Ansible 剧本条件

Question

我正在尝试将适用于 Windows 和 Linux 的剧本放在一起。现在我试图在剧本中包含只有在 Windows 或 Linux 下才会使用的角色，但它总是抱怨语法。我很感激这方面的任何帮助，因为我尝试了几种不同的方法，但总是失败。

- hosts: all
  gather_facts: no
  pre_tasks:
    - name: (localhost) make sure the known_hosts file is cleared
      lineinfile:
        path: ~/.ssh/known_hosts
        state: absent
        regexp: "^{{ ansible_host | replace('.', '\\.') }}.*$"
      delegate_to: 127.0.0.1

- hosts: all
  serial: 1
  pre_tasks:
    - name: (debug) print out some debug message to confirm inventory is properly set up
      debug:
        msg: "System inventory_hostname:{{ inventory_hostname }} ansible_host:{{ ansible_host }}"

- hosts: all
  tasks:
  - name: Install CA Trust Certs Windows
    include_tasks: tasks\install-certs-windows.yml
    when: ansible_os_family == 'Windows'

  - name: Install CA Trust Certs Linux
    include_tasks: tasks/install-certs-linux.yml
    when: ansible_os_family != 'Windows'

  roles:
  - { role: ansible-role-runnersbasics, tags: ["basics"] }
  - { role: ansible-role-docker, tags: ["docker"] }
  - { role: ansible-role-gitlab-runner }
    when: ansible_os_family == 'Windows'

错误：

ERROR! We were unable to read either as JSON nor YAML, these are the errors we got from each:
JSON: Expecting value: line 1 column 1 (char 0)

Syntax Error while loading YAML.
  did not find expected key

The error appears to be in 'playbook.yml': line 33, column 5, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  - { role: ansible-role-gitlab-runner }
    when: ansible_os_family == 'Windows'
    ^ here

从角色中删除花括号并在与角色处于同一级别时移动时

ERROR! We were unable to read either as JSON nor YAML, these are the errors we got from each:
JSON: Expecting value: line 1 column 1 (char 0)

Syntax Error while loading YAML.
  mapping values are not allowed in this context

The error appears to be in 'playbook.yml': line 30, column 43, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  roles:
    role: ansible-role-runnersbasics, tags: ["basics"] }
                                          ^ here

一句话：不要

好吧，如果你想对宫缩挑剔的话，那就是两个词。

无论如何....按操作系统对您的服务器进行分组，然后分别处理它们：

---
- hosts: Linux
  gather_facts: no
# Do Linux stuff

- hosts: Windoze
  serial: 1
# Do Windoze stuff
