Ansible-忽略错误时间 [英] Ansible - ignore_errors WHEN

问题描述

Ansible 2.0.4.0

Ansible 2.0.4.0

大约有三个任务随机失败.失败的输出是:

There are about three tasks which randomly fails. The output of the fail is:

OSError: [Errno 32] 
Broken pipefatal: [machine1]: FAILED! => {"failed": true, "msg": "Unexpected failure during module execution.", "stdout": ""}

如果错误输出中出现Errno 32，是否可以忽略该错误.

Is it possible to ignore the error, if Errno 32 is in the output of the error.

- name: This task sometimes fails
  shell: fail_me!
  ignore_errors: "{{ when_errno32 }}"

我知道这是一种解决方法. 解决实际"问题可能会占用更多时间.

I"m aware this is a workaround. Solving the 'real' problem could take up way more time.

推荐答案

您可以使用 failed_when 控制任务何时在Ansible中失败，但是您不能使用

You can use failed_when to control when a task should fail in Ansible, but you cannot use ignore_errors for a specific return code, it is a simple yes/no switch.

因此，您可以添加一个表达式:

So in your case you can add an expression:

- name: This task sometimes fails
  shell: fail_me!
  register: fail_me
  failed_when: "fail_me.rc != 0 and fail_me.rc != 32"
