Question

我正在创建一个提示用户输入他/她想要的包裹的Ansible剧本，但我希望它能够不断提示用户输入包裹，直到他/她输入“完成”为止。以及如何安装用户在任务中输入的每个软件包？下面是我使用vars_prompt的代码，但是我需要帮助将其更改为我想要的功能。

---
- hosts: localhost
  vars_prompt:
    - name: packages
      prompt: "Enter the packages you want to install. Enter 'done' to stop."
      private: no
  tasks:
    - name: install packages user desired
      yum:
        name: "{{ packages }}"
        state: installed

Ansible确实不是为这种交互式操作而设计的。

一种选择是允许操作员指定以逗号分隔的软件包列表，如下所示：

---
- hosts: localhost
  vars_prompt:
    - name: packages
      prompt: "Enter the packages you want to install, separated by commas"
      private: no
  tasks:
    - name: install packages user desired
      yum:
        name: "{{ packages.split(',') }}"
        state: installed

如果您确实需要单独的提示，则可以用shell脚本包装剧本，然后将结果写入到您提供的文件中，作为对剧本的输入：

#!/bin/bash

item=1
packages=()
echo "Enter packages to install. Enter 'done' to stop."
while :; do
    read -p "$(( item++ )). " package
    [[ $package = done ]] && break
    packages+=($package)
done

(
    first=1
    echo '{"packages": ['
    for package in "${packages[@]}"; do
        [[ $first != 1 ]] && echo ","
        first=0
        echo "\"$package\""
    done
    echo ']}'
) > packages.json

ansible-playbook playbook.yml -b -e @packages.json

在这种情况下，您的剧本看起来像：

---
- hosts: localhost
  gather_facts: false
  tasks:
    - name: install packages user desired
      yum:
        name: "{{ packages }}"
        state: installed
