将 with_items 应用于多个任务 [英] Apply with_items on multiple tasks

问题描述

是否可以将项目列表应用于 Ansible 剧本中的多个任务?举个例子:

Is it possible to apply a list of items to multiple tasks in an Ansible playbook? To give an example:

- name: download and execute
  hosts: server1
  tasks:
  - get_url: url="some-url/{{item}}" dest="/tmp/{{item}}"
    with_items:
    - "file1.sh"
    - "file2.sh"
  - shell: /tmp/{{item}} >> somelog.txt
    with_items:
    - "file1.sh"
    - "file2.sh"

是否有一些语法可以避免项目列表的重复?

Is there some syntax to avoid the repetition of the item-list?

推荐答案

截至今天，您可以将 with_items 与 include 一起使用，因此您需要拆分您的剧本分成两个文件:

As of today you can use with_items with include, so you'd need to split your playbook into two files:

- name: download and execute
  hosts: server1
  tasks:
  - include: subtasks.yml file={{item}}
    with_items:
    - "file1.sh"
    - "file2.sh"

和subtasks.yml:

- get_url: url="some-url/{{file}}" dest="/tmp/{{file}}"
- shell: /tmp/{{file}} >> somelog.txt

有一个请求使with_items适用于block，但 Ansible 团队表示永远不会支持它.

There was a request to make with_items applicable to block, but the Ansible team has said it will never be supported.
