ModuleNotFoundError：没有名为'server_types' Ansible 模块开发

Question

我正在学习如何开发自己的ansible模块。我有这个剧本来测试我的新模块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目录中有我的python代码：

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

以下是我的realtime_server.py文件的内容：

#!/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()

我必须把我所有的python代码都放在realtime_server.py文件中吗？

当我运行我的剧本时，我会得到这样的输出：

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

感谢如何将.py文件导入Ansible模块？我想好了该怎么办。

我把我支持的python代码放在./module_utils目录中。然后在我的ansible模块文件realtime_server.py中，我有：

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