如何使用 vars_prompt 和命令行接受用戶輸入？

我開始使用 Ansible 已經幾個月了。 在本教程中，如果您可能希望在運行 ansible playbook 時prompt the user輸入某些輸入，我們將介紹如何使用vars_prompt ansible section 。

讓我們開始吧：

第1步

創建hosts文件並將其放在名為/Users/Shared/ansible的文件夾下。

hosts

[ local ]
localhost ansible_connection = local ansible_python_interpreter = python
 
[ defaults ]
host_key_checking = false
 
[ crunchify ]
localhost

第2步

將您的默認ansible.cfg文件放在同一文件夾下。

1
2
3
4
[ defaults ]
ansible_ssh_user = crunchify
inventory = hosts
host_key_checking = false

第三步

創建文件crunchify.yml文件，我們將在其中使用vars_prompt部分來獲取用戶輸入。

- hosts : crunchify
   connection : local
   vars_prompt :
 
    - name : website
       prompt : "What is your website?"
       private : no
 
    - name : country
       prompt : "Enter Country Name?"
       private : no
 
   tasks :
 
    - debug :
         msg : 'Website name: {{ website }}. Country name: {{ country }}'

第四步

運行 ansible 劇本。

如何跳過用戶提示並通過命令行接受參數：

1
bash - 3.2 $ ansible - playbook - vvv crunchify . yml - e "website='Crunchify.com' country='United States'"
