模板字符串时出现模板错误:意外的字符 u - Ansible

问题描述

当执行 playbook 在远程主机上运行命令并使用 shell 传递输出时，出现以下错误.

When executing a playbook to run a command in a remote host and pass the output using shell, getting below error.

致命:[master1]:失败！=> {} MSG:模板化时模板错误字符串:4 处的意外字符 u'a'.字符串:{{54aa7fda16833bff8358b6bd1157df2d9caa26b2}}

下面是我的剧本内容

- name: 'Play1'

  hosts: master

  tasks:

   - name: 'Execute command'

     shell: ''sh generate_ticket.sh" #command to generate ticket

     register: shell_output

   - name: 'debug shell_output'

     debug:

      var="{{ shell_output.stdout | from_yaml }}"

当我对 msg 尝试同样的操作并且不尝试过滤时，输出将被打印出来，没有任何错误.但是我更喜欢使用 var 因为它最适合我的进一步要求.如果票号是不同的字符串，我不会遇到任何问题.请参阅以下内容:

When I try the same with msg and don't try to filter then the output is printed without any error. However I prefer to use var as it suits best for my further requirements. If the ticket number is a different string I do not face any issues. Please see below:

输出:

ok: [master1] => {}


MSG:


54aa7fda16833bff8358b6bd1157df2d9caa26b2


Playbook :

- name: 'Play1'

  hosts: master

  tasks:

   - name: 'Execute command'

     shell: ''sh generate_ticket.sh" #command to generate ticket

     register: shell_output

   - name: 'debug shell_output'

     debug: msg="{{ shell_output.stdout | from_yaml }}"

推荐答案

当我在 shell_output.stdout

var="{{ 'shell_output.stdout' | from_yaml}}"

如果有人有比这更好的解决方法，请告诉我.

Let me know if anybody has a better fix than this.
