Hi,

I have a playbook with a task that greps for a string in a file. If the string is found the block should fail which is the case. However, in the fail module it fails to print the message.

Here is my playbook:

You're missing parenthesis around the condition.

Missing parentheses where?

My code is very similar to a working sample here:

fail:  
msg: \>-  
{{  
command\_result.stdout is search(‘775’) |  
ternary(  
"This REQ is already Deployed. ,  
“Database is not reachable.”  
)  
}}

Close the comparison into the parenthesis

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(command\_result.rc == 0) |

The filter "|" has higher precedence compared to the comparison "==". Without  
the parenthesis the filter is evaluated first and ternary returns "The  
Database is not reachable.". This string is compared to command\_result.rc and  
the result is "msg": "False"

HTH,
