Incase a variable "outputmsg" has not been defined and assigned a value
using set_fact in the playbook I wish to assign a string value to the
variable.
Howver, if outputmsg is defined and is assigned some value which is the
case, i expect the below 'GET THE STATUS' message to be skipped.
Below is what I do:
- name: Set output message incase the process is already not RUNNING
tags: stop_tomcat
set_fact:
outputmsg: "{{ 'ALREADY in SHUTDOWN state' if
running_processes.stdout == '' else 'STOPPING NOW' }}"
- name: Status of Running process
tags: always
set_fact:
outputmsg: "{{ 'GET THE STATUS' if outputmsg is undefined }}"
I was expecting the above code to assign 'GETTING THE STATUS' incase
I'm getting the below error
TASK [Set output message incase the process is already not RUNNING]
> *****************************************************************************************
> task path: /app/startstop.yml:127
> ok: [10.9.9.111] => {"ansible_facts": {"outputmsg": "ALREADY in SHUTDOWN
> state"}, "changed": false}
>
> fatal: [10.9.9.111]: FAILED! => {"msg": "The task includes an option with

Can you please suggest ?
