Beats environment variable not working


I'm using Auditbeat 7.8.0, trying to pass value to configuration using environment variables under the processors - add_host_metadata.

I have exported the variable in my shell using the command export CITY_NAME="New York" and the Auditbeat config looks like below.

  - add_host_metadata:
      cache.ttl: 5m
        city_name: '$CITY_NAME'

But the output data generated is as below.

"geo" => {
                  "city_name" => "$CITY_NAME"

Could you please help me, to find if there is any changes to be made in order to get the proper output ?

Thanks in Advance

hi @mozam, have you tried using:

city_name: '${CITY_NAME}'
