: "{{ nbb_emailadress }}"
      subject_alt_name:
        - "{{ item }}"
    acme_challenge_provider: autodns
    acme_use_live_directory: true
    acme_conf_dir: /etc/letsencrypt
    acme_account_email: "{{ nbb_emailadress }}"
    acme_dns_user: "{{ nbb_autodnsuser }}"
    acme_dns_password: "supersecret"

我得到的错误是

fatal: [localhost]: FAILED! => {"reason": "conflicting action statements: hosts, roles\n\nThe error appears to be in 'playbook_getsslcert_task.yml': line 2, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n---\n- name: Doing letsencrypt ACME with AutoDNS\n  ^ here\n"}

我和我同事都是经验丰富的Linux大佬，我们测试了很多； 我们还用 formatcheckers 等检查了 YAML，做了不同的 styles 循环，尝试了一个例子 tasks.ym 只是为了写一条消息，检查文件格式（换行符，正确的 HEX 值，......）等等。 但是 Ansible 不喜欢这个剧本。

感谢您的所有建议。
