task to assign result of a lookup to a registered variable

Hi,

Is there a way to assign the value of a lookup (in this case a password) to a variable and register it so that the registered variable can then be used in different tasks of play without having to call the lookup itself multiple times?

The closest I have got is using the debug module where I thought I could maybe register the msg. It is not working though as register is not a valid option for debug I think.

  • debug:
    msg: “{{ lookup(‘vault’,vaultLookupString) }}”

Ideally I would like a named task like below but this does not work.

  • name: Obtain password
    PASSWROD= “{{ lookup(‘vault’,vaultLookupString) }}”
    register: PASSWORD

  • name: Use registered PASSWORD from previous task to do stuff
    copy:
    dest:
    content:
    DB_USER=dbuser
    DB_PASSWORD= PASSWORD

  • name: Use registered PASSWORD again to do more stuff
    …

Currently I am having to do this which I want to avoid as more tasks rely on the password.

  • name: Use registered PASSWORD from previous task to do stuff
    copy:
    dest:
    content:
    DB_USER=dbuser
    DB_PASSWORD= “{{ lookup(‘vault’,vaultLookupString) }}”

Any help much appreciated.
