获取正在运行的剧本的pid，以在该剧本中使用 [英] Get the pid of a running playbook for use within the playbook

问题描述

当我们在启用了详细输出的情况下运行剧本时，在ansible日志中，我们会看到类似以下内容:

When we run a playbook, with verbose output enabled, in the ansible logs we can see something like this:

2016-02-03 12:51:58,235 p=4105 u=root | PLAY RECAP

我猜想p=4105是剧本在运行时的pid.

I guess that the p=4105 is the pid of the playbook when it ran.

是否有办法在运行时(例如，作为变量)在剧本中获取此pid?

Is there a way to get this pid inside the playbook during its runtime (as a variable for example)?

推荐答案

这听起来有点像 XY问题，但是一种选择可能是使用shell命令生成一个shell，然后请求父PID:

This sounds a little like an XY problem, but one option may be to spawn a shell with the shell command and then ask for the parent PID:

- name: get pid of playbook
  shell: |
    echo "$PPID"
  register: playbook_pid

这将为您提供执行剧本的python进程的PID.

This will give you the PID of the python process that is executing the playbook.
