Get the pid of a running playbook for use within the playbook

Question

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

Answer 1

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

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