Using ENVIRONMENT variables in kong configuration file in DB less mode

Questions
1

I am setting up Kon in DB less mode with kon_config.yml file. Using the documentation : DB-less and Declarative Configuration - v2.2.x | Kong Docs

$ export KONG_DATABASE=off
$ export TARGET_address=10.32.1.1:5000
$ kong start -c kong.conf

I want to be able to use variable TARGET_address inside kong.conf file.

Does the declarative configuration format support using environment variables? It does not appear to be documented here: DB-less and Declarative Configuration - v2.2.x | Kong Docs

Hello,

Declarative configuration does not currently support variable substitution. There is a workaround noted in this doc that may help you.

Create the config template file, then use the envsubst command to replace environment variable.
