基于结果的标准输出的 Ansible 条件? [英] Ansible conditional based on stdout of result?

问题描述

如何使用基于register:result的标准输出的when语句?如果存在标准输出，我希望运行 somecommand 如果不存在标准输出，我希望运行 someothercommand.

How do I use the when statement based on the standard output of register: result? If standard output exists I want somecommand to run if no standard output exists I want someothercommand to run.

- hosts: myhosts
  tasks:
  - name: echo hello
    command: echo hello
    register: result
  - command: somecommand {{ result.stdout }}
    when: result|success
  - command: someothercommand
    when: result|failed

推荐答案

尝试检查它是否等于空字符串?

Try checking to see it if equals a blank string or not?

- hosts: myhosts
  tasks:
  - name: echo hello
    command: echo hello
    register: result
  - command: somecommand {{ result.stdout }}
    when: result.stdout != ""
  - command: someothercommand
    when: result.stdout == ""
