ModuleNotFoundError: No module named 'server_types' Ansible 模塊開發

Question

我正在學習如何開發自己的 ansible 模塊。 我有這個劇本來測試我的新模塊test_playbook.yml ：

---
-
  hosts: all

  tasks:
    - name: Suspend MNR
      realtime_server:
        server_type: 'MNR'
        action: 'suspend'
      ignore_errors: True

    - name: All done
      local_action: debug msg="All done"
      run_once: True

我在./library目錄中有我的 python 代碼：

ansible@ubuntu-c:~/realtime_server/TEST_LAB_FILES/library$ ls -la
total 16
drwxr-xr-x  8 ansible ansible  256 Aug  1 01:09 .
drwxr-xr-x 16 ansible ansible  512 Aug  1 01:10 ..
-rw-r--r--  1 ansible ansible  352 Aug  1 00:44 object_factory.py
-rw-r--r--  1 ansible ansible 1067 Aug  1 01:05 realtime_server.py
-rw-r--r--  1 ansible ansible 3745 Aug  1 01:06 server_types.py

這是我的realtime_server.py文件的內容：

#!/usr/bin/python3
from ansible.module_utils.basic import AnsibleModule
import server_types

ANSIBLE_METADATA = {
    'metadata_version': '1.1',
    'status': ['preview'],
    'supported_by': 'community'
}

DOCUMENTATION = r''' '''

EXAMPLES = r''' '''


def run_server_action(server_type, action):
    rt_server = server_types.factory.create(name=server_type, action=action)
    rt_server.execute(action=action)


def run_module():
    # define the available arguments/parameters that a user can pass to the module
    module_args = dict( server_type=dict(type='str', required=True), action=dict(type='str', required=True) )
    result = dict( changed=False )
    module = AnsibleModule( argument_spec=module_args, supports_check_mode=True )

    if module.check_mode:
        return result

    if module.params.get('server_type'):
        if module.params.get('action'):
            run_server_action(module.params.get('server_type'),
                              module.params.get('action'))


def main():
    run_module()

if __name__ == '__main__':
    main()

我是否必須將所有 python 代碼放入realtime_server.py文件中？

當我運行我的劇本時，我得到了這個 output：

ansible@ubuntu-c:~/realtime_server/TEST_LAB_FILES$ ansible-playbook -i hosts -l centos1 test_playbook.yml

感謝如何將 a.py 文件導入 Ansible 模塊？ 我能夠弄清楚該怎么做。

我將我的支持 python 代碼放在./module_utils目錄中。 然后在我的 ansible 模塊文件 realtime_server.py 我有：

try:
    from ansible.module_utils.server_types import factory
except:
    from server_types import factory
