Ansible：替换无法找到本地现有的文件

test.conf我正在尝试使用 Ansible替换配置文件中的单个字符串。

这是我的职责的两项任务：

- name: Check for conf locally
  local_action: stat path="{{ role_path }}/files/test.conf"
  register: stat_config

# Place test_var within the test conf file
- replace:
    dest: "{{ role_path }}/files/test.conf"
    regexp: 'to_be_replaced'
    replace: "{{test_var}}"
  when: stat_config.stat.exists == True

在第一个中，我检查文件是否存在（本地），在第二个中，我尝试to_be_replaced用 var替换"{{test_var}}"。以下是输出：

 TASK [app : Check for conf locally] *********************************************************
task path: /home/ubuntu/src/share/playbooks/roles/app/tasks/main.yml:27

TASK [app: replace] *******************************************************************************
task path: /home/ubuntu/src/share/playbooks/roles/app/tasks/main.yml:32
fatal: [app001]: FAILED! => {"changed": false, "msg": "Path /home/ubuntu/src/share/playbooks/roles/app/files/test.conf does not exist !", "rc": 257}

正如您所看到的，第一个任务在test.conf这里找到了该文件/home/ubuntu/src/share/playbooks/roles/app/files/test.conf，但是第二个任务在同一路径上找不到它..！

我做错了什么？

我们无法从输出中确定，但您的第二个任务并非专门在本地主机上。请尝试：

# Place test_var within the test conf file
- replace:
    dest: "{{ role_path }}/files/test.conf"
    regexp: 'to_be_replaced'
    replace: "{{test_var}}"
  when: stat_config.stat.exists == True
  delegate_to: localhost
