ansible 沒有找到劇本中提到的角色

我對 Ansible 很陌生，所以我可能配置錯誤

$$ I have a Docker container running Ansible service in it I have an Ansible repository that include the Ansible files (this is a .Git repository $$

我的意願是自動將 vCenter 伺服器中的每個實驗室恢復為特定快照

所以，我（在ansible-roles-explained-with-examples 指南的幫助下）：

• ansible-galaxy init使用命令名稱創建了一個角色vcenter（參見下面的目錄樹）
• 在文件夾內創建了一些 vCenter 任務文件tasks（請參見下面的目錄樹）。以下是rever.yml任務文件的範例：

- name: Revert to a snapshot
 vmware_guest_snapshot:
   hostname: "{{ vcenter_hostname }}"
   username: "{{ vcenter_username }}"
   password: "{{ vcenter_password }}"
   datacenter: "{{ datacenter_name }}"
   state: revert
   snapshot_name: CLEAN
 delegate_to: localhost

• 在文件中提供 vCenter 憑據vcenter\vars\main.yml，如下所示：

# vars file for vcenter
vcenter_hostname: vcenter.foo.com
vcenter_username: hiddai@foo.com
vcenter_password: f#0$o#1$0o

• 將任務包含在tasks\main.yml帶有import-task密鑰的文件中，如下所示：

---
# tasks file for roles/vcenter
- import_tasks: poweroff.yml
- import_tasks: poweron.yml
- import_tasks: revert.yml
- import_tasks: shutdown.yml

• 創建了一個revert_lab.yml包含角色的劇本，就像這樣

---
- name: revert an onpremis lab
 hosts: all
 roles:
 - vcenter

在執行 playbook 以還原實驗室中的所有機器之前，我對 playbook 語法進行了一些檢查：

ansible-playbook playbooks/revert_lab.yml --syntax-check

我得到的錯誤是：

[WARNING]: Ansible is being run in a world writable directory (/ansible), ignoring it as an ansible.cfg source. For more information see
https://docs.ansible.com/ansible/devel/reference_appendices/config.html#cfg-in-world-writable-dir
[DEPRECATION WARNING]: Ansible will require Python 3.8 or newer on the controller starting with Ansible 2.12. Current version: 3.6.8 (default, Nov 16 2020, 16:55:22) [GCC
4.8.5 20150623 (Red Hat 4.8.5-44)]. This feature will be removed from ansible-core in version 2.12. Deprecation warnings can be disabled by setting 
deprecation_warnings=False in ansible.cfg.
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'
ERROR! the role 'vcenter' was not found in /ansible/playbooks/roles:/root/.ansible/roles:/usr/share/ansible/roles:/etc/ansible/roles:/ansible/playbooks

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

The offending line appears to be:

 roles:
 - vcenter
   ^ here

我決定ansible.cfg使用 a 鍵添加到我的儲存庫roles_path：

[defaults]
inventory = /ansible/inventories
roles_path = /ansible/roles
# roles_path = ./roles:..~/ansible/roles

我再次執行--syntax-check命令但得到了同樣的錯誤。我嘗試了不同類型的角色路徑語句 - 並得到了同樣的錯誤。當然ansible-playbook命令不起作用（帶有相同的錯誤消息）：

ansible-playbook playbooks/revert_lab.yml -i inventories/test/onpremis/domain.com/lab_r.yml

那麼，如何讓 ansible 辨識我的角色？

如何使 ansible 成功執行我的劇本？

ansible.cfg 與“故事”相關還是無關？

我的儲存庫：

Ansible 告訴你出了什麼問題：

[WARNING]: Ansible is being run in a world writable directory (/ansible), ignoring it as an ansible.cfg source. For more information see https://docs.ansible.com/ansible/devel/reference_appendices/config.html#cfg-in-world-writable-dir

這意味著您在 ansible.cfg 中的更改將被忽略。

修復此目錄的權限，然後重試。
